Cyclopentyl methyl ether (CPME) was evaluated for extracting oil or triacylglycerol (TAG) from wet cells of the oleaginous yeast Lipomyces starkeyi. CPME is a greener alternative to chloroform as a potential solvent for oil recovery. A monophasic system of CPME

Efficient bioethanol production from hemicellulose feedstocks by Saccharomyces cerevisiae requires xylose utilization. Whereas S. cerevisiae does not metabolize xylose, engineered strains that express xylose isomerase can metabolize xylose by converting it to xylulose. For this, the type II xylose isomerase

It is of great economic interest to produce succinate from low-grade carbon sources, e.g., lignocellulosic biomass hydrolysate, which mainly contains glucose and xylose. Inactivation of the glucose uptake system PtsG was evaluated for succinate production from xylose-rich feedstocks. Strains with

Four Gram-stain positive bacterial strains, designated as 4R1(T), 4R9, 4L13 and 4L18, isolated from seeds of hybrid maize (Zea mays L., Jingke 968), were investigated using a polyphasic taxonomic approach. The cells were found to be facultatively aerobic, motile, spore-forming
