The biotransformations of testosterone, epiandrosterone, progesterone and pregnenolone byAspergillus terreusMRC 200365 for five days were described. The biotransformation of testosterone afforded testolactone. The biotransformation of epiandrosterone afforded 3β-hydroxy-17a-oxa-D-homo-5α-androstan-17-one. The biotransformation of progesterone afforded androst-4-ene-3,17-dione and testolactone. The biotransformation of pregnenolone afforded 3β-hydroxy-17a-oxa-D-homoandrost-5-en-17-one and testolactone.

Abstract:

Mycotoxins are toxic fungal secondary metabolites that pose a major threat to the safety of food and feed. Mycotoxins are usually converted into less toxic or non-toxic metabolites through biotransformation that are often made by living organisms as well as the isolated enzymes. The conversions mainly include hydroxylation, oxidation, hydrogenation, de-epoxidation, methylation, glycosylation and glucuronidation, esterification, hydrolysis, sulfation, demethylation and deamination. Biotransformations of some notorious mycotoxins such as alfatoxins, alternariol, citrinin, fomannoxin, ochratoxins

ABSTRACTBiodiversities can differ substantially among different wastewater treatment plant (WWTP) communities. Whether differences in biodiversity translate into differences in the provision of particular ecosystem services, however, is under active debate. Theoretical considerations predict that WWTP communities with more biodiversity are more likely to contain strains that have positive effects on the rates of particular ecosystem functions, thus resulting in positive associations between those two variables. However, if WWTP communities were sufficiently biodiverse to nearly saturate the se
