Photosynthetic bacterium culture medium and preparation method thereof

Abstract

The invention provides a photosynthetic bacterium culture medium and a preparation method thereof, each liter of the culture medium comprises the following components: 0.05 g of potassium dihydrogen phosphate, 1.0 g of table salt or crude salt, 0.1 g of monosodium glutamate, 0.02 g of vitamin B complex and 50 ml of alcohol, yellow serofluid is supplemented to 1 L, the pH is adjusted to 6.8-7.6, and the yellow serofluid is hydrolyzed yellow serofluid. The photosynthetic bacteria culture medium contains proper carbon sources, nitrogen sources, trace elements and growth factors, is comprehensive in nutrition, can ensure normal growth requirements of photosynthetic bacteria, is simple in components and preparation method, is easy to obtain and cheap in raw materials, is stable in source, and is suitable for large-scale production. The culture medium is suitable for large-scale commercial activation and propagation culture of various common photosynthetic bacteria strains such as rhodopseudomonas palustris, rhodopseudomonas capsulatus and rhodospirillum rubrum.

Description

technical field [0001] The invention relates to a 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 an energy source and can perform photosynthesis under anaerobic light or aerobic dark conditions. It is found in soil, quagmire swamps, seawater, fresh water, sludge, plant roots, etc. It plays an important role in water purification, water quality monitoring, feed additives, bacterial fertilizers, etc. Based on the application advantages of photosynthetic bacteria, it is often necessary to carry out large-scale commercial culture and expansion. However, the current media for photosynthetic bacteria generally have shortcomings such as long enrichment time, many types of media components, and high cost. This greatly limits the application of photosynthetic bacteria in production. S...
