摘要
液体培养细菌后,分别测定培养液、培养液沉淀+无菌盐水的吸光度,结果存在明显差异。采用稀释平板法和显微计数法测定了培养液中细菌数量,并推导出嗜水气单胞菌活菌数与吸光度的关系为logI0/I=6.848×10-25·C。
Optical density （ OD ） of cultured solution, sediment of cultured solution, and sterile brine were tested respectively after bacteria were culture in liquid. The results were significantly different. The number of bacteria was counted with dilute plate method under microscope. Relationship between live bacteria of Aeromonas hydrophila and 019 was deduced as logI0/I = 6.848×10^-25·C.
