Bacillus flexus R29-2 from deep sea, micro-ecological preparation and application thereof

The invention relates to a bacillus flexus strain. The preservation name of the strain is bacillus flexus R29-2, the preservation unit is China General Microbiological Culture Collection Center, and the preservation number is CGMCC No.18731. The strain is derived from the west Pacific Caroline seamount, and is a circular beige smooth opaque bacterial colony in an LB agar culture medium. The strainis in a short rod shape under a microscope, and gram staining is positive. The strain has a good antibacterial effect on gram-positive bacteria such as staphylococcus aureus, streptococcus agalactiae, enterococcus faecalis and bacillus cereus, and can effectively increase the survival rate of poultry, reduce the feed conversion ratio and improve the disease resistance of aquaculture animals whenbeing prepared into a micro-ecological preparation and serving as a feed additive in poultry breeding and aquaculture. 本发明涉及一株弯曲芽孢杆菌菌株，该菌株的保藏名称为：弯曲芽孢杆菌R29-2，保藏单位：中国微生物菌种保藏管理委员会普通微生物中心，保藏编号:CGMCC No.18731。该菌株来源于西太平洋卡罗琳海山，在LB琼脂培
