Environment is a highly complex and varied issue and as a consequence, an extremely diverse projects have been taken up by the Department of Biotechnology.
During the 11th Five Year Plan (2007 to 2012), a total of 112 R&D projects were supported by the DBT in these areas and generated the following scientific leads/ technologies:
Five green water technologies for coastal aquaculture
Three technologies for technological improvement in pulp and paper effluent treatment
Developed protocol for application of biosurfactant in bioremediation and in-situ production of surface active molecules to improve the bioavailability
Developed bioplastics by reinforcing waste plant material into low density polyethylene via compressio moulding and developed method for size reduction of natural fibres for using as reinforcement in plastics
Developed a technology for sensing arsenic by arsenic-resistant microbes and cell free extract of the microbes
The PCR-based technique developed allowed accurate discrimination between the commonly prevalent trematode species
Technology developed for tannery effluent for removal for chromium by fungus (Aspergillus niger FIST1) and bacterium (Serratia mercascens) and degradation of biotic, pentachlorophenol by stable bacterial consortium-chromium cake
Technology developed for preparation leather by enzyme technology (protease and lipase) and chromium cake for tanning leather
Technology developed for pulp and paper mill effluent for removal of colour by fungus (Cryptococcus albidus), and degradation of chlorinated phenol by alkalophilic bacterial consortium
Preparation of pulp and paper after treatment by micro-organism, bio-pulping and bio-leaching
Production of bio-ethanol from bagasse of pulp and paper mill effluent
Site specific restoration technologies have been developed and transferred for restoration of mined out areas by stakeholders.
Isolation of high molecular weight metagenomic DNA from a highly polluted soil samples
Metagenome sequencing (pyrosequencing) of a polluted soil sample to get the insight into the microbial community prevailing in the niche and to know the catabolic repertory present in the community.
