Technical Specifications

OrganismQuantitative strains of bacillus subtilis
Material TypeMicrobiological Quality Control
Preservation FormFreeze dried pellet
Morphological CharacteristicsThe diameter of the colony is 1-2mm, circular, with neat edges, opaque, gray white on the front, raised in the middle, smooth on the surface, moist texture, easy to pick up, G+(blue purple), Bacillus
Culture Method① Cultivate the bacteria into a bacterial suspension according to the cultivation conditions first; ② Measure the absorbance of bacterial suspension and calculate the initial concentration of bacterial suspension according to the standard formula; ③ The actual concentration after freeze-drying is obtained by multiplying the initial concentration by the survival rate; ④ Dilute the bacterial suspension according to the actual concentration after freeze-drying to obtain the target concentration, and then divide and freeze dry it
