Process for biodiesel production from Cryptococcus curvatus

Co-utilization of glucose, xylose and cellobiose by the oleaginous yeast Cryptococcus curvatus

“…Gong et al [9] demonstrated that Lipomyces starkeyi simultaneously utilized cellobiose and xylose at their mass ratios of 2:1 and 1:1, while Hu et al [2] found that Trichosporon cutaneum could consume glucose and xylose in a simultaneous pattern at their mass ratios of 1:2 and 1:1. Among the well-studied oleaginous yeasts, Cryptococcus curvatus has also emerged as an ideal lipid-producing cell factory because its lipid content can reach up to 83 wt.% of dry cell weight with great performance for the utilization of a variety of substrates [10,11]. Our previous work revealed that C. curvatus was able to accumulate microbial lipids by using the hydrolysate from dilute acid pretreatment of wheat straw [12].…”

Single Cell Oil Producing Yeasts Lipomyces starkeyi and Rhodosporidium toruloides: Selection of Extraction Strategies and Biodiesel Property Prediction

“…Lipid extractions with hexane alone or combined with ethanol or isopropyl alcohol are preferable in most of the process development for biodiesel production from yeast oil [29][30][31][32][33][34].…”

Genome sequence of a microbial lipid producing fungus Cryptococcus albidus NT2002

“…Recently, the demands for renewable energy resources and sustainable transportation fuels have drawn great attention on account of the issues of depleted fossil fuel supplies, global warming, and imbalanced price (Beopoulos et al, 2011;Fei et al, 2011a;Ryu et al, 2013;Thiru et al, 2011). Biodiesel is an alternative energy form derived from renewabe bimass.…”

“…However, the unacceptable high cost of the vegetable oil namely soy bean, palm, and rapeseed, which account for about 70-90% of the total production cost (Vicente et al, 2009;Xue et al, 2008) is the major bottleneck for its broader application. One of the alternative ways to produce biodiesel in a green and sustainable manner, without competing with food crops, is the cultivation of oleaginous microorganisms, such as yeast, fungi, bacteria, and microalgae (Ryu et al, 2013;Thiru et al, 2011;Xu et al, 2013). Previous research showed that these microbes have several advantages in comprison to those vagetable oil and animal fats, such as high production rate, limited land-use, easy scale-up, and negligible effect of climate changes (Thiru et al, 2011).…”

Cryptococcus albidus, which is reported to use various carbon sources for cell growth and be albe to accumulate high amounts of lipid (up to 65% of dry cell weight) (Fei et al, 2011b), have been intensive research on high cell density cultivation and improving * Corresponding author at: College of Biotechnology and Pharmaceutical Engineering, Nanjing TECH University, Nanjing 211816, China.…”
