“…adhesin or floculin. This protein could increase the hydrophobicity of the cell surface that triggers hydrophobic interactions between cells and abiotic surfaces (Lavoie et al, 2011). Table 3 shows that the concentration of free and immobilized cell on untreated whole cell biocatalyst (WCB) are better and significantly different (P<0.05) than pretreated ones after 18-21 h fermentation.…”

Pretreated of sugarcane bagasse was used as a carrier for immobilization of Saccharomyces cerevisiae. Pretreatments were carried out by steaming, pressurized steam, and combination both of procedure. The objectives of this research was to investigate the effect of pretreatment on sugarcane bagasse to cells adsorption and bioethanol production. Immobilization process was conducted in a ratio of 2.5 g carrier/50 mL cell suspension. Whole cell biocatalyst as much as 1% (w/v) was used as inoculum for bioethanol fermentation. The best pretreated sugarcane bagasse for carrier of immobilized cells was obtained using steam treatment for 30 minutes. Those treatment improved the physical properties of carrier and increased the cell retention up to 10.05 mg/g. The use of whole cell biocatalyst after steaming pretreatment also enhanced ethanol yield 1.5 times higher than control.

“…Genetic engineering and synthetic biology have modified plant composition, to reduce conversion process cost or to develop and produce perennial feedstock with desired traits, reaching very quickly high energy capacities by spending lesser fertilizers and water (Simmons et al, 2008). Alternative biomass resources, such as lignocellulosic biomass, from either forestry or agriculture, are prerequisite to lower water and energy consumption without competing with food supplies (Lavoie et al, 2011). Nonfood feedstock, including high developing plantation trees like Populus and Eucalyptus which are broadly representative for the Northern or Southern Hemisphere, which produce large amounts of woody biomass (>50 m 3 ha -1 yr -1 ), offer advantages for energetic, environmental and economic criteria and renewable sources of lignocellulose feedstock (Hill et al, 2006;Mizrachi et al, 2012).…”

Since early human history and existence energy rich plants, wood and forest cellulosic material have been used for fire, light, heating, cooking and other daily activities. Fossil energy was the foundation of our modern society and industrialization since last two centuries, while exploration and exploitation of oil reserves and petrochemistry have largely shaped 20th century. Increasing concerns on environmental pollution, accelerated global warming, and global climate changes, continuing world's crude oil (fossil fuels) consumption and depletion, as well as energy security and energy crisis caused by daily burning large amounts of fossil fuels, led to the attraction, search and development of renewable, carbon-neutral, economically viable alternative energy sources, such as biofuels, slowly displacing petroleum fuels. In continuously growing human population reaching about 10 billion in 2050, various renewable energy sources are promoted and developed, to ensure rising energy demands in a world running out of fossil energy sources. Biofuels are produced from any kind of available biomass and categorized based on utilized carbon resources into first-, second- and third-generation. Nevertheless, biofuels’ future outlook is though beset by uncertainty. Hereby, various issues and concerns related to fossils and renewable biofuels are described and analyzed in present review article.

“…Such process could lead, depending on the operating condition, to the isolation of either hemicellulose or lignin in two steps or in a single step. Our team has demonstrated the feasibility of both processes for different substrates [12][13][14].…”

“…In second-generation ethanol, the source of carbohydrate considered is usually cellulose, which, in turns, is obtained from lignocellulosic biomass. Recent work by Lavoieet al [2] have depicted an overview of many types of lignocellulosic biomass and in most cases, cellulose, although a major component, is not the only one and is accompanied by lignin, hemicelluloses, extractives and, in case of agricultural biomass, proteins. High grade biomass (as wood chips, sugar cane or even corn) are usually very expensive (more than 100 USD/tonne) because, in most part, of the important demand related to those feedstock in industries and this is why cellulosic ethanol is more than often related to residual biomass.…”

“…Hemicelluloses account for 15-35 % of lignocellulosic biomass dry weight [2] and they are usually composed of different carbohydrates as well as small organic acids as acetic and formic acid. Glucose and xylose are often the most abundant sugars in hemicelluloses hydrolysis although mannose, arabinose and galactose might also be present in lower concentrations.…”
