  Biohydrogen is a clean and environmental friendly renewable energy source. It only produces water after combustion. Anaerobic fermentation process is one of the best suitable technique for the biohydrogen production from industrial wastes. In this study with the consortium of biohydrogen producing bacteria B1 and B4 at the pH 5 and temperature 70°C, the effect of different concentration of ferrous and nitrate ions in the production of biohydrogen from dairy effluent was analyzed. Maximum biohydrogen production at the concentration of 100 mg L-1 of ferrous ion during 24 h HRT (Hydraulic Retention Time) was 55 mL with HPR (Hydrogen Production Rate) of 5.729 mL L-1 h-1 and during 48 h HRT 85 mL of biohydrogen was produced with the HPR of 4.427 mL L-1 h-1. This process has been found to be an efficient method for the treatment of effluent in different pollution parameters after this fermentative biohydrogen production.

  Preservation of commercial and research important fungi for long time period is a very tedious job. Mostly cryopreservation technique in liquid nitrogen is used for long term preservation. In this work 15 different species of commercial and research important fungi are preserved at 4°C in different concentration of glycerol using two different methods (Slant culture and Slice cut method). In slant culture method at 50% of glycerol, 100 and 86.66% of fungi are viable upto 24 and 30 months of preservation, respectively. In slice cut culture method 100% of fungi are having regeneration capacity upto 24 months of preservation. This study help to preserve the fungi with easy and low cost for long term period at 4°C under refrigerator.
