以木聚糖为原料，采用珠江纤维弧菌-微藻共培养模式，对4种微藻进行了促生长研究。培养12 d后，共培养的小球藻、蛋白核小球藻和莱茵衣藻的生物量浓度与葡萄糖上的混合营养生长相当，杜氏藻的生物量浓度是葡萄糖上的1.6倍。比较转录组分析表明，木糖和木聚糖水解产物被C.这些活性底物可能是促进微藻生长的主要原因。这个C.珠江-微藻共培养模式是一种利用半纤维素生产低成本微藻生物柴油的潜在方法。(C)2015爱思唯尔有限公司版权所有。
In this work, a Cellvibrio pealriver-microalga co-cultivation mode was used to promote the growths of four microalgae by using xylan as feedstock. After 12 days of cultivation, the biomass concentrations of Chlorella sacchrarophila, Chlorella pyrenoidosa and Chlamydomonas reinhardtii in co-cultivation were equal to those in mixotrophic growth on glucose, and the Dunaliella was about 1.6-fold higher than that on glucose. The comparative transcriptomes analysis demonstrated that the xylose and xylan hydrolysates were catalyzed to some active substrates by C. pealriver via some functional enzymes; these active substrates are possibly responsible for the promotion of microalgal growth. This C. pealriver-microalga cocultivation mode is a potential method to produce low-cost microalgal biodiesel by using hemicellulose as feedstock. (C) 2015 Elsevier Ltd. All rights reserved.
