Biodiversity and composition of bacterial communities inhabiting the surface of altered tuff
Tuff is a kind of volcanic clastic rock rich in Al, Si and K elements, tuff weathering plays important roles in the process of soil formation, fertility maintenance and cycling of the geochemical elements. In this study, less and more altered tuff and the soil samples were collected from Fuzhou in Jiangxi. The bacterial communities and diversity of the altered tuff and soil samples were investigated by Illumina Miseq high-throughput sequencing technology. The correlation between bacterial communities and the geochemical factors was also analyzed. The carbon source utilization ability and mineral weathering ability of the bacteria were evaluated through the BIOLOG micro plate system and the cultured method. Furthermore, genomics and transcriptome were used to study the mechanisms involved in the bacterial adhesion influence on the mineral weathering.
