Fluid nutrient medium for promoting growth of halophilic nitrite oxidizing bacteria

A fluid nutrient medium for promoting the growth of halophilic nitrite oxidizing bacteria contains 0.3g to 0.7g of glucose, 0.6g to 1.4g of sodium nitrite, 0g to 0.04g of manganese sulfate monohydrate, 0.6g to 1.5g of potassium monohydrogen phosphate, 0.6g to 1.4g of sodium carbonate, 0g to 0.6g of potassium dihydrogen phosphate, 20g to 32g of sodium chloride, 2.8g to 3.6g of magnesium sulfate, 1.8g to 2.6g of magnesium chloride, 0.8g to 1.4g of calcium chloride, 0g to 0.6g of sodium bicarbonate, 0.3g to 1.1g of potassium chloride, 1ml to 10ml of vitamin solution, 1ml to 10ml of trace element solution and 60g to 80g of zeolite per 1000 milliliter of water, and the pH value is 8. The fluid nutrient medium is suitable for the growth of halophilic nitrite oxidizing bacteria, and can promote the growth and metabolism of halophilic nitrite oxidizing bacteria. The fluid nutrient medium provided by the invention can promote the growth of halophilic nitrite oxidizing bacteria in the fluid nutrient medium, so that the separation, purification, reproduction and denitrifying capability detection of halophilic nitrite oxidizing bacteria can become simple and feasible.
