“…However, the presence of cell wall degrading enzyme complex did 266 contribute to the efficiency of enzymatic saccharification. The primary mechanism was 267 hydrolysis of the residual hemicellulose and increase in cellulase accessibility to the 268 cellulose (Fan et al, 1987). Cell wall degrading enzymes have been reported to act on 269 even untreated soybean hulls, resulting in more than 97% increase in sugar yield during 270 ethanol production process, which is another reason for optimizing the dosage.…”

“…Lignocellulose is the most abundant renewable biological resource 1,2 continually replenished by photosynthetic reduction of carbon dioxide by sunlight energy 3 Lignocelluloses constitute a major portion of agricultural wastes and forest wastes 4 . Thus they are the most promising feedstock for the production of energy, food and chemicals 4,5 and their utilization could allow self-sustainable processes and products.…”

“…The bioconversion of cellulosic materials at economic rate will lead to the development of large-scale processes benefi cial to mankind 6 . Such processes as suggested by 3,6 would help alleviate shortages of food and animal feeds, solve modern waste disposal problem and diminish man's dependence on fossil fuels by providing a convenient and renewable source of energy in the form of glucose. Formation of soluble sugars from cellulose in agricultural residues relies on the sequential/coordinated action of individual components such as -exoglucanase, -endoglucanase and -glucosidase in cellulase enzymes 7 .…”

Cellulolytic enzymes on lignocellulosic substrates in solid state fermentation by Aspergillus niger

2007

The production of cellulolytic enzymes by Aspergillus niger on lignocellulosic substrates groundnut fodder, wheat bran, rice bran and sawdust in solid state fermentation in a laboratory scale was compared. Czapek Dox liquid broth amended with cellulose (0.5%) was used to moisten lignocellulosic solid supports for cultivation of Aspergillus niger. The production of fi lter paperase, carboxymethyl cellulase and -glucosidase were monitored at daily intervals for 5 days. The peak production of the enzymes occurred within 3 days of incubation. Among solid supports used in the study, wheat bran was the best solid matrix followed by groundnut fodder in production of cellulolytic enzymes in solid state fermentation. Groundnut fodder supported signifi cant production of FPase (2.09 FPU/g), CMCase (1.36 U/g) and -glucosidase activity (0.0117 U/g) in solid state fermentation. Considerable secretion of protein (5.10 mg/g) on groundnut fodder at peak time interval 1st day of incubation was recorded.

“…Such type of agricultural shift can reduce the production of other grains causing scarcity of food. The marginal lands that are being targetted are often inhabited and used by rural farmers for various subsistence purposes [83][84][85][86][87][88][89][90][91][92] .…”

Viable Feedstock Options and Technological Challenges for Ethanol Production in India

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.
