Synechocystis MCCB 114 and 115 were segregated as putative probionts for shrimp larvae from a collection of 54 cyanobacterial cultures enriched from seawater. On feeding Penaeus monodon post-larvae with the cyanobacteria, the generic diversity of the intestinal bacterial flora could be enhanced with substantial reduction or total absence of Vibrio spp. A significant difference (p < 0.001) in the percent survival of batches of post-larvae fed on the cyanobacterial cultures was observed and, on repeated challenge with V. harveyi, the relative percent survival of those batches of larvae fed on Synechocystis MCCB 114 and 115 was significantly higher. The Synechocystis MCCB 114 and 115 cultures were found to contain high levels of protein (34 to 43%), in addition to carotenoids.
聚球藻MCCB 114和115是从54种从海水中富集的蓝藻培养物中分离出来的，被认为是虾幼体的潜在益生菌。用这些蓝藻喂养斑节对虾后期幼体时，肠道细菌菌群的种类多样性可以得到增强，同时弧菌属大量减少或完全不存在。观察到用蓝藻培养物喂养的后期幼体批次的存活率存在显著差异（p < 0.001），在用哈维氏弧菌反复攻击时，用聚球藻MCCB 114和115喂养的那些批次幼体的相对存活率显著更高。除了类胡萝卜素外，还发现聚球藻MCCB 114和115培养物含有高水平的蛋白质（34%至43%）。
