| Abstrak/Abstract |
The objective of this study was to investigate the diversity of bacteria in the rhizosphere of Acacia grow in the forest
and different ages of revegetated land and nonrhizospheric bacteria from active tin mining soil on Bangka
Island with a metagenomic approach and to investigate its relationship with physicochemical properties of the soil
and its metal content. 17 species/genera were found in the four fields, and Bradyrhizobium is the dominant
genus. Bacterial communities of the forest (more than 5 years in revegetated post-tin mining land containing C, N,
P, and Fe) are Paraburkholderia sp., Bacillus sp., Candidatus-Xiphinematobacter, and Bacterium
enrichment. The physicochemical properties of soil from less than 5 years of revegetated contain Cu, Cr, and Mo,
and the dominant species in this soil were Bulkhorderia sp., Bacillus lehensis, B. fordii, B. thermolactis, Chloroflexi
bacterium, and Thermonosporaceae bacterium. The physicochemical properties of soil from the mining were
dominated by Cd and Ni, and the dominant species in this soil were Sinomonas atrocyanea. |
