Multivariate profiling of soil bacterial communities provides information that will possibly contribute to the conservation
and rehabilitation of the environment. In the Sakaerat Environmental Research Station, Thailand, the land degradation gradient, represented
by a dry evergreen forest (DEF) and bare ground (BG) as a result of deforestation and subsequent land degradation was determined. Profiling
was done with the antibiotic resistance most probable number (MPN) method (method 1), the antibiotic disc diffusion method (method 2) and
the Biolog method. Compread to the DEF soil, the BG soil had significantly lower moisture content and pH values (at p=0.05), and total C
and bacterial MPN count (at p=0.10). Profiles of the soils obtained by the antibiotic and the Biolog methods were analyzed. The profiling
methods scored Wilk
