Environmentally sustainable energy sources are called for due to contemporaneous development in industries along with the rapid pace of urbanization. Ethanol produced from biomass can be deliberated as a clean and safest liquid fuel and an alternative to fossil fuels as they have provided unique environmental, strategic economic benefits. For the past decade, it has been noticed that there is an increasing trend found in bio ethanol production which has created a stimulus to go for advancement in bio ethanol production technologies. Several feed stocks have been used for the bio ethanol production but the second generation bio ethanol has concentrated on the lignocellulosic biomass. Plenteous lignocellulosic biomass in the world can be tapped for ethanol production, but it will require significant advances in the ethanol production process from lignocellulosic because of some technical and economic hurdles found in commercial scale. This review will encompass the current status of bio ethanol production in terms of their economic and environmental viability along with some research gaps as well as policy implications for the same.

Ethanol production from lignocellulosic biomass is of economic interest due to the pressure to reduce fossil fuels consumption and land use for non-edible crops. Xylose is one of the main sugars obtained by hydrolysis of hemicellulose fraction of biomass, but industrial yeasts cannot ferment it. This work aimed to select, characterize and identify xylose-fermenting yeasts from Brazilian microorganisms collections with potential use in ethanol production. Xylose assimilation was tested by replica plating, and fermentation was tested with Durham tubes. Xylose-fermenting strains had their fermentative capacity quantified and compared to a reference strain (Scheffersomyces stipitis UFMG-IMH 43.2) and were identified by molecular techniques. Three strains isolated from plant exudates were able to ferment xylose and showed fermentative parameters similar to the reference strain. Two strains were identified as Candida parapsilosis and one was identified as Meyerozyma guilliermondii. The findings show the potential biotechnological use of these microorganisms.

Simultaneous Saccharification

Separate hydrolysis and fermentation (SHF) is the common process in producing ethanol from lignocellulosic biomass. Nowadays, simultaneous saccharification and fermentation (SSF) process has been seen as potential process for producing ethanol with shortens process time with higher yield of ethanol. Hence, in the current work, the utilization of empty fruit bunches (EFB) in SSF process was studied. In order to improve saccharification reactivity of EFB, hydrothermal pretreatment at 180 and 220 °C was used to pretreat EFB. The findings showed that SSF has the potential in producing ethanol from EFB.
