This paper studies the extracellular products of Vibrio fluvialis Ⅱ,the results show that the extracellular products include amylase, gelatinase, lipase, casease, haemolysin, but don t contain lecithinase and urease. 利用杯碟法研究了河流弧菌Ⅱ的胞外产物。4...
该试剂盒正是基于冷冻干燥的发光细菌——费氏弧菌(Vibrio fischeri)作为生物感应器。在发光细菌复苏后,暴露到被检测样品前后分别检测发光强度,计算相对发光强度的损失百分比,从而得出光抑制率,并根据此值范围划分毒性等级。发光细菌毒性试验的灵敏度与标准的毒性评价试验有很好的一致性;且与鱼类96h急性毒性试验相关性费氏弧...
