چکیده

In biotransformations carried out under similar conditions enzymatic systems from carrot (Daucus carota L.), celeriac (Apium graveolens L. var. rapaceum) and horse-radish (Armoracia lapathifolia Gilib.) hydrolyzed the ester bonds of acetates of phenols or alicyclic alcohols. Nevertheless, methyl esters of aromatic acids did not undergo hydrolysis. Alcohols were oxidized to ketones in a reversible reaction.

Interspecies variation in the hepatic biotransformation of zearalenone: Evidence for bio-inactivation of mycoestrogen zearalenone in sturgeon fish

Zearalenone (ZEA) as mycoestrogen is found in human foods and animal feeds. Its estrogenic potency depends on its biotransformation fate. The hepatic biotransformation of ZEA in two species of sturgeon fish (Acipenser persicus and Huso huso) was investigated. ZEA was incubated with the hepatic microsomal and post-mitochondrial sub-fractions in the presence of NADPH and the metabolites were dete...

Oxidation of Meloxicam by Streptomyces griseus

The aim of the present investigation was to biotransform the anti-inflammatory compound meloxicam by enzymes present in whole cells of five actinomycete cultures to produce novel bioactive derivatives. Among the actinomycetes screened, Streptomyces griseus NCIM 2622 was found to possess the enzyme system(s) that oxidize meloxicam into two metabolites whereas that present in S. griseus NCIM 2623...

The Conversion of Shikimic Acid to Anthranilic Acid by Extracts of Neurospora Crassa.

The role of shikimic acid as a common intermediate in the synthesis of phenylalanine, tyrosine, tryptophan, and p-aminobenzoic acid has been recognized for some time (l-3). The enzymes which catalyze the synthesis of shikimic acid from intermediates of carbohydrate metabolism have been observed in extracts of bacteria (4-6) as well as Neurospora crassa (7). On the other hand, the reactions lead...
