Role of heterotrophic bacteria in complete mineralization of trichloroethylene by Methylocystis sp. strain M
Article Abstract:
Trichloroethylene (TCE) can be degraded by a methanotrophic mixed culture, termed MU-81. Among the TCE-degrading species in this culture is Methylocystis sp. strain M. The profiles of TCE-degradation products by strain M and MU-81 were compared. The results showed that stain M could only partially convert TCE to carbon dioxide, while the mixed culture could degrade TCE more completely. This was attributed to the presence of Xanthobacter autotrophicus in the MU-81 culture. This indicates that heterotrophic bacteria are also essential in the complete biodegradation of TCE by methanothrophs.

Isolation and characterization of cesium-accumulating bacteria
Article Abstract:
Two strains of bacteria, CS98 and CS402 of the genus Rhodococcus, with the ability to accumulate cesium, were isolated and characterized. The strains had a high-level ability to accumulate cesium, however, the accumulatedcesium was released after 24 and 48 hours for CS98 and CS402, respectively. CS98 and CS402 were able to concentrate cesium with maximum concentration factors of 3.5 x 10(super 4) and 3.6 x 10(super 3), respectively. It is expected that the two strains can be used for the removal and monitoring of radioactive cesium in natural environments.

Aerobic degradation of 1,1,1-trichloroethane by Mycobacterium spp. isolated from soil
Article Abstract:
Research was conducted to examine the degradation of 1,1,1-trichloroethane (TCA) by two strains of Mycobacterium bacteria under aerobic conditions. The data indicate that the bacteria are capable of mediating degradation of high concentrations of TCA in the soil.
