The production of single cell protein from copra meal residue by saccharomyces cerevisiae and bacillus subtilis for development as animal feedstuff

Abstract

This experiment was conducted to study on single cell protein production from copra meal residue by Saccharomyces cerevisiae and Bacillus subtilis as animal feedstuffs. The experimental design was 4x3 factorial in CRD experiment with two factors were design to experiment. The first factor was comprised of fermented period (0, 15, 30 and 45 days). While, the second factor B was comprised of microorganism type (Saccharomyces cerevisiae, Bacillus subtilis and Saccharomyces cerevisiae combined with Bacillus subtilis). The results showed that interaction between factor A and B on pH (4.00-4.53) and percentage yield (29.21-33.80) were highly significantly different (P<0.01). However, Incubation temperature were not related between factor A and B. Additional, both factor have no effect to incubation temperature (P?0.05). For nutrients composition, the group was fermented Saccharomyces cerevisiae combined with Bacillus subtilis showed higher Crude Protein than other treatments (P<0.01). Optimum of period at days 45 showed that crude protein 14.77 percent was significantly (P<0.01) and pepsin digestibility 66.60 percent was significantly (p<0.01)
