No degradation of γ-hexachlorocyclohexane occurred in the medium inoculated with sterilized sugarcane rhizosphere soil suspension. During degradation, about 40% of the14C from the ring-14C-γ-hexachlorocyclohexane was released as CO2 indicating ring cleavage. A bacterium,Pseudomonas sp., isolated from hexachlorocyclohexane-treated sugarcane rhizosphere soil readily degraded γ-hexachlorocyclohexane added to a mineral salts medium as a sole source of carbon under aerobic conditions. An increase in temperature from 20-25 and 30°C progressively increased the degradation of α- and γ-hexachlorocyclohexane by rhizosphere soil.
