Optimization of macronutrient kinetics for biomass production in Nostoc calcicola

摘要

Addition of nutrients is a promising strategy for maximizing growth of Nostoc calcicola.To assess the feasibility of Allen and Anion's (AA) media addition to increase the biomass productivity, (0, 2.5, 5, 7.5 ml of 1 Ox media concentrate - MC) was added to aerated culture every six days, in two separate conditions i.e., single harvest (SH) and continuous harvest (CH) after 15th day.Results show that with addition of 5 ml of MC produced maximum amount of biomass is 1.32 g/L and 2.88 g/L for Sh and CH respectively.These results show that with addition of 5 ml of MC to an aerated culture every six days with continuous biomass harvesting leads to maximum growth of Nostoc calcicola @25°C
