Morphology | Methylovorus glucosotrophus |
CELLULAR |
Staining | Gram negative |
Morphology | rods (0.5-0.6 x 1.0-1.4 um) are straight or slightly curved and occur singly or in paris |
Motility | |
Specialized structures | slime may be produced but no capsules, endospores, intracellular membranes, sheaths or prosthecae are detected |
Division | binary fission |
COLONIAL |
Solid surface | On methanol mineral salt agar colonies are circular, 1-2 mm in diameter, with an entire edge, convex, and translucent to opaque, pink, creamy or milky in colour. Pyocyanin and fluorescein are not produced |
Liquid | no aggregation of pigmentation observed |
Growth Parameters | Methylovorus glucosotrophus |
PHYSIOLOGICAL |
Tropism | chemoorganotroph |
Oxygen | aerobe respiratory metabolism |
pH | optimum pH 7.0-7.2 |
Temperature | optimum 35- 37 oC |
Requirements | Methanol and glucose are used as energy sources. Some strains grow slowly on methylated amines, inulin and betaine. Nitrates, amonium salts, methylated amines glutamate and eptones serce as nitrogen sources |
Products | acetoin, indole, H2S and NH3 are not produced milk not hydrolysed. Acid nu no gases from glucose. Fatty acid composition is primarily of the nonhydroxylated straight chain saturated and monosaturated types with C16:0 and C16:1-7 |
Enzymes | urease positive, catalase positive, oxidase positive. peroxidase variable, arginine dihydrolase negative |
Unique features | assimilate methanol carbon thorugh the RuMP pathway and ammonia via the glutamate cycle |
