摘要

摘要本研究报道了新型产氢微藻十字花菜Carteria crucifera AARL G045与其菌群共培养具有较高的光自养产氢潜力。比较了固定化和游离细胞在光自养和光发酵条件下的产氢量。从十字花菜Carteria AARL G045培养物中分离出两个菌群，经16S rDNA序列分析鉴定为农杆菌G045-01和光阳航空微生物G045-02。结果表明，十字花菜Carteria crucifera AARL G045与a . kwangyangensis G045-02共培养产生的氢气量比单藻培养高约1.32倍。此外，微藻和细菌的游离细胞共培养产生的氢比在海藻酸钙中共固定产生的氢多约2.04倍。

Photoautotrophic Production of Hydrogen in Carteria Crucifera AARL G045 Co-Cultured with Bacterial Flora

Abstract This study reports on high potential of photoautotrophic biohydrogen production in co-culture of the novel hydrogen producing microalga Carteria crucifera AARL G045 with its bacterial flora. Hydrogen production from immobilised and free cells were compared under photoautotrophic and photofermentation conditions. Two bacterial floras of Carteria crucifera AARL G045 cultures were isolated and identified by 16S rDNA sequence analysis as Agrobacterium tumefaciens G045-01 and Aeromicrobium kwangyangensis G045-02. As a result, co-culture of Carteria crucifera AARL G045 and A. kwangyangensis G045-02 generated higher level of hydrogen gas than that of the mono algal culture by about 1.32 times. In addition, co-culture of both free cells of the microalga and the bacterium produced higher hydrogen than both co-immobilisation in calcium alginate by about 2.04 times.
