Diversity of Magnetotactic Bacteria in Sediment Sample from Yueyapao Respond to Seasons
The diversity of magnetotactic bacteria(MTB)in sediment sample from Yueyapao respond to seasonal dynamics were investigated.High-throughput sequencing was used to investigate the effects of different seasonal on MTB Alpha diversity,community composition,community function and the correlation between diversity and physicochemistry.The results showed that the abundance of MTB was high in summer and autumn,but low in spring and winter.Magnetospirillum was the only bacterial genus found in spring samples,Magnetospirillum was the dominant genus in autumn(73.42%)and winter(98.36%),and Magnetovibrio was the dominant community in summer(29.76%).RDA indicated that the distribution of most MTB were positively associated with Fe(Ⅱ),S and Sulfate.These findings would provide a theoretical basis to study of MTB in volcanic lakes response to seasonal dynamics.
