A meta-taxonomic analysis of anterior gut microbiota of Cirrhinus mrigala under test condition (Replicate 1)

The goal of this research is to learn how the fish gut microbiota changes in response to DO2 stress and how this shift in microbial population may reduce the population of obligately aerobic bacteria while increasing the population of facultative and obligate anaerobes. To define and compare the intestinal microbiota of C. mrigala, meta-taxonomic data analyses were performed using sequences of the V3 region of bacterial 16S rRNA genes amplified from DNA extracted from the fish gut.

本研究旨在探究鱼类肠道微生物群（gut microbiota）对DO2胁迫的响应变化规律，以及该微生物群落的演替如何降低专性需氧菌的种群丰度，同时提升兼性厌氧菌与专性厌氧菌的种群数量。为明确并对比印度鲮（C. mrigala）的肠道微生物群组成，研究人员以从鱼类肠道提取的DNA扩增得到的细菌16S rRNA基因V3区序列为数据来源，开展了宏分类学数据分析。
