Microbial Diversity and Community Composition of Diverse Aquatic Ecosystems in Bangladesh: Insights from 16S and 18S Metagenomic Analyses

Aquatic ecosystems significantly influence global biodiversity and ecological processes. To unravel the mysteries of microbial communities within these ecosystems, we conducted a comprehensive metagenomic analysis across diverse aquatic habitats in Bangladesh. Our meticulous collection and processing of water samples, coupled with amplicon sequencing targeting the 16S and 18S rRNA genes and rigorous bioinformatics scrutiny provided deep insights into microbial diversity, intricately detailing the taxonomic distribution, community structure, and potential functional roles within the dynamic microbial assemblages. The 18S sequencing data highlighted the dominant eukaryotic group was Stramenopiles in both canal and lake habitats, while Nucletmycea and Chloroplastida were the dominating groups in the pond and marine environment respectively.

水生生态系统对全球生物多样性与生态过程具有显著影响。为揭示此类生态系统内微生物群落的奥秘，我们针对孟加拉国多样的水生生境开展了全面的宏基因组分析。我们通过严谨的水样采集与处理流程，结合针对16S与18S核糖体RNA（rRNA）基因的扩增子测序技术，辅以严格的生物信息学分析，深入解析了微生物多样性，并细致刻画了动态微生物群落的分类分布、群落结构及潜在功能角色。18S测序数据显示，运河与湖泊生境中的优势真核类群为不等鞭毛类（Stramenopiles）；而池塘与海洋环境中的优势类群则分别为核粘菌类（Nucletmycea）与叶绿体植物界（Chloroplastida）。
