Changes in fatty acid composition in Pseudomonas putida and Pseudomonas stutzeri during naphthalene degradation.
The effects of naphthalene on the whole cell-derived fatty acid composition of Pseudomonas putida and Pseudomonas stutzeri during naphthalene degradation were investigated. These strains differed in their abilities to degrade naphthalene and in 1,2-catechol dioxygenase activities. The cells of both strains reacted to the addition of naphthalene with an increase in the saturated/unsaturated ratio. The dynamic changes comprised also alterations in the percentage of hydroxy, cyclopropane and branched fatty acids. Upon the exposure of naphthalene, new fatty acids were detected.
