Kocuria palustris strain and applications thereof

Abstract

The invention relates to a Kocuria palustris strain and applications thereof. The strain is Kocuria palustris FSDN-A, and is preserved in the China General Microbiological Culture Collection Center on July 14, 2011, wherein a preservation number is CGMCCNO.5061. According to the present invention, the strain can adopt nitrite nitrogen or nitrate nitrogen as a substrate to complete a denitrification process; when the Kocuria palustris FSDN-A is adopted to treat ammonia-containing wastewater, characteristics of simple process, high denitrogenation activity, and high concentration organic carbon source tolerance are provided; after the strain is poured, the system is rapidly started; and the strain has broad application prospects in wastewater denitrogenation treatment processes, and is especially suitable for treatment of wastewater containing nitrogen oxides and organic pollutants.

Description

technical field

[0001] The invention belongs to the field of environmental microorganisms, and in particular relates to a denitrification bacterial strain and application thereof. The denitrification bacterial strain of the present invention can carry out denitrification with nitrous nitrogen as a nitrogen source, and can also remove COD at the same time, and is especially suitable for denitrification in the process of short-range nitrification and denitrification of ammonia-containing wastewater. Background technique

[0002] The traditional biological denitrification process mainly includes two processes of nitrification and denitrification. Nitrification is the premise of the denitrification process, and the denitrification process can truly remove nitrogen-containing compounds in wastewater. Because nitrifying bacteria have strong aerobic properties, the nitrification process is aerobic; while denitrifying bacteria are generally facultative bacteria, which use oxygen as ...
