Aromatic acids are chemoattractants for Pseudomonas putida.
A quantitative capillary assay was used to show that aromatic acids, compounds that are chemorepellents for Escherichia coli and Salmonella sp., are chemoattractants for Pseudomonas putida PRS2000. The most effective attractants were benzoate; p-hydroxybenzoate; the methylbenzoates; m-, p-, and o-toluate; salicylate; DL-mandelate; beta-phenylpyruvate; and benzoylformate. The chemotactic respons...
متن کاملTaxis of Pseudomonas putida F1 toward phenylacetic acid is mediated by the energy taxis receptor Aer2.
The phenylacetic acid (PAA) degradation pathway is a widely distributed funneling pathway for the catabolism of aromatic compounds, including the environmental pollutants styrene and ethylbenzene. However, bacterial chemotaxis to PAA has not been studied. The chemotactic strain Pseudomonas putida F1 has the ability to utilize PAA as a sole carbon and energy source. We identified a putative PAA ...
متن کاملChemical effectors cause different motile behavior and deposition of bacteria in porous media.
We tested the hypothesis whether chemically induced motility patterns of bacteria may affect their transport in porous media. Naphthalene-degrading Pseudomonas putida G7 cells were exposed to glucose, salicylate, and silver nanoparticles (AgNPs) and their motility was assessed by computer-assisted, quantitative swimming and capillary-based taxis determinations. Exposure to salicylate induced sm...
متن کاملA methyl-accepting protein is involved in benzoate taxis in Pseudomonas putida.
Pseudomonas putida is attracted to at least two groups of aromatic acids: a benzoate group and a benzoylformate group. Members of the benzoate group of chemoattractants stimulated the methylation of a P. putida polypeptide with an apparent molecular weight of 60,000 in sodium dodecyl sulfate-polyacrylamide gels. This polypeptide is presumed to be a methyl-accepting chemotaxis protein for severa...
