| Pseudomonas arsenicoxydans |
Description is based mostly on API 20 NE strips (bioMerieux).
Positive results for arginine dihydrolase, catalase, oxidase, tyrosine hydrolysis,and acid production from glucose.
Can utilize: D-arabitol, L-histidine, D-fructose, D-glucuronic acid, D-saccharic acid, Tween 40, L-pyroglutamic acid, L-arabinose,
citrate, malate, D-mannose, D-mannitol, N-acetyl-glucosamine, potassium gluconate, capric acid, acetate, and sorbitol.
Negative results for casein hydrolysis, aesculin hydrolysis, gelatin hydrolysis, H2S production, indole production, lecithinase, lysine
decarboxylase, nitrate reduction, ornithine decarboxylase, PNPG, Tween 80 hydrolysis, and tryptophan deaminase.
No utilization of myo-inositol, D-aspartic acid, L-rhamnose, D-glucose-6-phosphate, p‐hydroxyphenylacetic acid, sucrose, trehalose,
adipate, D-maltose, phenylacetate, butyrate, ethanol, propionate, tartrate and aesculin.
Variable results for urease and glucose utilization.

forming.
Colonies are of about 1 mm in diameter on LB agar. Growth occurs at 4-37 ºC
(optimally at 30 ºC), at pH 6.5 and 10.0 (optimal 7.5-8.0) and in the presence of 0-2%
(w/v) NaCl (optimal growth occurs in 0% NaCl media). No growth at 41 ºC and pH 6.0
or 10.5. Fluorescent pigments are not produced on King B medium. Aerobic.

Isolated from sediment samples from the Camarones Valley in the Atacama Desert, Chile.
Strain is able to tolerate 5 mM As[III] and to oxidize 100% of the arsenite present in the medium with lactate as a carbon source.
