Abstract

Highlights: Food and kitchen waste suitable for production of value added products. Mixed consortium produced 5.123 g/L of PHB. Waste to wealth strategy adopting biorefinery approach. Abstract: The present investigation gives an insight on the potential of food and kitchen waste as a suitable feed stock for the production of biopolymer, biofuels, enzymes and chemicals. Media engineering improved poly-3-hydroxybutyrate (PHB) production from 0.91 g/L to 5.132 g/L. There is a five-fold increase in PHB production. The food and kitchen waste was also evaluated for the production of bioethanol, 2, 3 – butanediol, and pectinase. Saccharomyces cerevisiae produced 0.316 g of bioethanol, Bacillus sonorensis MPTD1 produced 2.47 (µM/mL)/min of pectinase and Enterobacter cloacae SG1 produced 3 g/L of 2, 3-butanediol with a productivity of 0.03 g/L/h using food and kitchen waste as carbon source. Targeting on multiple value added products will improve the overall process economics.
