Bioethanol production from rice straw residues
A rice straw - cellulose utilizing mold was isolated from rotted rice straw residues. The efficient rice straw degrading microorganism was identified as Trichoderma reesei. The results showed that different carbon sources in liquid culture such as rice straw, carboxymethyl cellulose, filter paper, sugar cane bagasse, cotton stalk and banana stalk induced T. reesei cellulase production whereas g...
متن کاملBioethanol production from rice straw by popping pretreatment
BACKGROUND Rice straw has considerable potential as a raw material for bioethanol production. Popping pretreatment of rice straw prior to downstream enzymatic hydrolysis and fermentation was found to increase cellulose to glucose conversion efficiency. The aim of this study was to investigate the influence of popping pretreatment and determine the optimal enzyme loading using a surface response...
متن کاملBioethanol Production from Steam Explosion Pretreated Straw
1.1 Motivation and environmental aspects The combustion of fossil fuels is responsible for 73% of carbon dioxide emissions into the atmosphere and therefore contributes significantly to global warming. Interest in the development of methods to reduce greenhouse gases has increased enormously. In order to control such emissions, many advanced technologies have been developed, which help in reduc...
متن کاملCombined production of bioethanol and biogas from wheat straw
Due to the problems with environment and green house gases more biofuels as bioethanol and biogas needs to be produced to reduce the problems. Wheat straw as raw material is a good choice for ethanol and biogas production since wheat is the most produced crop in Sweden and the whole Europe and it isn’t competitive to food. In this study three different options for pretreatment of wheat straw, c...
متن کاملEvaluation of biobutanol production from non-pretreated rice straw hydrolysate under non-sterile environmental conditions.
The study aims to investigate a cost-effective approach to convert non-pretreated rice straw hydrolysate into biobutanol. The influences of the initial cell concentration and incubation temperature on biobutanol production were evaluated under both sterile and non-sterile conditions. Results indicate that 100% glucose utilization could be achieved for initial cell concentrations greater than 21...
