Degradation of Disodium Terephthalate by Alkaliphilic Bacterium Strain GS-1

Abstract

An alkaliphilic bacterium strain GS-1 assimilating disodium terephthalate as the sole carbon and energy sources was isolated from soil. The strain GS-1 degraded 19.3mM(1M=mol/dm³) of disodium terephtalate in 168h at alkaline condition(pH10) with the growth. The cultures showed degradation lag phase of 72h before growth commenced. The greatest degradation occurred between 72 and 100h. The maximum degradation rate was 0.46mM/h. The doubling time was 9.3h.
