“…The red yeast Rhodosporidium toruloides is an oleaginous mesophilic species. Rhodosporidium are able to carry out a number of diverse biochemical reactions such as biodegradation of epoxides, biphenyls and oxiranes (Smit, 2004), biosynthesis of carotenoids (de Miguel et al, 1997) and other types of biotransformations, but a major biotechnological exploitation is associated to their ability to convert glycerol and lignocellulosic biowastes into lipids (Hu et al, 2009;Yu et al, 2011). Among the oily yeasts, two novel species of the anamorphic basidiomycetous genus Trichosporon have been recently identified (T. cacaoliposimilis and T. oleaginosus) (Gujjari et al, 2011), despite lipid accumulation has not yet explored in the perspective of biodiesel production.…”

“…The increased levels of these substances can be explained by the formation of degradation products during thermal treatment of lignocellulosic plants [34][35][36]. Low amounts of inhibitors are favourable for hydrolysis and fermentation [20,21].…”

Corn cobs are a promising lignocellulosic substrate for the production of biofuels like bioethanol via conventional yeast or biodiesel via oleaginous yeast. Pretreatment of the substrate is essential for further hydrolysis and fermentation steps. This study focused on the steam explosion method as pretreatment. Therefore, different steam explosion severities were evaluated. (untreated) to a maximum of 214.9 g·kg -1 dry matter (190 °C/30 min). Furthermore, the mass recovery was calculated. At harsher pretreatment conditions, a significant mass loss was observed, estimated by the ash content in the recovered dry matter. The lowest recovery rate was observed for SF = 4.13 (190 °C/30 min) with 68.39%. The produced inhibitors were evaluated.

“…The lignin barrier that protects cellulose could be removed efficiently through copre-treatment, which facilitated the access of the cellulases to cellulose. As the lignin content decreased after the fungal-assisted pre-treatment, the pore size in the substratum became enlarged, resulting in greater surface accessibility for the hemicellulase and cellulase (Bak et al 2009;Zhao et al 2009;Yu et al 2011). Figure 5 shows a total mass balance graph based on 100 g of dry biomass.…”

The potential of nine fungal strains for pre-treating Eucommia ulmoides Oliver seed shells (EUOSSs) was investigated. Phanerochaete chrysosporium Burds. was found to be the best fungal strain for pretreating EUOSSs. After co-pre-treatment with acetic acid and P. chrysosporium Burds., which was cultivated in a solid state with an approximately 74% moisture content at 28 °C for 28 d, the weight loss of the EUOSSs was 51.9%. Because of the cooperative efficiency of the biochemical pre-treatment, an enzymatic digestibility value of 86.6% was achieved. The high digestibility value was attributed to the synergism between the acetic acid and fungal treatments, which led to improved enzymatic accessibility of the EUOSSs. As an environmentally friendly processing method, fungal pre-treatment can save a great amount of energy and, in combination with an acetic acid treatment, is more efficient at improving the rate of sugar transformation.
