Abstract

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.

Description

technical field [0001] The invention relates to a simple and easy-to-manufacture photosynthetic bacteria culture medium and a preparation method thereof, belonging to the field of biotechnology. Background technique [0002] Photosynthetic bacteria is a general term for a class of prokaryotic microorganisms that use light as energy and can perform photosynthesis under anaerobic light or aerobic dark conditions. It plays an important role in water purification, water quality monitoring, feed additives, bacterial fertilizer, etc. Based on the application advantages of photosynthetic bacteria, it is often necessary to carry out large-scale cultivation of them. However, the medium used for photosynthetic bacteria generally has shortcomings such as long enrichment time, many types of medium components, and high cost, which are extremely limited. The application of photosynthetic bacteria in production. Contents of the invention [0003] In view of the deficiencies in the prio...
