the study of single cell protein production possibility by yeasts (saccharomyces cerevisiae and saccharomyces carlsbergensis) from stick water of kilka fish meel factories in mazandaran

abstract these days, scientsts search for cheap protein sources because of growthing of population.one of these sources is single cell protein.this study deals with single cell protein production process by saccharomyces cerevisiae and saccharomyces carlsbergensis .these yeast are known as the most ideal and practical eukaryotic microorganism in biological studies. in this survey we added the waste of kilka fish meal factories (stick water) in mazandaran and analyzed physical and chemical factors in the lab.the yeast medium was ygb (yest extract glucose broth). it is used control medium and medium whitch has 50% and 100% stick water in order to investigation of growthing yeast. producted organizem are analyzed for dry material percent,moisture,protein,ash and amino acid profile. in order to analyze of results, we used spss and anova system. in this survey, the mount of single cell protein production in saccharomyces carlsbergensis was more than saccharomyces cerevisiae. but we dident watch any obviously different between them.
