List of technologies:
Eco-Friendly Handmade Paper Production Paper is a fundamental part of most aspects of society; world-wide a total of approximately 300 million tons of paper are produced each day and approximately 90% of this paper is produced from mature pulp wood. In addition the demand of paper is expected to increase. Today the finest of papers are produced all over the world. But one dismaying fact is that millions of trees are fell in a day to make paper. Increased demands of paper production and limited wood resources have directed researchers to look for appropriate additional resources of non-wood materials for pulp and paper manufacturing. Several kinds of non-wood lingo cellulosic by-products of agricultural cultivation have been investigated by the researchers. Papers made by conventional method causes high pollution problem. This disastrous effect will affect our world's beautiful ecosystem. Papers are made from tree free materials like silk cotton, cotton, bagasse, banana fibres, mat grass, kenaf , agave and jute waste. Microbial pulping is pollution free technology. Eco-friendly paper production is alkali-free and non- polluting process that has advantages over conventional process. This ecofriendly method saves our mother earth from global warming. This area presently focuses on making paper from agave and kenaf plants treated with different fungal isolates such as Trichoderma sp., Rhizopus sp. etc. The fungi were isolated from soil samples and plated on Potato Dextrose Agar medium plates. These were used in bleaching of fibers obtained from banana pseudostem and kenaf plant. The percentage of cellulose, lignin and hemicellulose were analysed before and after microbial treatments. Bio-Fertilizers and Bio-Pesticides The term biofertilizers or `microbial inoculants' can be generally defined as a preparation containing live or latent cells of efficient strains of nitrogen fixing, phosphate solubilising or cellulytic microorganisms used for application of seed, soil or composting with the objective of increasing the number of such microorganisms and accelerate certain microbial process to augment the extent of the availability of nutrients in a form which can be easily assimilated by plant. As a result of the studies conducted on Biofertilizers and Biopesticides, more bacterial isolates were isolated and identified using different biochemical tests. The isolated strains were then checked for their bio-controlling and growth promoting efficiency and phosphate solubilizing capacity. Potato dextrose agar was used for fungal isolation and lactophenol cotton blue test performed for morphological identification. A combination of Pseudomonas fluorescence and Trichoderma viride cultures were made to check the biocontrol efficiency of bacterial-fungal consortia against paddy pests. Among the different low cost media tried, CSL-V, milk water, rice water and combination of milk and rice water offered better growth than other trials. Field trials were done on paddy, tomato and papaya and against Pythium sp. Talcum powder formulations were developed with a combination of four microbial species such as Trichoderma viride, Paecilomyce lilacinus, Pseudomonas putida and Pseudomonas fluorescence.
Promotion of domestication and cultivation of promising medicinal plants has been carried out at MCRC through DST-Core support programme. A variety of medicinal plants such as Boerhaavia diffusa, Andrographis paniculata, Coleus sp., Aloe vera, Ocimum sanctum, Costus spicatus, Spilanthus calva, Gymnema Sylvestre and Justicia gendarussa were established in field conditions using organic manures and their growth and yield parameters evaluated. A model medicinal plant nursery garden has been developed in the campus for the maintenance of about 30 different medicinal plants. Dissemination of edible mushroom cultivation technology (Oyster) to rural population including marginalized farmers and women in Thiruvedanthai , Kancheepuram district, and Thiruvarur districts Tamil Nadu. The efficacy of different unexplored agricultural residues as raw materials for mushroom cultivation was developed as cultivation packages for rural livelihood. Though mushrooms have high protein content, they are still not popular in India, and DST core support is making efforts to create awareness through various training programs and workshops
