Study of kinetic antibacterial activities of QJ2 against pathogen W-1 was tested by viable bacteria counts and absorbency at 600nm: 106～ 107 cfu/mL cells of W-1 began to decrease in 15 min after mixing with CFS(cell free-supernatant) of QJ2; the bacterial counts decreased to a minimum at 4h, and the numbers of bacteria began to increase after 6h. The cells of QJ2 did not show any sensitivity to its inhibitory substances in CFS. The size of active molecule in the CFS of QJ2 was smaller than 8000 Da by measuring the inhibitory activities of the fluid inside and outside the dialysis cellulose tubing. QJ2 was identified as Flavobacterium ordaratum by traditional morphological and biochemical method and API-20 identification system.

并对拮抗菌QJ2的拮抗作用进行了研究，结果为：QJ2有广泛的弧菌抗菌谱，对37株弧菌的抗菌阳性率达到89.2%(33/37)；用活菌平板计数法和O.D.600nm研究了QJ2培养物的去细胞上清液与病原菌W-1的作用动力学，15min时W-1的细菌数便开始减少，4h时细菌数最少，6h后开始增加，而对照组的细菌数呈逐渐上升趋势；QJ2对自身的拮抗物质不敏感；QJ2抗性物质的分子量不大于8000Da；经常规生理生化方法和API-20细菌快速鉴定系统鉴定，QJ2为气味黄杆菌。
