Abstract
|
|
|
Seven strains of methanol assimilating yeasts were isolated from soil enriched with tetracycline. Among them two better growing strains were selected and partially identified as species belonging to genus Candida. The both Candida 1-B and 25-A, grew best under conditions of pH 5.0 and 28℃.
The optimal methol concentration in the medium was found to be 1%, Whereas the organism, could grow up to the 4% level.
Biotin was required by the organisms for growth and organic nitrogen sources raised the rate of growth. The yield of biomass per unit weight of consumed methanol after 96 hours were 36.9% by Candida 1-B and 39. 2% by 25-A.
