Swamp Rhodopseudomonas of using nitrite nitrogen in high effect, and application

Abstract

This invention relates to a kind of photosynthetic bacterium that has a high assimilation utility to nitrite nitrogen. More specifically, this invention provides a Rhodopseudomonas palustris strain that can assimilate nitrite nitrogen, and its r ejuvenation, preservation, biological detection and application. The photosynthetic bacterium is a kind of biological water purifier and biological fertilizer, and can be used in controlling the content of nitrite nitrogen in water body for aquaculture, improve environmental pollution, and eliminate cinnamic acid and benzoic acid. The photosynthetic bacterium can be used as nitrogen-fixing biological fertilizer and cucumber growth promoter.

Description

technical field

[0001] The invention relates to a method capable of efficiently utilizing nitrite nitrogen (in the form of NO 2 - Nitrogen-containing compounds that exist in the form of salts and salts) photosynthetic bacteria, specifically providing a Rhodopseudomonas palustris 2-8 strain (CCTCC) that can efficiently assimilate and reduce nitrite nitrogen M 205147) and its industrialized cultivation method, strain preservation method, strain rejuvenation method and bioassay method for nitrite nitrogen elimination. It belongs to the category of biological water purifiers and biological fertilizers. Background technique

[0002] Residual bait, fish and shrimp excrement, dead biological residues, drugs, and fertilizers in aquaculture water accumulate, decompose, and transform at the bottom of the water body, forming hydrogen sulfide, ammonia nitrogen, nitrite nitrogen, and other nitrogen oxides that are harmful to fish. Shrimp has toxic compounds that deteriorate water qual...
