The department of Microbiology was established in 1964 with late Dr. S.R. Vyas as the founder Professor & Head, who laid solid foundation for the subsequent growth and development of the department.   Over the years, the department has made significant contribution in research, teaching and extension.  The department developed a solid state fermentation process for the production of citric acid from cane molasses using improved strains of Aspergillus niger.  Technology for the production of wine from locally grown grapes was developed by late Professor Vyas and the technical know-how for large scale production of wine was later given to Panipat Cooperative distillery, Panipat.  A process for the direct fermentation of sugarcane for alcohol production was developed.  Yeast strains have been developed for the production of ethanol from cane molasses which are being supplied to Indian distilleries.  Usefulness of organic manures in maintaining soil organic matter status and their role in pollution abatement has been worked out.  Technology for enrichment of compost with (i) Azotobacterfor increased nitrogen content, (ii) rock phosphate for increased phosphate availability and (iii) urea for increased organic nitrogen content has been developed.  Use of neem cake in controlling nitrification and slow release of nitrogen from nitrogenous fertilizers has been worked out. Since the late sixties, the department has been in the forefront in carrying basic and applied research towards producing efficient rhizobial strains for chickpea, mungbean, urd bean, cowpea, berseem soybean and other legumes and Azotobacter for non-leguminous crops. Large scale production and distribution of biofertilizers to farmers has reached a maximum of 3,60,000 packets in the year 2011-12 .  The department was awarded National Productivity Council Award for 1985-86. Biofertilizers of phosphate solubilizing bacteria (PSB) and biocontrol inoculants of Gluconacetobacter are also being produced by the department. Molecular ecological studies of these microbes have also been carried out. Microbial parameters in the anaerobic digestion of organic wastes for biogas production have been studied.  Conditions for increasing biogas production in winter through recycling of spent slurry, and effective use of brackish water for biogas production have been worked out. Family size Janta biogas plant has been modified for solid state fermentation of cattle dung that has been tested all over India and has been found satisfactory.

     A) State funded projects:

  • Development and improvement of microorganisms for use in agriculture, industry and environment

  • "Co-composting of rice straw with different agro-industrial wastes and its enrichment for crop production"

            B)  ICAR funded projects:

  • ICAR Network on biofertilizers

  • AICRP on Renewable sources of energy for agriculture and agro based industries (Bioconversion technology)

       C)  Other agency projects :

  • Molecular Characterization of functional and uncultured bacterial community in semi-arid zone of Haryana

Research

  • Effective microbial strains of RhizobiumAzotobacterAzospirillum and Gluconacetobacter and phosphate solubilizing bacteria have been developed for use in bioinoculant production. These bioinoculants are compatible with recommended doses of insecticides and pesticides for use in crop production.

  • Department of Microbiology has developed liquid based biofertilizer production technology to supply biofertilizers to farmers and other allied agencies. Bioinoculants like RhizoteekaAzoteekaPhosphoteeka  andBioteeka are being produced for various crops.  The bioinoculants have shown positive response on legumes, cereals, millets, oilseeds, vegetables, cotton, forage crops and sugarcane under field conditions. More than 3 lacs liquid vials of 50ml each of different biofertilizers are produced for different crops every year to meet the demand of farmer and other farm agencies of Haryana, Punjab, Rajasthan and other states.

       

                     

  • A qualitative and quantitative method has been developed to assess the quality of biofertilizers using genetically marked strains, which can test the quality of biofertilizers in 1-2 h. The cost of assay is approximate Rs.100/assay.

  • Family size conventional Janta biogas plant (2 m3) for biogas production from undiluted cattle dung has been developed. Biogas production in modified biogas plant is 30-40% more than the conventional biogas plant and the cost of construction of this plant is similar to the cost of construction of conventional plant. The effluent slurry is easy to manage and serves as quality manure.

 

            

 

  • The supplementation of spent mushroom substrate @2% to cattle dung increase the biogas production to the tune of 20 to 30 % particularly in winter. 

  • Salinity tolerant strain of Azotobacter chrooococcum ST-3 has been developed and  its  inoculation  increases  the yield of wheat by 2 to 5 % over uninoculated control under field conditions.

  • Technology has been developed for production of N, P, K enriched compost using crop residues and microbial inoculants. The crop yield on application of rice straw compost @5t/ha alongwith 50% RDF in scented rice under field conditions was at par with 100% RDF.

  • Biocontrol agents capable of inhibiting plant pathogens and killing termites have been isolated. The application of these biocontrol agents under laboratory and pot house conditions have resulted in 10-12% disease control over fungicide alone.

  • Studies on long term impact of zero tillage indicated no adverse effect on soil microbial population in different cropping systems.

  • Laboratory protocol for production of ethanol from rice straw has been developed.

  • Pyrene degrading bacteria isolated from PAH contaminated soils decreased the pyrene level of soil significantly hence can be used for decontamination of hazardous contaminated soils.

  • Microbial map of nitrogen fixing bacteria has been prepared from soil samples collected from different arid and semi arid zones of Haryana.
