Photosynthetic bacterium medium formula

Abstract

The invention discloses a photosynthetic bacterium medium formula which comprises 1.0g of ammonia chloride, 0.5g of dipotassium hydrogen phosphate, 0.2g of magnesium chloride, 2g of sodium chloride, 0.1g of a yeast extract and 900mL of water. After all the components are uniformly dissolved, sterilization is performed for 20min, then filtered 5.0g sodium bicarbonate / 50mL water and 50mL filtered ethanol are aseptically added, and then filtered 0.1N phosphoric acid is used to regulate a pH value to be 7.0 to obtain the photosynthetic bacterium medium formula. A product produced by the photosynthetic bacterium medium formula is not layered up and down, is uniform in color and does not have the any wall adhesion phenomenon; and as for the product produced by the photosynthetic bacterium mediumformula, the color is deeper and bright without parti-colour.

Description

technical field [0001] The invention relates to the technical field of photosynthetic bacteria, in particular to a photosynthetic bacteria medium formula. Background technique [0002] Photosynthetic bacteria are prokaryotic organisms that first appeared on the earth, are ubiquitous in nature, and have primitive light energy synthesis systems. They are the general term for bacteria that perform photosynthesis without oxygen release under anaerobic conditions. Negative bacteria are a class of microorganisms that use light as energy and can use organic matter, sulfide, ammonia, etc. in nature as hydrogen donors and carbon sources for photosynthesis under anaerobic light or aerobic dark conditions; photosynthetic bacteria are widely Distributed in soil, paddy fields, swamps, lakes, rivers and seas in nature, mainly in anoxic areas where light can penetrate in aquatic environments. [0003] In the prior art, there are many photosynthetic bacteria on the market that are layered ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are many photosynthetic bacteria on the market that are layered up and down, the upper layer is lighter, the lower layer is thicker, the upper layer is light in color, the lower layer is dark in color, and the bottom layer may have a layer of black precipitation; and many on the market The products all have the phenomenon of sticking to the wall, that is, a layer of reddish-purple color layer is formed on the wall of the container, just like paint, which cannot be washed off or wiped off.
