Isolation and Selection of Indigenous Cellulolytic Microorganisms for Production of Palm oil Empty Fruit Bunches Compost

Abstract

The selection of 21 isolate microorganisms from the natural and bamboo forestsby the size of clear zone bigger than 18 mm. were selected and the 3 fungal, 1 actinomycetes and 4 bacterial were found. The study under 60-70 % of moisture condition in laboratory by measuring the C/N ratio, the results showed that DE1 and DE10 isolates gave C/N ratio of 30.7 and 31.0, respectively. The condition at pH 7-8.5 was good for the growth of microorganisms and the microbial population were highest at the period of 35-49 days after incubation. The effect of mixed culture showed that Formula 3 have the most effectiveness of oil-palm bunches degradation at 60 days. In field study, the total nitrogen, potassium, electrical conductivity (EC) were evaluate. The results showed that Formula 6 and Formula 5was found to be higher in total nitrogen as 8.36% and 6.50%, total phosphorus as 0.86% and 0.71%, potassium as 1.34% and 1.20%, respectively. Moreover, Formula 6 showed the highest electrical conductivity (EC) as 5.36 μS/cm because of formula 6 showed highest total potassium.
