FIG. 2.
RSGP analysis of community DNAs from N soil and S soil from a contaminated soil pile. Soil aliquots (1 g) were incubated with MS medium in desiccators equilibrated with toluene-vpo mixtures containing 0, 0.1, 10, and 100% toluene, as indicated, for 2 weeks, after which community DNAs were extracted and used for RSGP analysis. The calculated fraction (fx) for each genome represented on the filters, uncorrected for cross-hybridization, is plotted against the standard number (Table 1). The results of two representative incubations are shown; a total of three, three, five, and two incubations were done for 0, 0.1, 10, and 100% toluene, respectively.
