The expansion of citrus processing plants and development in citrus technology brought about problems of disposal of the waste remaining after extraction of juice or making other products from fruit. Recycling of wastes has not only become as necessity but also a challenge in these days of energy crisis. In the present work attempts had been made for the production of single cell protein in the form of microbial biomass utilizing agricultural waste i.e. orange peels under laboratory conditions. Bacterium Pseudomonas fluorescence, fungus Aspergillus oryzae and yeast Saccharomyces cerevisiae were used for checking their ability to grow on citrus waste. Saccharomyces cerevisiae gave maximum biomass so, utilized for further study. 10% concentration of citrus waste gave maximum production of biomass under submerged conditions i.e. 3200mg/lit and 1600mg/lit of protein. Addition of glucose supplement increased the biomass production and 0.5% sugar gave maximum yield i.e. 5700mg/lit and 2800mg/lit of protein whereas further addition of glucose decreased the biomass production. Similarly, addition of pectin also positively influenced the growth of Saccharomyces cerevisiae at 0.5% concentration where maximum biomass was obtained i.e. 9800mg/lit or protein.
