The anaerobic fermentation experiments were carried out on a self-manufactured bench scale anaerobic digester with pig dung as feed material. Under mesophilic digestion condition, effects of different solid concentration of feed on characteristics of biogas production were investigated. Results...

Kenaf (Hibiscus cannabinus) has received considerable attention as a renewable resource because of its fast growth and low lignin content. In the present study, a combination pretreatment of kenaf core using electron beam irradiation (EBI) and dilute alkali was investigated to improve the sugar...

This study deals with the development of an eco-friendly hydrothermal pretreatment of wheat straw. This pretreatment involves moderate temperatures without generation of liquid fractions allowing to reduce the energy input consumption and the environmental impact and enhance the enzymatic...

Different response between woody core and bark of goat willow biomass to concentrated phosphoric acid pretreatment prior to enzymatic saccharification was investigated as changes of chemical compositions, carbohydrate compositions, and crystallinity of cellulose before and after pretreatment....

Рассмотрены различные виды гидролиза белкового сырья. Разработана технология производства мясного хлеба с добавлением коллагенового гидролизата. Показано,...

This study carried out an exergetic analysis of a proposed ethanol production scheme in which a new process – enzymatic hydrolysis of sugarcane bagasse – is integrated into the conventional process. Seven cases were evaluated, among them a conventional ethanol production plant without...

Cellulosic ethanol made from cellulosic biomass is a promising alternative to petroleum-based transportation fuels. Enzymatic hydrolysis is a crucial step in cellulosic ethanol production. In order to better understand the mechanisms of enzymatic hydrolysis, relationships between cellulosic...

Two different sugar yield definitions (cellulose-based and biomass-based) were used in reported studies investigating the relationship between biomass particle size and enzymatic hydrolysis sugar yield. It is noticed that these reported relationships are not consistent if sugar yield is defined...

The use of several lignocellulosic materials for ethanol fuel production has been studied exhaustively in the U.S.A.. Strong environmental legislation has been driving efforts by enterprises, state agencies, and universities to make ethanol from biomass economically viable. Production costs for...

Cryptococcus curvatus has great potential in fermenting unconditioned hydrolysates of sweet sorghum bagasse. With hydrolysates obtained by enzymatic hydrolysis of the solid pretreated by microwave with lime, the maximal yeast cell dry weight and lipid content were 10.83 g/l and 73.26%,...
