title: Community composition of soil bacteria nearly a decade after a fire in a tropical rainforest in East Kalimantan, Indonesia.
abstract: Soil bacterial community compositions in burnt and unburnt areas in a tropical rainforest in East Kalimantan, Indonesia, were investigated 8 and 9 years after a fire by denaturing gradient gel electrophoresis analysis targeting the 16S rRNA gene. Three study sites were set in the forest area devoid of fire damage (control), and in the lightly damaged and heavily damaged forest areas. Succession of aboveground vegetation in the two damaged areas had clearly proceeded after the fire, but the vegetation types still differed from the unburnt area at the time of this study. Community composition of total soil bacteria was similar among the three areas, and so was that of actinobacteria. However, the composition of ammonia oxidizing bacteria clearly differed depending on the presence or absence of past fire damage. These results indicate that even nearly a decade after the forest fire, impacts of the fire remained on the community composition of ammonia oxidizing bacteria, but not apparently on those of dominant bacteria and actinobacteria.
