Fragilaria radians contamination study

16S metabarcoding analysis of F. radians (=S. acus subsp. radians) strain A280 at 2017, 2020, and 2021. The aim of this analysis was to identify whether this culture ever was contaminated by bacteria, and establish identity of the contaminant (if any)本数据集为2017年、2020年及2021年针对F. radians（=S. acus subsp. radians）菌株A280开展的16S元条形码分析（16S metabarcoding）。本次分析旨在确定该培养物是否曾被细菌污染，并鉴定污染物的种类（若存在）。
