Increased mutagenesis mediated by cloned plasmid CAM-OCT genes: potential for expanding substrate ranges of Pseudomonas spp
Article Abstract:
The cloning of Pseudomonas plasmid CAM-OCT DNA encoding a DNA repair gene produces strains able to use ethyl lactate or 3-methyl-3-buten-1-ol as the carbon source after UV irradiation. The cloning produces a broad-host-range vector pVK100. The strains consuming ethyl lactate produce an unique intracellular hydrolase. The CAM-OCT genes having extended substrate ranges can oxygenize alkenes to epoxides, which act as building blocks for the synthesis of pharmaceutical compounds.

Effect of environmental factors on the relationship between concentrations of Coprostanol and fecal indicator bacteria in tropical (Mekong Delta) and temperate (Tokyo) freshwaters
Article Abstract:
All around Asia sewage pollution poses a health hazard to people living near waterways or rivers but very little studies are conducted to learn about the ill effects and counter measures against this pollution. Studies conducted show that E. coli is a specific indicator of fecal contamination but a more reliable indicator of water pollution needs to be developed.

Estimation of the yield coefficient of Pseudomonas sp. strain DP-4 with a low substrate (2,4-dichlorophenol [DCP]) concentration in a mineral medium from which uncharacterized organic compounds were eliminated by a non-DCP-degrading organism
Article Abstract:
Results show that in Pseudomonas sp. strain DP-4 the biodegradation of low level chemicals is influenced by the chemicals present at high concentration levels. Data indicate that the yield coefficient of 2,4-dichlorophenol is as an index of the extent of degradation.
