However, high cellulose contents may cause difficulty for organic digestion and slow down the nutrient absorption for plants. This study aims to reach the microorganisms or their combination for biodegradating the cassava peel waste. The initial result shows that after 21 days the glucose concentration in all samples was the highest during experiment times. The reducing glucose produced in mg/mL by the selected bacteria was 9.32, higher than the selected fungie of 1.57 mg/mL. The percentage degradation of cassava peel weigh was the highest for fungi which was 52% of weigh, respectively. Meanwhile, bacteria only degradated about 31.6% after 4 weeks. However, the combination between bacteria and fungi provides the highest glucose concentration, 19.29 mg/mL and digests 62% of the mass cassava in experiment. This study suggests that biodegradation of agro-wastes in the environment to reduce biomass waste pollution is very promising.展开更多

The experimental digester and the pilot were powered as follows: Lw + U + C (liquid waste + urine + cow dung). To the results, the experimental digester mesophilic with a progressive elimination of COD. Also, the nitrogen concentrations in the experimental reactor had little removal with alkaline pH. As for the biogas product in this digester, a volume of 3.6 m<sup>3</sup> was obtained with a positive flammability test. The transition from the laboratory scale to the semi-industrial scale retains the results of purification and fuel biogas production of the experimental digester.展开更多
