Ethanol production from Rice (Oryza sativa) straw by simultaneous saccharification and cofermentation.

Comparison of saccharification and fermentation of steam exploded rice straw and rice husk

BACKGROUND Rice cultivation produces two waste streams, straw and husk, which could be exploited more effectively. Chemical pretreatment studies using rice residues have largely focussed on straw exploitation alone, and often at low substrate concentrations. Moreover, it is currently not known how rice husk, the more recalcitrant residue, responds to steam explosion without the addition of chem...

Downstream optimization of fungal-based simultaneous saccharification and fermentation relevant to lignocellulosic ethanol production

To support the inefficient limitation of long-term biosystem by well-known simultaneous saccharification and fermentation (SSF), electron beam irradiated rice straw (at 80 kGy, 1 MeV, and 0.12 mA) was fermented using fungal-based simultaneous saccharification and fermentation (FBSSF) by saprophytic zygomycetes Mucor indicus. Based on the growth optimization (by response surface methodology), th...

The optimized CO2-added ammonia explosion pretreatment for bioethanol production from rice straw

A CO2-added ammonia explosion pretreatment was performed for bioethanol production from rice straw. The pretreatment conditions, such as ammonia concentration, CO2 loading level, residence time, and temperature were optimized using response surface methodology. The response for optimization was defined as the glucose conversion rate. The optimized pretreatment conditions resulting in maximal gl...

Impact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice

Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
