Title:
NEW TYPE OF EFFICIENT FLOCCULATION DENITRIFYING BACTERIA AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/017398
Kind Code:
A1
Abstract:
Provided are a new type of efficient flocculation denitrifying bacteria and the use thereof. Thauera sp. JM12B12 is separated and screened from water in a Penaeus vannamei culture pond, and was preserved in Guangdong Microbial Culture Collection Center (GDMCC) on June 27, 2023, the address thereof being Building 59, Yard 100, Xianlie Middle Road, Yuexiu District, Guangzhou City, Guangdong Province, and the preservation number being GDMCC No. 63587. Thauera sp. JM12B12 is separated from water in a Penaeus vannamei culture pond, namely, the removal rates of nitrate nitrogen and nitrite nitrogen by the strain are both 100% when the carbon-nitrogen ratio is 5-20. In addition, the strain also has an efficient flocculation function, namely when nitrate nitrogen is removed, the flocculation efficiency of the bacteria cells thereof and the supernatant is 90.6% and 90.1% respectively. The new efficient flocculation denitrifying bacteria JM12B12 provided has important application value in denitrification and removal of solid suspended matter of wastewater exceeding the standard of nitrogen content, thereby providing a new microbial material for water environment protection.
