Within the proteobacteria, betaproteobacteria were the dominant class in groundwater (40% of total), with a mix of beta- and alphaproteobacteria in the soil-water (Fig.
Taxonomic distribution of sequences from the sugarcane and banana groundwater samples within the Proteobacteria, Betaproteobacteria, and Burkholderiales.
On the basis of 16S rDNA sequence analysis, the isolated ARB were assigned to alphaproteobacteria (n = 4), betaproteobacteria (n = 1), and the Bacteroides-Cytophaga-Flexibacter group (n = 2).

Members of the following phyla were detected in nearly all of the samples: Actinobacteria, Bacteroidetes, Chloroflexi, Cyanobacteria, Firmicutes, and Proteobacteria (Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria, and Gammaproteobacteria).
