Morphology | Marinobacter hydrocarbonoclasticus |
CELLULAR |
Staining | Gram negative |
Morphology | rod shaped (0.3-0.6 x 2.0-3.0 um) have numerous surface blebs when grown on eicosane in mineral medium |
Motility | motile by means of a single, unsheathed polar flagellun in media containing 0.2-1 M NaCl. Cells are unflagellated in media with different concentrations of NaCl. |

Growth Parameters | Marinobacter hydrocarbonoclasticus |
PHYSIOLOGICAL |
Tropism | chemoorganotroph |
Oxygen | strict aerobe with a respiratory metabolism but grow anaerobically with nitrate or on succinate, citrate or acetate but not on glucose |
pH | |
Temperature | range 10- 45oC, optimum 32 oC |
Requirements | Extremely halotolerant can can grow in NaCl conentrations ranging from 0.08-3.5 M. HAVE AN ABSOLUTE REQUIREMENT FOR THE SOIDUM ION |
Products | grow on acetate, butyrate, caproate, succinate, fumarate, adipate, DL-lactate, and citrate as the sole carbon source but not on carbohydrates and amino acids |
Enzymes | oxidase, cytochrome oxidase, catalase tweenase and lecithinase positive |
Unique features | Degrader a large variety of aliphatic or aromatic hydrocarbons and produce a nondialyzabvle bioemulsifier when grown on hydrocarbons |
