“…However, using 5-10% ethanol in the blend will have little or no impact on fuel economy [93][94][95][96][97][98][99][100][101][102][103][104] . Further increasing the ethanol by ~20% reduces fuel economy ~1-3% (refs 105-114).…”

Though improvements in processing and technology are important, the fluctuating price of inputs such as molasses, corn, sugar beet, sugarcane, sweet sorghum, starch, etc. and their seasonal availability play an important role in ethanol industry. As a matter of fact, the ethanol industry based on conventional resources has reached its saturation point. Technologies for ethanol production from lignocellulosics are being developed by scientists world over with the objective of exploiting the potential of a resource, which is otherwise considered a waste, to generate energy. The focus has been to produce ethanol in a cost-effective manner, besides aiming to find use of its by-products as food supplements for cattles, etc. Recent developments like adoption of technologies such as dry grind fractionation, which is now commercially viable, would reduce the cost of milling; wet milling being costintensive and dry milling requiring smaller plants.

“…In most of the fermentation processes S. Cerevisiae is used. S. Cerevisiae is an efficient bio-ethanol producer due to its high tolerance to ethanol, low optimum pH range and anaerobic conditions requirement (Martıń, Galbe, Wahlbom, Hahn-Hägerdal, & Jönsson, 2002). However, S. Cerevisae is not much suitable for ethanol production from xylose as it needs modified strains or need the pretreatment of xylose by bacterial enzymes (Gong, Chen, Flickinger, Chiang, & Tsao, 1981) …”

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.

“…Because bagasse and sugarcane stalk straw have a similar cellulose:lignin:hemicellulose composition, the latter fulfills the same energy-providing purpose (Zanin et al, 2000). Cellobiase and endoglucanase from different sources and different types of pre-treatment are used in the processing of sugarcane bagasse (Martín et al, 2002;Neureiter et al, 2002;Hernández-Salas et al, 2009). Sugarcane bagasse is also used to produce cellulose film (Ruzene et al, 2009) and as an additive material in the production of cement (Sousa, 2009).…”

ABSTRACT. In this study, we measured the genetic diversity within and among a set of 9 commercial sugarcane varieties used for alcohol and sugar production using 17 microsatellite DNA markers. The UGSM148 and UGSM59 primers were monomorphic for all 74 sugarcane samples. The estimated proportion of simple sequence repeated (SSR) polymorphic loci was 88.23%; 17 alleles were detected. The mean gene diversity of all SSR loci was 0.7279. The
