All strains were rod-shape cells with  a swollen terminal  end<br />Gram  negative, motile, non-halophilic, non-alkalophilic  and non-acidophilic,  and capable of utilizin<br />benzoate aerobically and photo-anaerobically. Sequence analysis of part of 16S rRNA genes showed that DS<br />1 and Cas-13 were closely related to Rhodopseudomonas palustris Strain 7 with a similarity of 97%, wherea<br />DS-4 may not be closely related to the former two strains with a similarity of 78% based on the constructe<br />phylogenic  tree. Spectral analysis indicated that the three  bacteria  had  bacteriochlorophyl  a  and norma<br />spirilloxanthin series. <br />Growth in medium enriched with vitamin and supplemented with benzoate as their sole C-sources wa<br />better than in medium without vitamin. Benzoate degradation in medium with vitamin was accelerated. Th<br />ability  to grow on benzoate without added vitamins indicated  that  the bacteria were able to synthesize  the<br />own vitamins. <br />Key words: anoxygenic photosynthetic bacteria/ benzoate degradation/ 16S rRNA gene.}, number={17}, journal={BIOTROPIA}, author={SURYANTO, DWI and SUWANTO, ANTONIUS and MERYANDINI, ANJA}, year={2011}, month={Nov.} }
