Attractive Surface Bacterial Communities Structure of Black and White Section from Yunnan Karst Area Stone

In this study,all stone samples were collected from four sites in karst areas of southeastern Yunnan Province of China,including Stone Forest Scenic in Shilin County (SL) located in Kunming City,Qingshui HETANG (QS),Puzhehei Scenic (PZ) and Shede Village (SD)in Qiubei Countylocated in Wenshan Zhuang and Miao Autonomous Prefecture,in June,2016.In addition,the samples collected from the same rock with black and white sections were named S and B during the sequencing process.Then,iron and manganese oxides were detected as the main mineral composition difference between contrastable samples by Raman.Moreover,electrochemical characterization showed that all black samples had photoelectrochemical activity in response to visible light, and the photocurrent density was of 4 times than white samples.The bacterial community structure maybe influenced by solar-mineral system.
