  • Abstract:

Fermentation is one of the oldest applied biotechnological methods been employed in food processing for many years.
Oil palm wastes are acceptable to ruminant at low level inclusion in the diet. Solid state fermentation of oil palm wastes
was carried out for five days. Microbial analysis, chemical and proximate compositions of the wet and dry bioconverted
samples were determined. The bacterial population of oil wastes during fermentation decreased from 1.0 x 108 to 1.6 x
107cfu/ml. Isolated bacteria included Bacillus cereus, Bacillus subtilis, Micrococcus luteus, Proteus vulgaris, and
Staphylococcus aureus. Fungi load also increased from 1.0 x 103 to 2.0 x 104sfu/ml. The isolated fungi were Aspergillus
niger, Brachysporium nigrum, Neurospora crassa, and Saccharomyces cerevisiae. Titratable acidity, pH and
temperature of the oil palm wastes during fermentation were in the range of 0.03 - 0.77%, 4.16 - 4.60 and 29.50 –
32.650C respectively. There was great increase in the protein, fibre, ash and fat content. The study had shown that oil
palm wastes can be bioconverted to animal feeds and this would reduce environmental pollution.
