The supercritical carbon dioxide (SC-CO 2 ) dyeing technology is a green dyeing technology, and the usage of natural dye makes SC-CO 2 dyeing technology safer and more environment-friendly. Nevertheless, after using natural dye in SC-CO 2 dyeing, the color depth and fastness of dyed natural fabric are poor. In this study, alkyl and hydroxyalkyl groups were grafted onto alizarin, which is a natural dye, to elevate the color depths and fastness of alizarin-derivative-dyed natural fabric. The results demonstrate that the color depths of alkyl-alizarin-dyed and hydroxyalkyl-alizarin-dyed natural fabrics were increased. This has to do with the increase in the solubilities of alkyl alizarin and hydroxyalkyl alizarin in SC-CO 2 . The hydroxybutyl-alizarin-dyed wool displayed the best color depth (K/S value: 6.44). And the hydroxyalkyl-alizarin-dyed natural fabric showed good washing fastness and rubbing fastness (about 4–5 level), because that hydroxyalkyl alizarin could be linked by a covalent bond to the natural fabric.

Dried shrimp is a popular dietary ingredient that is often included in appetizer soups, stir-fry dishes, or other stews to improve the umami taste. The effects of adding dried shrimp on the sensory characteristics and taste components of sheep bone soup were investigated through sensory evaluation and untargeted approaches. The results of the single-factor and orthogonal experiments showed that the flavor qualities of sheep bone soup were optimal under the following conditions: 30% dried shrimp added, a 1:4.5 material–water ratio, and 2.7 h of stewing time. Sensory analysis showed a significant increase in the aroma, umami, kokumi, and texture intensity of the optimized sheep bone soup with dried shrimp. The untargeted approach combined with multivariate statistical analysis showed that compounds with a sweet taste (Lys and Ser), a umami taste and umami enhancement (Ala-Leu, Glu-Pro, Glu-Glu, Asp-Phe, pyroglutamic acid, and cinnamic acid), a bitter taste (Gly-Leu, Leu-Leu, Ile-Lys, and taurine), a kokumi taste (γ-Glu-Met, γ-Glu-Leu, γ-Glu-Ile, N-acetylmethionine, and N-acetylphenylalanine), a sour taste (malic acid), and a popcorn-like aroma (2-acetylthiazole) contributed significantly to the flavor enhancement of sheep bone soup. In addition, the contribution of Ac-Ser-Asp-Lys-Pro could not be ignored. These results contribute to a better understanding and improvement of the flavor qualities of sheep bone soup.

An essential function carried out by bile acids (BA) is to aid in lipid absorption, as they emulsify lipids and combine with them to form chylomicrons. While BA have been utilized as lipid emulsifiers in monogastric and aquatic animals, their impact on ruminants remains relatively unexplored. Two experiments were conducted to investigate the effects of BA on the lipid absorption of lactating dairy goats. In experiment 1, twelve lactating goats with similar days in milk (42 ± 2 d), body weight (46.2 ± 5.1 kg), and milk yield (1.62 ± 0.33 kg) were administered four BA doses (0, 1, 2, or 4 g/d) to explore the effects of BA supplementation. The results observed a positive correlation between the BA dose and plasma total bile acid concentration ( P < 0.001). Notably, when goats received BA, there was a trend of increase in the proportion of preformed fatty acids in milk ( P = 0.079). In experiment 2, eighteen lactating goats with similar days in milk (100 ± 6 d), body weight (45.0 ± 3.7 kg), and milk yield (1.60 ± 0.31 kg) were divided into two groups (HF and HFB): HF group received no BA, while HFB group received BA (4 g/d). Both the groups were fed diets with fat powder supplementation (1% of dry material) for 5 weeks. BA supplementation led to a significant increase in milk yield ( P = 0.024) and fat concentration ( P = 0.045). Meanwhile, there was a significant rise of total bile acid concentration in plasma ( P < 0.001), rumen ( P < 0.001) and feces ( P < 0.001). Additionally, BA supplementation had a significant impact on blood metabolism, up-regulating 241 metabolites and down-regulating 208 metabolites ( P < 0.05). BA supplementation also altered the correlations among various plasma lipid components ( P < 0.05). In fatty acid (FA) analysis, 26 different FA were detected, out of which 16 showed significant down-regulation upon BA supplementation ( P < 0.05). In conclusion, BA supplementation positively influenced lactating dairy goats, particularly when fed diets with fat powder supplementation. BA supplementation enhanced milk yield, improved milk fat concentration, and significantly altered lipid-related blood metabolism. These findings suggest that BA supplementation could be a valuable strategy for enhancing dairy production and lipid metabolism in dairy goats, offering potential benefits for the dairy industry.

The application of protease as a biocatalyst for the anti-felting finishing of wool has been widely explored. However, commercial proteases tend to hydrolyze the non-keratinized proteins in the cell membrane complex (CMC) layer while removing wool scales, resulting in excessive hydrolysis and unacceptable fiber damage. Herein, chitosan oligosaccharide (COS) was covalently grafted to papain using carbodiimide/N-hydroxysuccinimide (EDC/NHS) to prepare a less-destructive modified protease of Pap-COS. Subsequently, one-bath anti-felting finishing of wool was carried out using reducing agent and Pap-COS, aiming at achieving low shrinkage and reduced strength loss. The results reveal that Pap-COS achieved a larger particle size than native papain, accompanied by a prolongation of its half-life and a decrease in the thermal inactivation rate, demonstrating improved stability. Under the same incubation conditions, the felting shrinkage of wool fabrics treated with papain and Pap-COS was similar (approximately 5 %). In contrast, native papain caused a 20.82 % decrease in fabric strength, while Pap-COS resulted in a substantially lower decrease (8.10 %), meeting the requirements of commercial woolen products. Furthermore, the dyeing performance and wearability of the Pap-COS-treated wool fabrics were also dramatically improved. The present work provides an alternative for eco-friendly shrink-resistant finishing of woolen textiles in wool industry.

Developing low-cost and stable adsorbent is urgent and attractive to remove hazardous dye from water. In this study, zirconium based metal-organic framework (NH 2 -UiO-66) was grown on waste wool fibers and the fabricated composite adsorbent (NH 2 -UiO-66/wool) was used to remove anionic dye methyl orange (MO). After characterizing the adsorbents, we determined the effect of pH and initial concentration of MO on adsorption performance. Moreover, adsorption kinetics and isotherms were conducted to reveal the adsorption mechanism. The results showed that NH 2 -UiO-66/wool achieved the highest adsorption capacity at natural pH with the maximum adsorption of 61.0 mg/g adsorbent, which is higher than most biomass based adsorbents. Moreover, NH 2 -UiO-66/wool enabled a broad range of pH (3−11) and initial concentration of MO (10–50 mg/L). Adsorption kinetics and isotherms of NH 2 -UiO-66/wool fitted well with pseudo-second-order model and Langmuir mode, respectively. NH 2 -UiO-66/wool presented 40.3 times higher of kinetics constant than that of original wool in the presence of initial MO concentration of 10 mg/L due to the positive nature of NH 2 -UiO-66. Ultimately, NH 2 -UiO-66/wool presented excellent regeneration ability with 500 mg/L NaCl solution and regeneration efficiency remained 98% after 10 cycles. Overall, this work may provide new insights into the development of MOFs/wool adsorbents for enhanced dye removal.

A novel and durable organic-inorganic flame retardant (FR) system for wool fabric was fabricated using natural phytic acid (PA), titanium dioxide (TiO 2 ) nanoparticles and 1,2,3,4-butanetetracarboxylic acid (BTCA). In order to address the diffusion barrier action of wool fiber to the FR agents, an additional exhaustion process was employed ahead of the traditional pad-dry-cure procedure. The flame retardancy, smoke generation, thermal stability, and washing durability of the treated fabrics were discussed. The PA/TiO 2 /BTCA system endowed wool fabric with excellent flame retardancy and washing durability. The treated fabric was still able to self-extinguish after 30 washing cycles. Moreover, the FR system effectively reduced the smoke generation capacity. Thermogravimetry test shows that the FR system altered the thermal decomposition behavior of wool, and the formation of thermal protective intumescent char mainly contributed to the improved flame retardancy, revealing a significant condensed-phase FR mechanism of the treated wool.

Background Probiotics are being considered as valuable microorganisms related to human health. Hu sheep is referred as one of the important sheep breeds in China. Goat milk produced by Hu sheep is characterized with high nutritional value and hypoallergenic in nature. Particularly, this milk contains plenty of milk prebiotic and probiotic bacteria. This study was aimed to scrutinize more bacterial strains from Hu sheep milk with potential probiotic activity.Results Based on 16S rRNA sequence analysis, pool of forty bacterial strains were identified and evaluated their antimicrobial activities against Staphylococcus aureus, enterohemorrhagic Escherichia coli (EHEC), Salmonella typhimurium, Listeria monocytogenes enterotoxigenic E. coli (ETEC) and Aeromonas caviae. Four out of these isolated strains demonstrated their efficient bacteriostatic ability and potential healthy properties. We also examined the safety aspects of these bacterial candidates including three Lactococcus lactis strains (named as HSM-1, HSM-10, and HSM-18) and one Leuconostoc lactis strain (HSM-14), and were further evaluated via in vitro tests, including antimicrobial activity, cell surface characteristics (hydrophobicity, co-aggregation, and self-aggregation), heat treatment, antibiotic susceptibility, simulated transport tolerance in the gastrointestinal tract, and acid/bile tolerance. The obtained results revealed that HSM-1, HSM-10, HSM-14, and HSM-18 showed high survival rate at different conditions for example low pH, presence of bovine bile and demonstrated high hydrophobicity. Moreover, HSM-14 had an advantage over other strains in terms of gastrointestinal tract tolerance, antimicrobial activities against pathogens, and these results were significantly better than other bacterial candidates.Conclusion Hu sheep milk as a source of exploration of potential lactic acid bacteria (LAB) probiotics open the new horizon of probiotics usage from unconventional milk sources. The selected LAB strains are excellent probiotic candidates which can be used for animal husbandry in the future. Rationale of the study was to utilize Hu sheep milk as a source of potential probiotic LABs. The study has contributed to the establishment of a complete bacterial resource pool by exploring the Hu sheep milk microflora.

Marine bacteria play a key role in marine ecosystems and are one of the main causes of biofouling. Biofouling of adsorbents that are used for uranium recovery usually results in a decrease in uranium recovery. A novel adsorbent with antibacterial activity for uranium recovery in bacterial environments was prepared in our study to address this concern. Amidoxime-functionalized wool fibers with nano-TiO2 particles (Wool-AO@TiO2) was synthesized by radiation-induced graft polymerization combined with in situ coprecipitation of nano-TiO2 particles onto the wool fibers. The presence of nano-TiO2 on the adsorbent was verified by scanning electron microscopy with energy-dispersive X-ray spectroscopy. The maximum uranium adsorption capacity of Wool-AO@TiO2, acquired from the Langmuir isotherm, was 113.12 mg/g. The introduced nano-TiO2 imparted excellent antibacterial activity to Wool-AO@TiO2. The inhibition of Staphylococcus aureus and Escherichia coli by Wool-AO@TiO2 was 95.2% and 90%, respectively. The adsorption capacity was mostly unaffected in bacterial environments, even after four cycles of culturing with bacteria. These results suggest that the prepared Wool-AO@TiO2 adsorbent may promote the development of novel antifouling adsorbents for uranium recovery from seawater.

Tall fescue ( Festuca arundinacea Schreb.) is a widely used cool-season turfgrass, and its growth is mainly limited by water deficit. Abscisic acid (ABA) and brassinolide (BR) are two important stress hormones regulating plant physiological processes and growth under water deficit. To investigate effects of exogenous ABA and BR on physiological and photosynthetic performance of tall fescue under water stress conditions, ABA (10 and 20 mg L −1 ) and BR (0.4 and 0.8 mg L −1 ) were applied individually and in combination (0.4 mg L −1 BR and 10 mg L −1 ABA) under three soil water regimes [75 ± 5% FC (HW), 50 ± 5% FC (MW) and 25 ± 5% FC (LW)] in the greenhouse. Results revealed that ABA and BR application markedly decreased the relative conductivity and malondialdehyde, notably increased leaf relative water content, antioxidant enzyme activity and proline content under water stress. ABA plus BR application was equally effective in improving the activities of antioxidant enzyme as ABA at 20 mg L −1 . ABA application reduced stomatal conductance and decreased both transpiration and net photosynthetic rate ( P n ), while BR application significantly increased P n and water use efficiency (WUE) by enhancing chlorophyll content. The ABA and BR combination application showed higher P n and WUE as well as BR single application. It indicated that ABA and BR combination application increased photosynthetic capacity, and reduced the effect on photosynthetic loss caused by ABA under water stress. All these confirmed that ABA plus BR application exhibited a synergistic interaction on enhancing drought tolerance and photosynthesis of tall fescue under water stress.

Morchella esculentais an edible mushroom with special flavor and high nutritional value for humans, primarily owing to its polysaccharide constituents.M. esculentapolysaccharides (MEPs) possess remarkable pharmaceutical properties, including antioxidant, anti-inflammatory, immunomodulatory, and anti-atherogenic activities. The aim of this study was to evaluate the in vitro and in vivo antioxidant potential of MEPs. In vitro activity was determined using free radical scavenging assays, whereas in vivo activity was evaluated through dextran sodium sulfate (DSS)-induced liver injury in mice with acute colitis. MEPs effectively scavenged 1,1-diphenyl-2-picrylhydrazyl and 2,2-azinobis-6-(3-ethylbenzothiazoline sulfonic acid) free radicals in a dose-dependent manner. Additionally, DSS-induced mice showed severe liver damage, cellular infiltration, tissue necrosis, and decreased antioxidant capacity. In contrast, intragastric administration of MEPs showed hepatoprotective effects against DSS-induced liver injury. MEPs remarkably elevated the expression levels of superoxide dismutase, glutathione peroxidase, and catalase. Additionally, it decreased malondialdehyde and myeloperoxidase levels in the liver. These results indicate that the protective effects of MEP against DSS-induced hepatic injury could rely on its ability to reduce oxidative stress, suppress inflammatory responses, and improve antioxidant enzyme activity in the liver. Therefore, MEPs could be explored as potential natural antioxidant agents in medicine or as functional foods to prevent liver injury.Keywords:Morchella esculenta;polysaccharide;antioxidant;ulcerative colitis;oxidative stress

An electronic nose based on metal oxide sensors was used to measure goaty flavor in goat milk samples. To study the relationships between electronic nose data, sensory data, and levels of free fatty acids (FFA), multivariate partial least square regression (PLS) was carried out. The electronic nose system evaluation correlated well with sensory evaluation. The coefficients of determination (R 2 ) of the PLS models reached 90.0%. The electronic nose, combined with principal component analysis and linear discriminant analysis, can discern among goat milk samples with different goaty flavor intensities. In addition, Fisher discriminant analysis and back-propagation neural network were carried out to evaluate goaty flavor intensity, and the prediction accuracies were 98.2 and 100.0%, respectively. The electronic nose is a potentially useful tool to evaluate goaty flavor intensity in goat milk samples.

Objective Improving total hair follicle density (THFD) can directly result in increased fiber yield in cashmere goats. However, its phenotypic and genetic characteristics remain poorly understood. This study aimed to investigate the spatial distribution and associated genes of THFD in goats. Methods A large-scale histological image analysis was conducted on 791 skin samples to characterize the spatial distribution of THFD at the local-site (n = 7), body-side (32 sites, n = 224), and whole-body (14 sites, n = 560) levels. Additionally, transcriptome sequencing was performed on 18 skin samples to identify genes associated with THFD. Results The unique structure of the hair follicle group leads to an uneven distribution of hair follicles, resulting variation in THFD at the local-site. THFD exhibited a gradient pattern throughout the body, characterized by elevated values in the scapular region and decreased values in the abdominal region. THFD showed uneven distribution across the whole-body, with a consistent pattern observed in Inner Mongolia cashmere goats, Dazu black goats and their F1 hybrids (DBG♂ × IMCG♀). Through the integration of differential gene expression analysis, trend analysis, weighted correlation network analysis, Venn analysis, and literature review, four core genes ( GJA1 , DSP , CDH3 , and PER1 ) were identified. These genes showed high and specific expression in skin tissue and demonstrated a significant response to changes in THFD. Conclusion This study thoroughly characterized the spatial variation of THFD at the local-site, body-side, and whole-body levels in order to gain a better understanding of genetic characterization, associated genes and spatial variation. Additionally, we have identified four genes that are associated with THFD. These findings provide an important reference for the subsequent development and utilization of THFD genes in cashmere goats.
