Few studies have examined the bacterial communities associated with photosynthetic sacoglossan sea slugs. In this study, we determined the bacterial diversity in the clarki ecotype, Elysia crispata using 16S rRNA sequencing. Computational analysis using QIIME2 revealed variability between individual samples, with the Spirochaetes and Bacteroidetes phyla dominating most samples. Tenericutes and Proteobacteria were also found, among other phyla. Computational metabolic profiling of the bacteria revealed a variety of metabolic pathways involving carbohydrate metabolism, lipid metabolism, nucleotide metabolism, and amino acid metabolism. Although associated bacteria may be involved in mutually beneficial metabolic pathways, there was a high degree of variation in the bacterial community of individual slugs. This suggests that many of these relationships are likely opportunistic rather than obligate and that many of these bacteria may live commensally providing no major benefit to the slugs.

光合sacoglossan,Elysia crispata的clarki生态型中的细菌多样性。

很少有研究检查与光合作用参海参有关的细菌群落。在这项研究中,我们确定了克拉克生态型Elysia crispata中的细菌多样性使用16S rRNA测序。使用QIIME2进行的计算分析揭示了各个样品之间的变异性,其中螺旋藻和门生细菌占多数。除其他门外,还发现了Tenericutes和Proteobacteria。细菌的计算代谢谱分析揭示了多种代谢途径,涉及碳水化合物代谢,脂质代谢,核苷酸代谢和氨基酸代谢。尽管相关细菌可能参与了互惠互利的代谢途径,但个体鼻涕虫的细菌群落高度不同。这表明这些关系中的许多可能是机会性的,而不是专心的,而且这些细菌中的许多可能会成比例地生活,而对sl却没有太大的好处。
