Taking into consideration the essential contribution of farming, it is of rising importance to add knowledge regarding bacterial species occurrence in water samples from aquaculture zones from the point of view of both the organism and public health. In the present study, we investigated the bacterial community existing in water samples from six aquaculture areas in the Thermaikos gulf, northern Greece, that may provoke toxicity in aquatic organisms and humans and may indicate environmental pollution in mussel production as well as algal blooms. Bacterial species were identified molecularly by sequencing of a partial 16s rRNA segment and were analyzed phylogenetically for the confirmation of the bacterial taxonomy. The results obtained revealed the presence of four bacterial genera ( sp., sp., sp., and sp.). Members of the and genera have been isolated from highly polluted sites, bacteria have been identified in samples derived directly from plastic debris, and bacteria are in line with microcystin detection. In this context, the monitoring of the bacteria community in mussel aquaculture water samples from the Thermaikos gulf, the largest mussel cultivation area in Greece, represents an indicator of water pollution, microplastics presence, algal blooms, and toxin presence.
考虑到农业的重要贡献，从生物体和公共健康的角度来看，增加水产养殖区水样中细菌物种出现的知识变得越来越重要。在本研究中，我们调查了希腊北部 Thermaikos 湾六个水产养殖区水样中的细菌群落，这些细菌可能会对水生生物和人类产生毒性，并可能表明贻贝生产以及藻类大量繁殖中的环境污染。通过对部分 16s rRNA 片段的测序对细菌物种进行了分子鉴定，并进行了系统发育分析以确认细菌分类。结果表明存在四个细菌属（sp.，sp.，sp. 和 sp.）。属和属的成员已从高度污染的地点分离出来，细菌已从直接来自塑料碎片的样本中鉴定出来，细菌与微囊藻毒素的检测一致。在这种情况下，监测希腊最大贻贝养殖区 Thermaikos 湾贻贝养殖水样本中的细菌群落是水污染、微塑料存在、藻类大量繁殖和毒素存在的指标。
