The authors report here the preliminary results of the study using monitored natural attenuation (MNA), referred to as intrinsic remediation, as an in situ treatment method in an abandoned gold mining site in Kolar Gold Fields, Karnataka. The area is called the Kolar schist belt of south India, well-known for its gold deposits which have been mined systematically for over several decades.

Polluting industries along a 500-km stretch of the Ganga between Kannauj and Varanasi might soon face the axe.

Dyes present in the effluent of textile industries are recalcitrant molecules difficult to be degraded biologically. In this study we used Pseudomonas fluorescens to degrade Direct Orange - 102 dye. Pseudomonas fluorescens NCIM 2100 was obtained from National Chemical Laboratory, Pune, India, that was adapted to grow on Direct Orange - 102.

The potential of Vigna subterranean commonly called Bambara beans for phytoextraction of copper in a crude oil contaminated soil was investigated. The contamination levels of crude oil in the soil for this pot experiment were 2, 4, 6, 8 and 10% (w/v). Amendments were added to increase the uptake and translocation of metal to aerial biomass.

Imagine the most sophisticated engineering feat you can think of, and you might not consider a living cell. And yet cells are fabulously sophisticated, able to produce all the proteins, tissues, and biological circuits that give rise to life. Scientists have spent hundreds of years just trying to understand cells and to work with them as they were created by nature.

Role of marine bacteria viz. Marinococcus albus, Methylobacterium mesophilicum and Nocardia otitidiscaviarum in bioremediation of crude oil contaminated Alang sea coast has been evaluated in the present study. Optimum concentrations of inorganic nutrients N, P & K as urea, super phos and potash fertilizers respectively on growth and degradation has been determined.

This review provides applications of conventional and non-conventional adsorbents for removal of pesticides from waste-waters. The data presented are mainly based on laboratory studies and show potential advantages for treatment of pesticides bearing wastewater by various adsorbents.

This article describes biotechnological modes, updated in terms of environmental remediation while exploiting natural resources. Modern biotechnology embraces not only the principles of using various organisms but also the techniques of doing so. Both the aspects are dealt with in detail.

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.
