Single Cell Protein production by Probiotics Grown on Fruit Waste
Journal Title: International Journal of Advanced Biotechnology and Research. - Year 2016, Vol 7, Issue 1
Abstract
ABSTRACT: The increasing demand for food production leads to a wide gap in-between demand and supply. To bridge this gap the microbial biomass i.e. single cell protein (SCP) can be considered as an alternative to conventional source of food or feed. In this present work we have attempted for production of SCP by using the probiotics such as Lactobacillus acidophilus, Streptococcus thermophilus and Bacillus coagulans as they don’t cause any harm if ingested. These probiotics were grown in medium containing 5g/l (NH2)2SO4, 1g/l MgSO4.7H2O, 0.5g/l NaCl, 0.1g/l CaCl2 and fruit waste as a carbon source and incubated for 7 days. The fruit wastes of Custard apple, Watermelon and Sweet lime were used in this study. The media was then optimized for carbon sources, pH and temperature. The produced biomass was then harvested by filtration. The harvested biomass was analyzed for crude protein by Kjendhal method and protein recovery from fruit waste was calculated. We obtained maximum biomass yield by S. thermophilus where as custard apple was found to serve as best carbon source. The protein recovery by S. thermophilus was more (11.15 g/100g waste) as compared to other two probiotics. The present findings reveal that custard apple waste can be used as an effective alternative carbon source for SCP production and probiotic S. thermophilus was found to be best among used probiotics to recover more protein from waste.
