example 1

[0034] A method for preparing photosynthetic bacteria that improves the yield and / or quality of aquatic animals, adopting the species of Rhodospira exothhianospira in the photosynthetic bacteria is cultivated according to the following steps:

[0035] 2. Double-layer flat plate seed activation culture: Streak the strain of Exothorhodospiribacter sasuraui on the solid photosynthetic bacteria medium in the lower layer, then pour a layer of agar medium on it, and culture it under light at 30°C for 5 days, and wait for the streaking The colony turns red and grows a lawn, which can be the activated strain;

[0036] , Seed culture: Inoculate the activated strain into the seed liquid medium, the temperature is 30°C, the light intensity is: 3000lux, light anaerobic culture for 7 days, and the OD660 of the detected seeds is 1.8, which is the seed culture medium;

[0037] , Fermentation culture: Inoculate the seed culture liquid and the fermentation medium with an inoculum ratio o...

Abstract

The invention provides a preparation method of a photosynthetic bacterium capable of improving the yield and/or the quality of aquatic animals, and particularly provides a preparation method of a photosynthetic bacterium preparation good enough to control, minimize or eliminate hydrogen sulfide in water. The preparation method comprises the steps that ectothiorhodospira shaposhnikovii in a purple sulfur photosynthetic bacterium is subjected to seed activating culture, seed culture, and anaerobic fermentation pot illumination culture, and the high-concentration photosynthetic bacterium preparation is obtained. The photosynthetic bacterium preparation can efficiently degrade hydrogen sulfide in the water in aquatic and marine environments, so that hydrogen sulfide in the water is minimized or eliminated, and the yield and/or the quality of the aquatic and marine animals are/is improved.

Description

technical field [0001] The invention belongs to the technical scope of functional microbial preparations, and in particular relates to a preparation method of photosynthetic bacteria for improving the yield and / or quality of aquatic animals. Background technique [0002] Many aquatic and marine environments, such as fish farms, ponds, ponds, lakes, estuaries, and oceans contain one or more aerobic zones and one or more anaerobic zones in the water column. In the aerobic zone near the surface of the water column, air and wind introduce oxygen, while aerobic bacteria produce phosphate, carbon dioxide, and ammonia, among others. In the anaerobic zone near the bottom of the water column, anaerobic microorganisms tend to produce hydrogen sulfide, ammonia, and methane, among others. Accumulations of hydrogen sulfide in anaerobic zones and their underlying sediments are toxic and undesirable because they stress aquatic and marine fauna. In some cases, such as in commercial fish a...
