SCREENING METHOD OF HIGHLY AFFINITIVE MICROORGANISM AND HIGHLY PHENOL-AFFINITIVE MICROORGANISM

摘要

PURPOSE:To conduct efficient screening of highly affinitive microorganisms having a carbon compound decomposition activity satisfactory even in the low concentration areas by gradually increasing the concentration of the carbon compound in the culture medium to be fed till reaching a certain level. CONSTITUTION:As single carbon source in the culture medium to be fed, a carbon compound such as phenol, benzene or the like is added to increase the concentration gradually till a certain level to effect screening of the microorganisms having high potency of biodegradation of the carbon compound as a substrate. Accordingly to this process, a microorganism having a high affinity to phenol originating from Alcaligenes-sp. R2 strain (FERM-P-13805) is obtained.
