The presence of furfural in the hydrolysates obtained from lignocellulosic biomass sources represents an enormous challenge during their fermentation because furfural is a toxic compound for different microorganisms. -1588 can grow and accumulate lipids using wood hydrolysate as a substrate containing up to 1 g/L of furfural. In this study, the capacity of -1588 to grow and accumulate lipids using furfural without glucose in the media has been observed. 1588 degraded up to 3 g/L of furfural into furfuryl alcohol (1.8 g/L) and 2-furoic acid (0.9 g/L). Furthermore, -1588 accumulated 52% and 30% of its dry weight into lipids using YM media and YM media without glucose, respectively. Fatty acids such as palmitic, stearic and oleic were the most abundant. Finally, -1588 could potentially utilize furfural as a carbon source.

微生物生长和脂质积累过程中糠醛的降解及其对红冬孢酵母 1588 的影响

从木质纤维素生物质来源获得的水解产物中存在糠醛，这在发酵过程中是一个巨大的挑战，因为糠醛对于不同的微生物来说是一种有毒化合物。 -1588 可以使用木材水解产物作为含有高达 1 g/L 糠醛的底物来生长和积累脂质。在这项研究中，观察了-1588 在培养基中使用糠醛而无需葡萄糖的情况下生长和积累脂质的能力。 1588 将高达 3 g/L 的糠醛降解为糠醇 (1.8 g/L) 和 2-糠酸 (0.9 g/L)。此外，使用YM培养基和不含葡萄糖的YM培养基，-1588分别将其干重的52%和30%积累成脂质。脂肪酸如棕榈酸、硬脂酸和油酸是最丰富的。最后，-1588 可能会利用糠醛作为碳源。
