The bacterial diversity in a tropical soil experimentally polluted with crude oil during a 57 days bioremediation was investigated in five 1 m2 plots using total culturable hydrocarbon utilizing bacteria, heterotrophic bacteria and gas chromatographic analyses. Four out of the five experimental plots received each 4 L of Bonny light crude oil while three treatment plots received 3 kg of NPK, urea fertilizers or poultry droppings with periodic tilling. Two plots, oil-contaminated and pristine served as controls.

In the present study, the possibility of biodegrading the dechlorinated product of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(chlorophenyl) ethylene (DDE) and structurally related compound 1,1-dichloro-2,2-bis(chlorophenyl)-ethane (DDD) under aerobic conditions was examined.

The ability for heavy metals removal by C. odorata and V. zizanioides grown on contaminated soil and synthetic contaminated soil in experimental pots was investigated. Both contaminated and uncontaminated soils, for preparing the synthetic contaminated soil in this study, were obtained from Mae Sot district, Tak province.

The ability of Calocybe indica, to degrade lindane and imidacloprid was studied in a sandy loam soil. C. indica grew well in lindane and imidacloprid fortified soil, but growth rate decreased with increase in concentration of the insecticides.

A seven year remediation program for the hazardous waste treatment site situated at the Ramat Hovav Industrial Zone in Israel begins.

This publication details the successful story of participatory conservation of Whale Shark (Rhincodon typus) in Gujarat lead by WTI.

Cr (VI) (Chromate) is a toxic, soluble environmental contaminant. Bacteria can reduce chromate to the insoluble and less toxic Cr (III), and thus chromate bioremediation is of interest.

The present work relates to isolation of promising Pseudomonas strain from the oil contaminated sites in service stations, Namakkal and then collecting a saline tolerant Pseudomonas strain from the coastal saline region of Rameswaram. These bacterial strains have been optimally characterized with regard to biodegradation of oil.

The biological agents viz. fungi and bacteria (Pseudomonas sp.) were tried to develop a suitable technology for purification of industrial effluent. Pure culture of Pseudomonas sp. and locally isolated fungi sp. from mix industrial effluents were utilized in the study. The laboratory study was carried out to know the tolerance of Pseudomonas sp. against different heavy metals concentration.

Phytoremediation, the use of plants and their associated microbes for environmental cleanup, has gained acceptance in the past 10 years as a cost-effective, noninvasive alternative or complementary technology for engineering-based remediation methods. Plants can be used for pollutant stabilization, extraction, degradation or volatilization.
