Effect Of Dosage Rhizopusoligosporus, Aspergillusoryzae, Trichodermaviride, And Trichodermareesei On Viability, Reducing Sugars, And Nutritional Value Of Corn Cobss Fermentation

A research toward the effect of single culture of Rhizopusol igosporus, Aspergillusoryzae, Trichodermaviride, and Trichodermareesei with various dosages of inoculums and incubation periode toward viability, sugar content of reductant and improvement of nutrition quality of corncob has been done. The purpose of the research was to find out about the extent of viability of the fungi on corncob substrate, and the capability in decomposing the substrate to improve the nutrition quality. The descriptive method was used for nutrition quality analysis (crude protein, crude fiber and crude fat), the complete randomized block design was used for the measured of fungi growth (the amount of fungi (TPC), pH, temperature and water content), and the sugar content of reductant for 8 days of fermentation process. The research result showed that the fermentation process was carried satisfactorily, while the reductant sugar content produced was also increasing. The analysis result on nutrition content showed that 6 days fermentation was the optimum time for fungi growth. Trichodermaviride with dosage 3% and incubation periode in 6 days is the best fungi that can growth in corncobs. The highest rate of reductant sugar produced by Trichodermaviride with dosage 3% and incubation periode in 6 days. The fungus that would increase the nutrition content of corncob was Rhizopusoligosporus with dosage 3% and incubation periode in 6 days the highest crude protein 8.95%, the lowest crude fiber 19.49% and crude fat 1.85%.
