Carbon source used for regulation and control of microbial community in culture pond water body and application

Abstract

The invention provides a carbon source used for regulation and control of microbial community in culture pond water body and an application, the carbon source comprises the following components by weight part: 60-100 parts of soluble starch, 5-20 parts of vegetable protein and 5-20 parts of micromolecule organic acidity sodium salt. The experiment proves that the compound carbon source is capable of reducing ammonia nitrogen concentration of the pond water body, increasing algae abundance and controlling the aeromonas quantity, accordingly, the carbon source has large application potential on regulation and control of microbial community in culture pond water body.

Description

technical field [0001] The invention belongs to the field of biotechnology in aquaculture, and in particular relates to the regulation and control of carbon sources by microbiological communities in aquaculture ponds. Background technique [0002] Microbial communities, including bacteria, algae, protozoa, etc., play a key role in the purification of water quality and the flow of material and energy in the pond ecosystem. Due to the fact that the water body of intensive aquaculture ponds is often rich in nitrogen and the ratio of carbon and nitrogen is out of balance, the microbiological community is often in a state of evolution, and its functional structure is unstable, which makes pathogenic microorganisms easy to become the dominant population, and eventually causes frequent occurrence of diseases. Therefore, how to regulate the microbiological communities in ponds in order to maintain population diversity, make beneficial organisms in a dominant position, stabilize func...
