Bio-Efficiency of Paediococcus acidilactici ATCC 8042 for Recovery of Chitin and Carotenoids in the Fermentation of Shrimp Biowaste

Fermentation based on Lactic acid bacteria (LAB) hold great promise for the management of a shrimp biowaste. Although shrimp biowaste is usually dried on beaches it encourages not only environmental pollution but also reduces the recoverable components. Experiments were carried out to test the Paediococcus bacteria for recovery of chitin and carotenoids. Paediococcus acidilactici ATCC 8042 was found to be the efficient among three cultures. Optimized conditions were found to be 5% inoculum, 15% glucose, 2% NaCl and 72 h of incubation time at 37oC. The pH of 3.04 and total titrable acidity of 2.204 was achieved at the end of 72 h. The effect of fermentation shrimp biowaste by P. acidilactici ATCC 8042 on the production of chitin and recovery of carotenoids was studied. Deproteinization of 96.2% and demineralization of 71.9% was achieved by fermentation of shrimp biowaste. The carotenoid recovery in fermented shrimp biowaste was 70.6%. Thus, P. acidilactici was found to have a synergistic effect on fermentation of shrimp biowaste
