摘要：

This paper appraises the potential of marine crustacean shell waste from the world's fishing industry for bioconversion to industrial products and envisages almost total low-waste utilisation of such materials. Techniques for the processing of waste shells are considered and compared. We additionally investigate what is considered a vital early stage in shell processing - the viability of a lactic acid fermentation on demineralised shell for deproteinisation under both aerobic and anaerobic conditions. An integrated bioconversion scheme is proposed whereby protein, pigment (astaxanthin) and the main biopolymer constituent, chitin, can be isolated for industrial or commercial use. The scheme also suggests further conversion of the chitin to its monomer, N-acetylglucosamine, for use as a sugar or as a medium source for production of microbial biomass protein.
