Abstract

A bioprocess system for the pilot scale production of the PECM at 1 MT capacity was established in order realize the full potential of the PECM technology as shown by its promising results at laboratory scale. The process design and construction of the pilot pant facility was jumpstarted with the construction of partial building shell and embedded electrical roughing-ins in concrete column. Critical equipment necessary to carry out the production quota were either fabricated or purchased. Optimization if the process conditions for the production of PECM was done u sing Response Surface Methodology. Fractional factorial design as used to screen for factors that has significant influence on the protein enrichment of copra meal since the pilot plant facility is not yet fully functional, a 250 kg/batch PECM was done using existing facilities and equipment of the laboratory. Quality monitoring of the produced PECM showed an increase in crude protein content from 19-21% to 32-37% in dry weight basis while fiber was significantly reduced. Limiting amino acids in swine and poultry diets such as lysine, methionine+cysteine, threonine and tryptophan were improved by 89%. The PECM product showed higher degree of present in A. niger. In vitro dry matter digestibility studies showed that the bioprocessing of copra meal into PECM enhances its dry matter digestibility from 33.51% to 48.01%. The aflatoxin content of both raw copra meal and PECM falls within the tolerance limit of 20 ppb whereas Salmonella contamination was not detected in both samples. Acute toxicity testing in mice indicates that PECM is safe and non-toxic even at high levels. Process conditions for the production of PECM powder inoculants were also established. Statistical screening methods were done to establish a suitable carrier for the propagation of A. niger 3104 at high cell viability counts. The cost of producing PECM at 100kg capacity is projected to be PhP 19.77 based on the overall mass balance. Commercial testing and distribution of PECM products were conducted in collaboration with potential investors, private sectors and other small scale livestock raisers.
