Abstract

Fatty acid composition during naphthalene utilization was investigated in three strains of bacteria Pseudomonas vesicularis, Pseudomonas stutzeri and Pseudomonas sp. JS150 that expressed different naphthalene degradation abilities. All strains significantly changed their cellular fatty acid profiles as a response to naphthalene exposure. Since naphthalene was present in the medium P. stutzeri increased ratio of saturated/unsaturated fatty acids from 1.1 to 2.1 and Pseudomonas sp. JS150 from 7.5 to 12.0, respectively. In contrast, this ratio decreased from 2.1 to 1.1 in P. vesicularis under the same growth conditions. The changes comprised also alterations in the percentage of selected groups of fatty acids: iso and anteiso, hydroxy and cyclopropane fatty acids. Our results showed that naphthalene induced in tested strains different changes in fatty acids composition. It may suggest that in the presence of naphthalene microorganisms used different adaptive mechanisms to maintain the cells in appropriate physiological state.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
