“…The studies were triggered by the fact that this agricultural by-product possesses a moderate amount of nutrients, is locally available, and is relatively cheap. However, its quality is poor due to the presence of high fiber, particularly cellulose and mannan, imbalanced amino acids, and contamination of nutshell [2]. Attempts to overcome these problems have been done either biologically, physically, or enzymatically.…”

A study was conducted to determine the effect of fermented palm kernel meal (FPKM) with different levels of ammonium sulfate (AS) plus enzymatic hydrolyzation on the nutritive value and digestibility of the diets. The PKM was added with 0, 3, and 6% AS and then fermented with Saccharomyces cerevisiae for 5 days. The FPKM was hydrolyzed with a multi-enzyme product (FHPKM) and then included in the diets. The diets were: T-1 (PKM), T-2 (FPKM), T-3 (FHPKM), T-4 (FPKM with 3% AS addition), T-5 (FHPKM with 3% AS addition), T-6 (FPKM 6% AS addition), T-7 (FHPKM with 6% AS addition). The diets were fed to 140 laying hens for 30 days. The study used a completely randomized design with 7 treatments and 5 replications. Data were analyzed with the variance analysis. The results showed that fermentation increased the protein content of PKM and decreased the crude fiber content. The AS addition increased protein content linearly. Enzymatic hydrolyzation of FPKM increased significantly protein and crude fiber digestibilities (P<0.05). The addition of 6% AS increased the apparent metabolizable energy of the diets significantly (P<0.05). In conclusion, Fermentation increased the quality of PKM, and enzymatic hydrolyzation of FPKM increased protein and crude fiber digestibilities.

“…Decomposition of these polysaccharides, mainly comprising cellulose and hemicellulose, in an in vivo enzymatic manner has been shown to be beneficial for the growth performance of livestock and poultry . Feeds derived from certain kinds of plants, such as palm kernel cake and copra meal, are rich in cellulose and mannan . Adding cellulase and mannanase into these feed stuffs will facilitate the release of their nutritional components in the gastrointestinal tract.…”

Cellulase and mannanase are both important enzyme additives in animal feeds. Expressing the two enzymes simultaneously within one microbial host could potentially lead to cost reductions in the feeding of animals. For this purpose, we codon-optimized the Aspergillus niger Man5A gene to the codon-usage bias of Trichoderma reesei. By comparing the free energies and the local structures of the nucleotide sequences, one optimized sequence was finally selected and transformed into the T. reesei pyridine-auxotrophic strain TU-6. The codon-optimized gene was expressed to a higher level than the original one. Further expressing the codon-optimized gene in a mutated T. reesei strain through fed-batch cultivation resulted in coproduction of cellulase and mannanase up to 1376 U·mL and 1204 U·mL, respectively.

The low quality of palm kernel meal (PKM) is due to the presence of high fibrous fraction. Fermentation of a low-quality feedstuff by using fungi could improve its quality. An experiment was done to determine the effect of fungi fermented palm kernel meal on the performance of broilers. Palm kernel meal was fermented by different fungi (Aspergillus niger, Trichoderma viride and Pleorotus ostreatus). The study used 200-day-old chicks and the chicks were randomly placed in brooder cages. The broilers were fed with starter and grower diets from days 1 to 21 and days 21 to 42 respectively. Feed and water were provided ad-libitum. The treatments diets were R1: basal diet (0% PKM), R2: (10% PKM), R3: 10% Aspergillus niger fermented PKM, R4: 10% Pleorotus ostreatus fermented PKM, R5: 10% Trichoderma viride fermented PKM, R6: 20% PKM, R7: 20% Aspergillus niger fermented PKM, R8: 20% Pleorotus ostreatus fermented PKM, R9: 20% Trichoderma viride fermented PKM. A completely randomized design was used in this study. Data were analyzed by the analysis of variance. The inclusion of 20% PKM in the diet decreased body weight gain and feed intake. Supplementation of the diets with 20% fungi fermented PKM could maintain body weight gain to the same level of those birds fed the basal diets. The percentage of gizzard weight was higher in birds fed the basal diet than the other treatment birds. In conclusion, fermentation of PKM with Aspergillus niger, Trichoderma viride and Pleorotus ostreatus could improve its quality. The performance of broilers fed the 20% PKM could be maintained provided.
