Chemical and biological characterization of siderophore produced by the marine-derived Aureobasidium pullulans HN6.2 and its antibacterial activity

Abstract

After analysis using HPLC and electronic ion spray mass spectroscopy, the purified siderophore produced by the marine-derived Aureobasidium pullulans HN6.2 was found to be fusigen. The purified desferric fusigen still had strong inhibition of growth of the pathogenic Vibrio anguillarum while the fusigen chelated by Fe3+ lost the ability to inhibit the growth of the pathogenic bacterium. The added iron in the medium repressed expression of the hydroxylase gene encoding ornithine N5-oxygenase that catalyzes the N5-hydroxylation of ornithine for the first step of siderophore biosynthesis in the yeast cells while expression of the hydroxylase gene in the yeast cells grown in the medium plus ornithine was enhanced.

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.
