“…The fermentation is performed by various strains of yeast and bacteria (Cao et al, 2014;Cheng et al, 2007;Pasha et al, 2007;Walfridsson et al, 1996). The selection of strain for bioethanol production is made by considering their productivity, tolerance to ethanol, fermentation inhibitors and severe pH and temperature conditions (Cao et al, 2014).…”

Enormous amount of biomass is depositing each day in the environment. The agriculture countries can make use of such resources for various useful purposes. Bioethanol is one of the important commodities which can be produced by using biomass. Bioethanol can be considered as future fuel which has the potential to replace fossil fuels. The selection of raw material, pretreatment process, saccharification and proper selection of yeast and bacteria strains are considered as the key steps in bioethanol production from biomass. Bioethanol is in fact a cheap source of energy and can help in clean environment management. However in few cases consideration are needed to overcome the anomalies of using some specific biomass resources which can affect our food reserves. A brief survey of the various important aspects involved in bioethanol production is done in this review to grasp the basic concept of bioethanol production from biomass.

“…When Martin and colleagues studied fermentability of the three hydrolyzates with a xylose utilizing Saccharomyces cerevisiae with and without nutrient supplementation they found that the H 2 SO 4 impregnated bagasse fermented considerably poorer than the situations found in the other two categories of the bagasse. Cheng et al (2007) have reported the ethanologenic fermentation of sugarcane bagasse hemicellulose hydrolyzates, pretreated by over-liming as well as electrodialysis and supplemented with nutrient materials employing Pachysolen tannophilus DW 06. These workers found that compared with detoxification by over-liming, detoxification by electrodialysis decreased the loss of sugars and increased the acetic acid removal.…”

“…After celluloses, hemicelluloses are the next most abundant polysaccharides in lignocellulosic biomasses (30). Although considerable research has focused on converting biomass cellulose to ethanol (38,39), less has been done on bioconverting hemicellulose components (6,10).…”

Ethanol Production Efficiency of an Anaerobic Hemicellulolytic Thermophilic Bacterium, Strain NTOU1, Isolated from a Marine Shallow Hydrothermal Vent in Taiwan

et al. 2011

A new extremely thermophilic, anaerobic, gram-negative bacterium, strain NTOU1, was enriched and isolated from acidic marine hydrothermal fluids off Gueishandao island in Taiwan with 0.5% starch and 0.5% maltose as carbon sources. This strain was capable of growth utilizing various sugars found in lignocellulosic biomass as well as xylan and cellulose, and produced ethanol, lactate, acetate, and CO 2 as fermentation products. The results of a 16S rRNA gene sequence analysis (1,520 bp) revealed NTOU1 to belong to the genus Thermoanaerobacterium. When tested for the ability to grow and produce ethanol from xylose or rice straw hemicellulosic hydrolysate at 70°C, the strain showed the highest levels of ethanol production (1.65 mol ethanol mol xylose −1 ) in a medium containing 0.5% xylose plus 0.5% yeast extract. Maximum ethanol production from the rice straw hemicellulose was 0.509 g g −1 , equivalent to 98.8% theoretical conversion efficiency. Low concentrations of inhibitors (derived from dilute acid hydrolysis) in the rice straw hemicellulose hydrolysate did not affect the ethanol yield. Thus, Thermoanaerobacterium strain NTOU1 has the potential to be used for ethanol production from hemicellulose.
