Case History:

Mangrove forest ecosystems are threatened by direct impacts such as cutting and pollution due to agricultural, industrialization and urbanization activities. Mangrove forests are often regarded as unpleasant environments with little intrinsic value. Mangrove forests perform valued regional and site-specific functions. Mangrove species can take up excessive nutrients and also play a crucial role in creating a favourable environment for a variety of chemical, biological and physical processes that contribute to the inorganic removal and degradation of organic compounds.

Several mechanisms are developed by the microorganisms to tolerate few high concentrations of heavy metals. One of these mechanisms dependent upon anabolic and catabolic energy of microorganisms is the bioaccumulation of heavy metals. In present work, approximately four varieties of bacteria have been isolated from the ash dyke sample of four thermal power plants of Chhattisgarh, i.e., Bharat Aluminium Company (BALCO), Chhattisgarh State Electricity Board (CSEB), Korba, Thermal Power Cooperation (NTPC), Bilaspur and KSK Akaltara, Chattisgarh.

Polycyclic aromatic hydrocarbon (PAH)-degrading bacteria were isolated from prolong contaminated Amalakhadi sediment and crude oil polluted soil Telva, near Ankleshwar Gujarat India. Organisms were treated with two-model PAHs compound Anthracene (ANT), and Pyrene (PYR) as the sole source of carbon and energy. Identification of the isolates was carried out based on their morphological and partial 16S rRNA gene sequences, which revealed that the isolates belong to two main bacterial groups: gram-negative pseudomonas indoxyladons and gram-positive, spore-forming group, Bacillus benzoevorans.

Activated carbon was prepared from Behda (BEAC), Anjan (AAC), Chinch (CAC), and Bakam Neem (BNAC) leaves. The effects of various parameters such as initial metal concentration, particle size, pH and contact time for the adsorption of Cu (II) on BEAC, AAC, CAC and BNAC were investigated. The amount of adsorbent increased the percentage of metal removal increased accordingly. The optimum pH for the Cu (II) absorption was 7.0 except BEAC. The equilibrium data fit well with both Langmuir and Freundlich models of adsorption.

Domiasiat (25°30′N 91°30′E) located in the west Khasi hill district of Meghalaya in northeast India is one of the largest sandstone-type uranium (U) ore deposit in India containing 9.22 million tonnes of ore reserves with an average ore grade of around 0.1 % U3O8. This geographically distinct U deposit of Domiasiat is un-mined and harbours diverse group of bacteria surviving the stressful environmental conditions prevalent in the ore deposit. Studies show that the diverse bacteria belonged to 10 different bacterial groups with occurrence of some previously uncharacterized bacteria.

It is well understood that the evolution of the Earth with its plurality of environmental elements is the resultant productmix of geological and biological processes coupled together. Any natural environment reflects an interactive dynamics
of mineralogy–biology–chemistry. Consequently, with temporal evolution, the milieu tends to change. Aquifers in the

The festival of ‘Holi’ is proving to be an environmental risk due to the toxic colors used during the celebrations. Unlimited and uncontrolled use of such dyes can lead to grave consequences in terms of human health and ecological balance. These colors are highly structured polymers and are very difficult to decompose biologically. This study was taken up with an initiative to determine the extent of effects that the ‘Holi’ colors have on water and soil, respectively. The bacteria inhabiting these contaminated water and soil samples were isolated for biochemical analyses.
