Degradation of 17beta-estradiol in aqueous solution by ozonation in the presence of manganese(II) and oxalic acid.
Natural estrogens, such as 17beta-estradiol (E2), are the main substances responsible for estrogenic activity found in domestic sewage. In the work described herein, the degradation of E2 has been inv...Read More
Cadmium and manganese accumulation in Phytolacca americana L. and the roles of non-protein thiols and organic acids.
Phytolacca americana L. can accumulate large amounts of heavy metals in its aerial tissues, especially cadmium (Cd) and manganese (Mn). It has great potential for use in phytoextraction of metals from...Read More
Influence of oxalic and malic acids in chickpea leaf exudates on the biological activity of CryIAc towards Helicoverpa armigera.

Manganese(III) geocomponents are commonly found in the soil environment, yet their roles in many biogeochemical processes remain unknown. In this study, we demonstrated that Mn(III) generated from the...Read More
Changes in pH and organic acids in mucilage of Eriophorum angustifolium roots after exposure to elevated concentrations of toxic elements.
The presence of Eriophorum angustifolium in mine tailings of pyrite maintains a neutral pH, despite weathering, thus lowering the release of toxic elements into acid mine drainage water. We investigat...Read More
Identification of a Transcription Factor Controlling pH-Dependent Organic Acid Response in Aspergillus niger.
Acid formation in Aspergillus niger is known to be subjected to tight regulation, and the acid production profiles are fine-tuned to respond to the ambient pH. Based on transcriptome data, putative tr...Read More
A comparison of glucose concentration in paired specimens collected in serum separator and fluoride/potassium oxalate blood collection tubes under survey 'field' conditions.
There are no direct comparisons of blood glucose values in samples collected with barrier serum tubes (SST?) and NaF/potassium oxalate (NaF/KOx) plasma tubes. Collection of samples in SST? tubes can o...Read More
What do results of common sequential fractionation and single-step extractions tell us about P binding with Fe and Al compounds in non-calcareous sediments?
Correct identification of P forms together with their main Fe and Al binding partners in non-calcareous sediments is of crucial importance for evaluation of P cycling in water bodies. In this paper, w...Read More
