Mussel processing wastes as a fermentation substrate

摘要: The Galician Rias Baixas (NW Spain) are a series of estuarine systems affected by the upwelling (Fraga, 1981, 1991), whose primary productivity, reaching 260 g carbon/m2/year 1976), is among highest in world. intense semiculture mussels developed with regard to these conditions, now generates approximately 250 000 metric tons/year (almost half world’s production), two thirds which found single system (the Ria Arousa). Only part this production directed fresh consumption, more than 60% — tendency increase being frozen or canned, means various processes involving common first step steam treatment that releases 300–500 1 effluents per ton raw treated mollusc. Due complete lack insight, mussel processing wastes (MPW), rich organic matter, particularly glycogen, dumped coastal waters, where they constitute an eutrophication factor seriously affects very medium resource.
