Quantitative strain of Enterobacter cloacae
Culture medium Nutritional gravy medium (NA/NB): beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (without liquid medium), distilled water 1.0L,pH 7.0. Sterilization at 121 ℃ for 15min. [Note] Adding 5 mg MnSO4 · H2O to culture Bacillus is beneficial to produce spores.
Subculture procedure (1) According to the culture conditions, the bacteria are first cultured into a bacterial suspension; ② Measure the absorbance of the bacterial suspension and calculate the initial concentration of the bacterial suspension according to the standard formula; (3) The initial concentration multiplied by the survival rate is the actual concentration after freeze-drying; (4) Dilute the bacterial suspension according to the actual concentration after freeze-drying to obtain the target concentration, and then subpack and freeze-dry;
Growth conditions 30 ℃;18-24h; Aerobic;
Storage conditions -20 ℃
morphology Pale yellow, raised, moist, bright, G-bacilli
Sharing mode Public welfare sharing
