MICROBIAL CHAIN DEGRADATION OF CHOLESTEROL BY ARTHROB ACTER SIMPLEX
نویسندگان: ثبت نشده
چکیده مقاله:
Because of the importance of microbial metabolites of cholesterol as precursors in the synthesis of steroidal drugs, we decided to study the ability of Arthrobacter simplex to degrade cholesterol. Arthrobacter simplex cleaves the side chain of cholesterol in the presence of 2,2'-dipyridyl and produces 4-androstene-3,17- dione (AD) and androsta- 1,4-diene-3,17-dione(ADD). Two other intermediates with intact side chain, 4-cholestene-3-one and cholesta- l,4-diene-3-one were also detected and purified in the culture of A. simplex

متن کاملMICROBIAL TRANSFORMATION OF CHOLESTEROL BY MYCOBACTERIUM SMEGMATIS
Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...

متن کاملCholesterol degradation by Gordonia cholesterolivorans.
This paper reports physiological and genetic data about the type strain Gordonia cholesterolivorans, a strain that is able to degrade steroid compounds containing a long carbon side chain such as cholesterol (C(27)), cholestenone (C(27)), ergosterol (C(28)), and stigmasterol (C(29)). The length of the carbon side chain appears to be of great importance for this bacterium, as the strain is unabl...
متن کاملMicrobial Degradation of Asphalt.
Organisms of the genera Pseudomonas, Chromobacterium, and Bacillus capable of degrading asphalt were isolated by enrichment cultures. The asphalt degradation by these organisms varied from 3 to 25% after incubation for 1 week. The effects of temperature, pH, and atmosphere of incubation on asphalt degradation were investigated and were shown to vary with different organisms on the same substrate.
