“…Yeast concentration was determined by the dry weight method 14 . Ethanol content was determined by gas chromatography 15 and the fermentable sugars concentration was estimated using the 3,5-dinitrosalicylic acid method 16 . The half effective concentration (EC50) was calculated by the least square regression method based on the CFU number at different…”

Ionic liquid (IL) pretreatment of lignocellulosic materials has provided a new technical tool to improve lignocellulosic ethanol production. To evaluate the infl uence of the residual IL in the fermentable sugars from enzymatic hydrolysis of IL pretreatment of lignocellulosic materials on the subsequent ethanol fermentation, the toxicity of the IL 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) to Saccharomyces cerevisiae AY93161 was investigated. Firstly, the morphological structure, budding and metabolic activity of Saccharomyces cerevisiae AY93161 at different Cl inhibited the growth and ethanol production of Saccharomyces cerevisiae AY93161. This toxicity study provides useful basic data for further development in lignocellulosic ethanol production by using IL technology and it also enriches the IL toxicity data.

“…This consequently results in an increase in surface area, a decrease in the degree of polymerisation and crystallinity of cellulose and the depolymerisation of lignin which ultimately improves the substrates' accessibility to enzymatic attack [115,116]. Microwave based pre-treatments have been performed in aqueous environments, often in combination with water [117], organic solvents [118], alkali [119][120][121] and dilute-acid based solutions [122]. Furthermore, such pre-treatments have been shown to work effectively with a range of different lignocellulosic feedstocks, such as rape straw [122], sugarcane bagasse [123,124], wheat straw [125,126], sago [127] and Brewer's Spent Grains (BSG) [128,129].…”

Bioenergy, derived from biomass and/or biological (or biomass-derived) waste residues, has been acknowledged as a sustainable and clean burning source of renewable energy with the potential to reduce our reliance on fossil fuels (such as oil and natural gas). However, many bioenergy processes require some form of pre-treatment and/or upgrading procedure for biomass to generate a modified residue with more suitable properties and render it more compatible with the specific energy conversion route chosen. Many of these pre-treatments (or upgrading procedures) involve some form of substantive heating of the biomass to achieve this modification. Microwave (MW) heating has attracted much attention in recent years due to the advantages associated with dielectric heating effects. These advantages include rapid and efficient heating in a controlled environment, increasing processing rates and substantially shortening reaction times by up to 80%. However, despite this interest, the growth of industrial MW heating applications for bioenergy production has been hindered by a lack of understanding of the fundamentals of the MW heating mechanism when applied to biomass and waste residues. This article presents a review of the current scientific literature associated with the application of microwave heating for both the pre-treatment and upgrading of various biomass feedstocks across different bioenergy conversion pathways including thermal and biochemical processes. The fundamentals behind microwave heating will be explained, as well as discussion of the imperative areas which require further research and development to bridge the gap between fundamental science in the laboratory and the successful application of this technology at a commercial scale.

Kod uzorka tretiranog mikrotalasima, veća je potrošnja glukoze tokom SSF procesa u odnosu na kontrolni uzorak, a nakon 48 h postignuta je niţa koncentracija glukoze u odnosu na kontrolni uzorak i iznosila je 0,67 g/l (što odgovara potrošnji glukoze tokom SSF procesa od 99,54%).…”
