abstract
The research concentrates on utilization of remains of marine organisms accumulated on sea shore to be used as a culture medium for fermentation in purpose of obtaining biomass –rich in protein using strains of microorganisms Saccharomyces cerevisiea, Aspergillus niger and Geotrichum candidum comparatively protein content was evaluated before and after acidic hydrolysis fermentation optimum conditions of temperature and pH primary, concentration the remains and the duration of incubation were determined .Findings show that the protein was directly proportional to duration of incubation which would take days, in which protein content were (28.52, 25,13, 20.46%) of dry matter using Aspergillus niger, Saccharomyces cerevisiea and Geotrichum candidum, respectively, while protein content was 3.44% of dry matter of the initial sample, further more fodder mixture was applied to groups of poultry and protein source feed (soybean) in a commercial fodder was replaced with the resulted biomass and the daily gain Average was 18.70g and feed conversion was 2.05 for the studied chicks of ages ranged 3-16 days.
