Synthesis of homoveratric acid-imprinted polymers and their evaluation as selective separation materials.
A bulk polymerization method was used to easily and efficiently prepare homoveratric acid (3,4-dimethoxyphenylacetic acid)-imprinted polymers from eight basic monomers: 2-vinylpyridine, 4-vinylpyridin...Read More
The oxidizing ability of a nitrifying consortium exposed to p-cresol (25 mg CL(-1)) was evaluated in batch cultures. Biotransformation of the phenolic compound was investigated by identifying the diff...Read More
Methanotrophs expressing soluble methane monooxygenase (sMMO) may find use in a variety of industrial applications. However, sMMO expression is strongly inhibited by copper, and the growth rate may be...Read More
Soluble methane monooxygenase (sMMO) can degrade many chlorinated and aromatic pollutants. It is produced by certain methanotrophs such as Methylosinus trichosporium when grown on methane under copper...Read More
Halogenated fumigants have been used extensively in production agriculture to control soilborne pests. These types of pesticides are highly volatile and are prone to affect air quality and imperil pub...Read More
To observe the effect of acryl thiourea, an inhibitor of phenol oxidase, on pathological changes in the liver of mice infected with Schistosoma japonicum....Read More
Influence of sediment and pore-water composition on nitrite accumulation in a nitrate-perfused freshwater sediment.
Anaerobic nitrate consumption was accompanied by the accumulation of nitrite in the range of 3-52 micromoll(-1) in laboratory sediment cores continuously perfused with nitrate from below. Highest inte...Read More
A screening method for nitrification-inhibition determination has been evaluated at two laboratories, one in Sweden and one in Spain. Allyl-thiourea (ATU), methanol, chromium and zinc were used as ref...Read More
Cloned luciferase-encoding operons were transferred by conjugation to a natural isolate of the ammonia-oxidizing bacterial strain Nitrosomonas sp. RST41-3, thereby establishing conjugation as a tool f...Read More
A bioluminescence assay using Nitrosomonas europaea for rapid and sensitive detection of nitrification inhibitors.
An expression vector for the luxAB genes, derived from Vibrio harveyi, was introduced into Nitrosomonas europaea. Although the recombinant strain produced bioluminescence due to the expression of the ...Read More
It has been found that treatment of mice infected with Schistosoma mansoni with thiosinamine for five days had a significant effect on the formation of normal egg-shells within the ootype of female wo...Read More
Tyrosinase (TYR) was thought to play a critical role during trematode egg production. In this study, we analyzed two genes (SjTYR1 and SjTYR2), derived from Schistosoma japonicum genome databases, whi...Read More
Impact of protozoan grazing on nitrification and the ammonia- and nitrite-oxidizing bacterial communities in activated sludge.
In activated sludge, protozoa feed on free-swimming bacteria and suspended particles, inducing flocculation and increasing the turnover rate of nutrients. In this study, the effect of protozoan grazin...Read More
The effects of three metabolic inhibitors (acetylene, methanol, and allylthiourea [ATU]) on the pathways of N2 production were investigated by using short anoxic incubations of marine sediment with a ...Read More
Inhibition of membrane-bound methane monooxygenase and ammonia monooxygenase by diphenyliodonium: implications for electron transfer.
Diphenyliodonium (DPI) is known to irreversibly inactivate flavoproteins. We have found that DPI inhibits both membrane-bound methane monooxygenase (pMMO) from Methylococcus capsulatus and ammonia mon...Read More
To elucidate the nature of negative and positive phases of background delta-waves (BDW), their interaction with evoked potentials was studied in the rabbit visual cortex. BDW appeared after injection ...Read More
The effect of thiosulphate and other inhibitors of autotrophic nitrification on heterotrophic nitrifiers.
It has been found that heterotrophic nitrification by Thiosphaera pantotropha can be inhibited by thiosulphate in batch and chemostat cultures. Allythiourea and nitrapyrin, both classically considered...Read More
Microbial transformation of pharmaceuticals naproxen, bisoprolol, and diclofenac in aerobic and anaerobic environments.
Although biotransformation is generally considered to be the main process by which to remove pharmaceuticals, both in sewage treatment plants and in aquatic environments, quantitative information on s...Read More
