Summary of "Burkholderia bannensis sp. nov., an acidic pH-neutralizing bacterium isolated from torpedo grass (Panicum repens) that grows in highly acidic swamps in Thailand."
Two strains of acidic pH-neutralizing bacteria, E25(T) and E21, were isolated from torpedo grass (Panicum repens) that grows in highly acidic swamps (pH 2 - 4) in actual acid sulfate soil areas of Thailand. The strains were Gram-negative, aerobic, non-spore-forming, and rod-shaped bacteria, having a cellular width of 0.6 - 0.8 microm and a length of 1.6 - 2.1 microm. These strains showed good growth between pH 4.0 and 8.0 and between 17 and 37 degrees C. The organisms contained ubiquinone Q-8 as the predominant isoprenoid quinone and C(16 : 0), C(17 : 0) cyclo, and C(18 : 1 )omega7c as their major fatty acids. Their fatty acid profiles were similar to those reported for other Burkholderia species. The DNA G+C content of these strains was 65 mol%. On the basis of 16S rRNA gene sequence similarity, these strains were shown to belong to the genus Burkholderia. Although the calculated 16S rRNA gene sequence similarity values of E25(T) to E21, B. unamae, B. tropica, B. sacchari, B. nodosa, and B. mimosarum were 100 %, 98.7 %, 98.6 %, 97.6 %, 97.4%, and 97.3 %, respectively, E25(T) and E21 formed a group that was distinct in the phylogenetic tree; and the DNA-DNA relatedness values of E25(T) to E21, B. unamae, B. tropica, B. sacchari, B. nodosa, and B. mimosarum were 90 %, 42 %, 42 %, 42 %, 45 %, and 35 %, respectively. The results of physiological and biochemical tests including whole-cell protein pattern analysis allowed phenotypic differentiation of these strains from the previously published Burkholderia species. Therefore, strains E25(T) and E21 represent a new species, for which the name Burkholderia bannensis sp. nov. is proposed. The type strain is E25(T) (= NBRC 103871(T) = BCC 36998(T)).
