The effect of co-cultivation of Porphyridium cruentum UTEX 161 with Pseudoalteromonas sp. MEBiC 03485 on P. cruentum growth and its sulfated polysaccharide (EPS) production were examined. The strain MEBiC 03485 had beneficial effects on P. cruentum growth, EPS production, and EPS quality. These effects were due to a compound secreted by the strain MEBiC 03485. Notably, secretory compound treatment also increased intracellular phycoerythrin and phycocyanin content by 89.4% and 161%, respectively. In addition, the biological activities of EPS extracted from MEBiC 03485 treatment tended to be higher than the control without treatment. Our results suggest a novel approach for potentially enhancing the growth of P. cruentum and its EPS production and quality by co-culturing with the symbiotic strain MEBiC 03485.
研究了共培养紫球藻（Porphyridium cruentum）UTEX 161 和假交替单胞菌（Pseudoalteromonas sp.）MEBiC 03485 对紫球藻生长及其硫酸多糖（EPS）生产的影响。菌株 MEBiC 03485 对紫球藻生长、EPS 生产和 EPS 质量有有益影响。这些影响归因于菌株 MEBiC 03485 分泌的一种化合物。值得注意的是，分泌化合物处理还分别使藻红蛋白和藻蓝蛋白的含量增加了 89.4%和 161%。此外，来自 MEBiC 03485 处理的 EPS 的生物学活性趋于高于未经处理的对照。我们的结果表明，通过与共生菌株 MEBiC 03485 共培养，可能是一种增强紫球藻生长及其 EPS 生产和质量的新方法。
