Spathaspora passalidarum是近来发现的一种能天然利用木糖产乙醇的酵母菌,其发酵木糖速度比葡萄糖快,而且能混合发酵木糖,葡萄糖和纤维二糖.主要从氮源种类及浓度,接种量,转速及装液量,初始pH值等方面对Spathaspora passalidarum突变株U-30木糖乙醇发酵进行了研究,得到的优化摇瓶培养基组成为:初始木糖浓度为100 g/...
Cost-effective production of biofuels from lignocellulose requires the fermentation of d-xylose. Many yeast species within and closely related to the genera Spathaspora and Scheffersomyces (both of the order Serinales) natively assimilate and ferment xyl

This chapter studies the genus Spathaspora. In the determination of the asexual reproduction it is seen that yeast cells are mostly globose and form by multilateral budding. Septate hyphae and pseudohyphae are present. In sexual reproduction it is found that the allantoid asci arise without ...
Spathaspora passalidarum is a xylose-fermenting microorganism promising for the fermentation of lignocellulosic hydrolysates. This yeast is more sensitive to ethanol than Saccharomyces cerevisiae for unclear reasons. An RNA-seq experiment was performed to identify transcriptional changes in S. passalidarum...

Spathaspora passalidarumThe yeast Spathaspora passalidarum is able to produce ethanol from D-xylose and D-glucose. However, it is not clear how xylose metabolism is affected by D-glucose when both sugars are available in the culture medium. The aims of this work were to evaluate the ...
