Abstract

We have earlier reported chemotaxis of a Gram-negative, motile Ralstonia sp. SJ98 towards p-nitrophenol (PNP), 4-nitrocatechol (NC), o-nitrobenzoate (ONB), p-nitrobenzoate (PNB), and 3-methyl-4-nitrophenol (MNP) that also served as sole source of carbon and energy to the strain [S.K. Samanta, B. Bhushan, A. Chauhan, R.K. Jain, Biochem. Biophy. Res. Commun. 269 (2000) 117; B. Bhushan, S.K. Samanta, A. Chauhan, A.K. Chakraborti, R.K. Jain, Biochem. Biophy. Res. Commun. 275 (2000) 129]. In this paper, we report chemotaxis of a Ralstonia sp. SJ98 toward seven different nitroaromatic compounds (NACs) by drop assay, swarm plate assay, and capillary assay. These NACs do not serve as sole carbon and energy source to strain SJ98 but are partially transformed in the presence of an alternate carbon source such as succinate. This is the first report showing chemotaxis of a bacterial strain toward co-metabolizable NACs.
