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.

Pseudoalteromonas sp。的作用 MEBiC 03485关于十字形卟啉菌UTEX 161中生物量生产和硫酸化多糖生物合成的研究。

假单胞菌UTEX 161与假单胞菌属sp。考察了MEBiC 03485对克鲁维酵母的生长及其硫酸化多糖(EPS)的产生。MEBiC 03485菌株对十字花假单胞菌的生长,EPS的产生和EPS的质量具有有益的影响。这些作用归因于菌株MEBiC 03485分泌的化合物。值得注意的是,分泌化合物的处理还使细胞内藻红蛋白和藻蓝蛋白含量分别增加了89.4%和161%。另外,从MEBiC 03485处理中提取的EPS的生物活性倾向于比未经处理的对照更高。我们的结果表明,通过与共生菌株MEBiC 03485共培养,可以潜在地增强景天假单胞菌的生长及其EPS产量和质量的新方法。
