“…Milling quality can be compared by the evaluation of fractional composition of milled biomass. Research evidence suggests that plant mass should be milled into particles smaller than 2-3 mm, 5 mm and bigger particles should make up not more than 5% and dust (smaller than 0.3 mm particles) should make up not more than 10-15% (Cheng, Timilsina, 2011;Yousuf, 2012). Our study showed too high content of dust (38.4%) in the feedstock from Germany, in Lithuanian samples dust content did not exceed the requirements and was below 15%.…”

“…Different biofuels are generated from diverse renewable resources and biodiesel is one of the most important transport fuels that can be obtained from biomass using different conversion processes (Demirbas, 2009;Cheng, Timilsina, 2011). Gasification of lignocellulosic biomass provides a way to produced different liquid fuels (Simmons, 2012), therefore biodiesel can be produced from all types of biomass that can be gasified, herewith technologies for converting biomass to biodiesel also are at various stages of development (Yousuf, 2012). When developing technologies for biomass conversion, several important aspects such as biomass feedstock potential and quality should be considered.…”

When developing various technologies designed for biomass conversion into biofuels, it is important to establish the suitability of raw material of lignocellulotic, non-food plants such as Miscanthus, whose biomass has a good energy potential. Biomass productivity, quality and its suitability for processing under more northern climatic conditions are important factors to be considered. Experiments were aimed to estimate quality and technological parameters of Miscanthus growing, harvesting and processing into synthetic diesel, to evaluate chemical, physical and mechanical properties of biomass and to determine energy consumption necessary for biomass preparation for conversion into synthetic diesel. The study object was biomass of Miscanthus (Miscanthus × giganteus Greef et Deu) produced under Lithuanian and German climate conditions. Miscanthus harvested in the autumn produced up to 9.42 t ha -1 dry matter (DM) yield, which was significantly higher in the treatments fertilised with a higher nitrogen rate. The content of cellulose (413-456 g kg -1 DM) and hemicellulose (204-236 g kg -1 DM) was very similar at all fertilisation levels. The highest content of lignin (117 g kg -1 DM) was established in the treatments fertilised with 120 kg ha -1 N. The spring-harvested Miscanthus biomass had significantly lower moisture content and the yield was significantly lower, too. While preparing the biomass as feedstock for synthetic diesel the greatest reduction in moisture content (to 8.59 ± 1.38%) occurred when Miscanthus biomass was chopped, pre-dried and milled, and particles larger than 2 mm accounted for the largest share. The energy use for chopping of autumn-harvested biomass was lower and chopping efficiency was higher compared with the spring-harvested biomass. The composition of major components of synthetic fuel from Miscanthus biomass was very similar to that of mineral diesel.

Rhodococcus opacus produces intracellular lipids from the biodegradation of lignocellulosic biomass. These lipids can be used to produce biofuels that could potentially replace petroleum-derived chemicals. Current studies are focusing on deconstructing lignin through efficient and cost-effective pretreatment methods and improving microbial lipid titers. R. opacus can reach high levels of oleaginicity (>80%) when grown on glucose and other aromatic model compounds but intracellular lipid production is much lower on complex recalcitrant lignin substrates. This review will discuss recent advances in studying R. opacus lignin degradation by exploring different pretreatment methods, increasing lignin solubility, enriching for low molecular weight lignin compounds and laccase supplementation.

“…Lignocellulosic biomass is considered as a reliable renewable source for the production of biodiesel, bioethanol, biogas and bio-H 2 [1][2][3]. The conversion of lignocellulosic biomass to biofuels requires the following common steps: hydrolysis of cellulose and hemicellulose, sugar fermentation, lignin residue separation and finally recovery and purification of biofuels in order to fulfill fuel specifications .…”

Abstract. Biofuels production is mostly oriented with fermentation process, which requires fermentable sugar as nutrient for microbial growth. Lignocellulosic biomass (LCB) represents the most attractive, low-cost feedstock for biofuel production, it is now arousing great interest. The cellulose that is embedded in the lignin matrix has an insoluble, highlycrystalline structure, so it is difficult to hydrolyze into fermentable sugar or cell protein. On the other hand, microbial lipid has been studying as substitute of plant oils or animal fat to produce biodiesel. It is still a great challenge to extract maximum lipid from microbial cells (yeast, fungi, algae) investing minimum energy.Electroporation (EP) of LCB results a significant increase in cell conductivity and permeability caused due to the application of an external electric field. EP is required to alter the size and structure of the biomass, to reduce the cellulose crystallinity, and increase their porosity as well as chemical composition, so that the hydrolysis of the carbohydrate fraction to monomeric sugars can be achieved rapidly and with greater yields. Furthermore, EP has a great potential to disrupt the microbial cell walls within few seconds to bring out the intracellular materials (lipid) to the solution. Therefore, this study aims to describe the challenges and prospect of application of EP technique in biofuels processing.
