| Summary: | Optimization of the process conditions of mixed culture of bacidiomycete fungi for 11 improved protein enrichment of fruit peels is necessary to ease replication and 12
scale-up processes. Six-day fermentation period and temperature of 32°C were 13 optimum for elevated protein synthesis and enzyme activities (78.99 units/ml for 14
α-amylase and 0.36 units/ml for cellulase). A highly significant quadratic model 15 obtained from Face Centered Central Composite Design (FCCCD) described the 16 process optimization. Linear effect of pH and inoculum size were significant (p < 17 0.05) while pH and moisture content (MC) interact significantly. 70.2% MC, pH 18
5.4 and 6.1% inoculum were the optimum level for a maximum crude protein 19 synthesis of 198.77 mg/g. The crude protein contained essential and non-20
essential amino acid at a comparable level with other bioprocessed materials that 21 are currently used as animal feed supplement. |
