MICROBIAL 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 کاملsiderophore from Mycobacterium smegmatis
The extracellular siderophore from Mycobacterium smegmatis, exochelin MS, was isolated from iron-deficiently grown cultures and purified to > 98 % by a combination of ion-exchange chromatography and h.p.l.c. The material is unextractable into organic solvents, is basic (pI = 9.3-9.5), has a Amax. at 420 nm and a probable K. for Fe3+ of between 1025 and 1030. Its structure has been determined by...
متن کاملAmylooligosaccharides from Mycobacterium smegmatis.
In early stationary phase of growth, Mycobacterium smegmatis cultures accumulate amylooligosaccharides (alpha 1 leads to 4-glucooligosaccharides) up to the undecasaccharide. Although M. smegmatis also makes an acylated polymethylpolysaccharide that is predominantly and alpha 1 leads to 4-glucan, we conclude that these oligosaccharides are precursors of glycogen rather than lopopolysaccharide.

متن کاملTranscriptome Landscape of Mycobacterium smegmatis
The non-pathogenic bacterium Mycobacterium smegmatis mc2155 has been widely used as a model organism in mycobacterial research, yet a detailed study about its transcription landscape remains to be established. Here we report the transcriptome, expression profiles and transcriptional structures through growth-phase-dependent RNA sequencing (RNA-seq) as well as other related experiments. We found...
