BIOREMEDIATION OF SEA FOOD WASTE IN SOLID STATE FERMENTATION ALONG WITH PRODUCTION OF BIOACTIVE AGENTS

Abstract

Sea food processing generates large volumes of waste products such as skin, head, tails, shells, scales, backbones, etc. Pollution due to conventional methods of sea food waste disposal causes negative implications on environment, aquatic life, and human health. Moreover, these waste products can be used for the production of high-value products which are still untapped due to inappropriate management. Paenibacillus sp. AD, known to act on chitinolytic and proteinaceous waste was explored for its potential to degrade various types of sea food waste in solid state fermentation. Effective degradation of sea food waste, generated from variety of sources such as fish scales, crab shells, prawn shells and mixture of such wastes was observed. 30 to 40 percent degradation in terms of decrease in the mass was achieved. Along with the degradation, chitinolytic and proteolytic enzymes were produced which can have various biotechnological applications. Apart from this, value added products such as chitin oligosaccharides and peptides of various degree of polymerization were also produced which can be used for various therapeutic purposes. Results indicated that Paenibacillus sp. AD can be used for the development of a process for the infield degradation of sea food waste.
