As the gradual up-growing trend of industrialization and urbanization leading steady increment of demand of energy; eco-friendly, bio degradable, cost competitive and promising source of energy with high sustainability is toughly needed for the new era of modern world. Hydrolysis of cellulose by cellulase enzymes is a vital candidate for this option. It is a solid-liquid heterogeneous reaction; strongly affected by the non-reaction resistances caused most notably by the crystalline structure; reaction environment parameters as temperature, pH, characteristics of enzyme, cell & substrate loading and hence must have to be defined for specific enzyme-substrate amalgamation. In this present investigation, glucose was produced from rice straw using cellulytic enzyme pseudomonas sp., isolated from municipal solid waste. Glucose yield was found to increase as the rice straw particle size decreased from 0.5 mm to 45 ?m, while the optimal temperature and pH were found within the range of 30°C and 7.0 respectively. The concentration and rate of glucose production was observed to depend on pretreatment of rice straw, substrate concentration and enzyme loading. A kinetic model rate expression has been developed for such a process based on the Michaelis – Mentens and Line weaver–Burk approach. Comparison between the experimental data and those predicted from the rate model indicate good agreement with a mean absolute deviation of about 0.304916.

This study aimed to find out the optimum pH range and a buffer feeding method for butyric acid production from rice straw by undefined mixed culture. A serial experiment was conducted at various pH levels from 5.0 to 7.0. The results showed that neutral pH improved rice straw conversion and hence carboxylic acid production. The highest butyric acid production was achieved at pH range of 6.0 to 6.5. Another serial experiment was performed at pH 6.0 to 6.5 buffered with CaCO3, NaHCO3, NH4HCO3 and their combinations, respectively. The results indicated that different buffers had different effects on product spectrum, and that CaCO3 combined with NaHCO3 was an effective buffer for butyric acid production. This study presents an alternative way for butyric acid production from lignocellulosic biomass without supplementary cellulolytic enzyme.

And a straw fermentation of rice (Oryza sativa) against production. Research glucose levels was done using a completely randomized design (CRD) with factorial pattern 4 variation of the concentration of Trichoderma sp. (0%, 24%, 36% and 48%) and fermentation time (3, 4, 5and6 weeks), glucose levels were analyzed using DNS with UV-Visible spectrophotometry. The measurement results showed that the highest glucose levels obtained at various concentration Trichoderma sp. 36% fermentation time during the five week sthat is equal to 14.525%. There is a positive interaction between the concentration of Trichoderma sp. and the fermentation time, the best combination of time and fungal concentration of 5 weeks and 36%, respectively.Keywords : Rice straw, Trichoderma sp., Fermentation, DNS, Spectrophotometer Uv-Visibel, Glucose.

Rice straw (RS) is an abundant, readily available agricultural waste, which shows promise as a potential feedstock for Asian ethanol production. To enhance release of glucose by enzymatic hydrolysis, RS was pretreated with aqueous ammonia (27% w/w) at two pretreatment temperatures: room temperature and 60°C. Statistical analysis indicated similarity of enzymatic glucose production at both pretreatment temperatures after 3-day incubation. Chemical composition, FTIR, and EDX analyses confirmed the retention of glucan and xylan in the pretreated solid, but significant reduction of lignin (60.7% removal) and silica. SEM analysis showed the disorganized surfaces and porosity of the pretreated RS fibers, thus improving cellulose accessibility for cellulase. The crystallinity index increased from 40.5 to 52.3%, indicating the higher exposure of cellulose. With 10% (w/v) solid loadings of pretreated RS, simultaneous saccharification and fermentation yielded a final ethanol concentration of 24.6 g/L, corresponding to 98% of maximum theoretical yield. Taken together, aqueous ammonia pretreatment is an effective method to generate highly digestible pretreated RS for bioethanol production and demonstrates potential application in biorefinery industry.
