The invention discloses a simple and easy-to-prepare photosynthetic bacteria culture medium and a preparation method thereof. Each liter of the culture medium is prepared from the following componentsby weight: 1.0-2.0 g of nitrogen, phosphorus and potassium compound fertilizer, 4.0-8.0 g of table salt or crude salt, 0.3-0.5 g of monosodium glutamate, 0.1-0.5 g of brown sugar, 0.01-0.03 g of complex vitamins B, 75-100 ml of alcohol, and water added to be 1 L. The photosynthetic bacteria culture medium comprises suitable carbon sources, nitrogen sources, microelements and growth factors, has comprehensive nutrition, and can guarantee the normal growth demand of photosynthetic bacteria, and the components and the preparation method are simple, raw materials are easy to obtain and cheap, sources are stable, and the simple and easy-to-prepare photosynthetic bacteria culture medium is especially suitable for farmers to independently activate and expand cultivation of the photosynthetic bacteria.

Simple and easy-to-prepare photosynthetic bacterium culture medium and preparation method thereof

The invention discloses a photosynthetic bacteria culture simple and convenient propagation culture medium. Per liter of an aqueous solution comprises the following components by mass: 2.5-3.5 g of sodium propionate, 1.0-2.0 g of ammonium chloride, 2.5-3.5 g of peptone, 8-10 g of sodium chloride, 1.0-1.5 g of sodium bicarbonate. 0.4-0.6 g of potassium dihydrogen phosphate, 0.1-0.3 g of magnesium sulfate, 0.24-0.26 g of sodium hydroxide, 0.03-0.05 g of manganese sulfate, 0.002-0.005 g of ferrous sulfate, and 0.0006-0.001 g of sodium glutamate. The photosynthetic bacteria culture simple and convenient propagation culture medium and the preparation method thereof do not need yeast cream, is low in production cost, and low in equipment requirement. Used water is tap water or well water, production operation is simple and convenient, and capacity of resisting sundry fungus is strong. In addition, photosynthetic bacteria generated by using the photosynthetic bacteria culture medium are highin viable count, and not easy to decay.
