| Summary: | The factors that influenced the protein content of the biomass produced after the solid
state fermentation were studied. Two types of raw materials (palm kernel cake and
seaweed) which were already proven to contain various types of nutritional
compounds, had been used as substrates for supporting the growth of two compatible
microorganisms, Phanerochaete chrysosporium and Candida utilis that were used in the
fermentation process. The effect of fermentation parameters (initial pH, moisture
content and inoculum size) on the amount of bioprotein produced after the
fermentation was determined. Maximum bioprotein content found in the final product
of fermentation process was 247.1 mg/g with the optimum parameters obtained were
3.5, 71.0% and 8.0% for initial pH, moisture content and inoculum size respectively. The
other factors that influenced the fermentation process such as time and temperature of
incubation were also studied. Results showed that the temperature of 28°C and
incubation of six days gave the highest amount of bioprotein content in the final
product. The effects of the experimental fish feed towards the performance of fish were
also studied. |
