The paddy rhizosphere soil sample was collected from 10 different locations and the Pseudomonas fluorescens & Bacillus subtilis isolates were characterized. The ten P. fluorescens & B. subtilis isolates were tested for their efficiency of IAA production, Gibberellic acid, Siderophore production and Phosphate solubilization. Among the various isolated of P. fluorescens & B. subtilis, the isolate PF-8 and BS-8 was selected as a more efficient strain and that strains were used for the Mutagenesis studies. The EMS mutated P. fluorescens & B. subtilis showed more plant growth promoting substances...

The Sugar mill effluent was collected in the present research and used for the cultivation of Spirulina platensis. The physico-chemical characteristics of the Sugar mill effluent were analyzed. The Blue Green Algae Spirulina platensis was cultivated in conical flask containing Zarrouks medium with three different concentrations of Sugar mill effluent (50 ml, 75 ml and 100 ml/lt). The Direct microscopic count, optical density and dry biomass of S. platensis was high in SP4 followed by SP3 and SP2. The least microscopic count was recorded in SP1. Phycocyanin was extracted from harvested S....

Amino peptidases have many important commercial applications. The food industry uses them for debittesing and improving the functional properties of protein products and the flavor development in cheese. In pharmaceutical industry inhibitors developing against this enzyme find application as drug. Amino peptidase is also used for peptide sequencing and in processing of recombinant proteins. The different species of fungi were isolated from marine soil sample and the Aspergillus flavus was dominantly present. The amino peptidase activity measured at different pH and temperatures was found to...

Spirulina platensis was cultivated by inoculated in Zarrouk's medium and Zarrouk's medium with four different supplementation such as Multivitamin tablet, tender coconut water, cow dung and cow urine in four different concentration. The inoculated medium was subjected to physiological conditions by providing aeration and artificial light source. The growth determination was done by Direct Microscopic Count, Optical density and Dry mass. At 20th day of incubation, the Spirulina were harvested and the C-Phycocyanin was extracted by alternative cycles of freezing, thawing and centrifugation. The...
