Catalog Number FM-2266
Product Name Marine Oxidation Fermentation Medium (MOF Medium)
Aspect Light yellow to pinkish purple powder
Application | Based on the oxidative and fermentative metabolism of carbohydrates, this product allows the differentiation of marine bacteria. |
Principle | Marine bacteria exhibit different reactions: carbohydrate-fermenting types turn both tubes (covered and uncovered) from red to yellow; carbohydrate-oxidizing types change only the uncovered tube. Non-oxidative, non-fermentative types do not change color and show an alkaline (red to deep pink) reaction in the uncovered medium. |
pH | 8.0±0.2 |
Colour and Clarity of Prepared Medium | Pink, clear to slightly milky gel |
Formulation (/L) |

Directions | Suspend 22.14 g in 1000 ml of purified/distilled water. Heat to boiling to completely dissolve the medium. Autoclave at 15 pounds pressure (121°C) for 15 minutes. Cool to 45-50°C and aseptically add sterile glucose solution (or other carbohydrate of choice) to a final concentration of 1%. Mix well and dispense into sterile test tubes. |
