Hydrogen cyanide, a secondary metabolite of Pseudomonas aeruginosa
Abstract
Seventy-four of 110 strains of Pseudomonas aeruginosa tested produced detectable amounts of HCN from growth in 2% peptone or nutrient agar. Of the 25 species of 12 bacterial and fungal genera tested, other than P. aeruginosa, only P. fluorescens and P. polycolor gave positive HCN tests. Cyanide is produced after cessation of active growth. Iron was stimulatory to cyanogenesis in concentrations above 1 μM, while copper, zinc, cobalt, and manganese at concentrations of 20 μM had no effect. Cyanogenesis is dependent on the temperature of incubation within ranges which allow complete growth. Inorganic phosphate in concentrations between 90 and 300 mM allows growth but inhibits HCN production. Growth of cells anaerobically, using nitrate as the electron acceptor, results in low cyanide yields, which can be partially reversed by subsequent aerobic incubation. These results indicate that HCN is a secondary metabolite of P. aeruginosa.

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.
