A kind of preparation method of composite photosynthetic bacteria preparation

Abstract

The invention provides a preparation method of a compound photosynthetic bacterial preparation which can be stored for a long time and can quickly degrade harmful substances such as ammoniacal nitrogen and hydrogen sulphide in aquatic water. Seed activated culture, seed culture and illumination culture by virtue of an anaerobic fermentation tank are carried out on thiocapsa roseoppersicia in purple sulphur photosynthetic bacteria and rhodomicrobium vannielii in purple non-sulphur photosynthetic bacteria, so that a high-concentration compound photosynthetic bacterial preparation of the thiocapsa roseoppersicia and rhodomicrobium vannielii is obtained; and the compound photosynthetic bacterial preparation can quickly degrade the ammoniacal nitrogen and hydrogen sulphide in the aquatic water in aquatic and marine environments, so that the ammoniacal nitrogen and hydrogen sulphide in the aquatic water are reduced or eliminated, and yield and / or quality of aquatic and marine animals are / is improved.

Description

technical field [0001] The invention belongs to the technical scope of a functional microbial preparation, and in particular relates to a preparation method of a composite photosynthetic bacteria preparation that can quickly degrade ammonia nitrogen, hydrogen sulfide and other harmful substances in aquaculture water with long storage time. 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 and ammoniacal nitrogen in anaerobic zones and underlying sediment...

[0007] Moreover, from the existing literature, most of the composite photosynthetic bacteria only carry out mixed culture of bacteria in the family Rhodospiraceae, and there is no report on the mixed culture of bacteria in the family Rhodospiraceae and Chromobacteriaceae.

[0008] In addition, general photosynthetic bacteria are vegetative cells, which are not easy to store. Generally, the longest storage time at room temperature is 3-6 months. If the storage time is exceeded, the survival rate is very low. This is also a big disadvantage of photosynthetic bacteria in aquatic applications.
