标题:Synthesis Of 9α-Hydroxysteroids By A Rhodococcus Sp.
摘要:9 Alpha-Hydroxylation Of Delta 5-3 Beta-Hydroxysteroids (Of Androstane,Pregnane,24-Nor-And 21,24-Bisnorcholane Groups) Was Carried Out By A Rhodococcus Sp.,Isolated From A Petroleum-Containing Soil Sample. A Large Number Of The Investigated Steroids Was Transformed Into 9 Alpha-Hydroxy-Delta 4-3-Ketones In Satisfactory Yields (50-90%) At High Initial Concentrations Of The Substrates (0.5-5.0 G/l). The Influence Of Some Structural Features Of The Steroid Molecule On The Progress And Effectiveness Of The Microbial Transformation Was Also Shown.
