Sterility test; neomycin, cefactor, amikacin, kanamycin, cefoxitin, cefazolin, nafcillin, neogreen, vancomycin, lincomycin, penicillin, tobramycin , neomycin b, spiramycin, gramicidin, cefotaxime, cephalexin, cephalosporin, mithramycin, gentamicin, doxycycline, methicillin, cefotaxazole, cephalosporin Determination of leucine, cloxacillin, cycloserine, erythromycin, tetracycline, methicillin cephalosporin, diclofenac, dimecycline, oxytetracycline, oxytetracycline, chlortetracycline; Susceptibility testing of natamycin, clindamycin, streptomycin and tetracycline.

Medium
Nutritional gravy agar: peptone 5.0 g, beef extract 3.0 g, NaCl 5.0 g, agar 15.0 g, distilled water 1.0 L, pH 7.0. [Note] When 5mg MnSO4·H2O is added to the culture of Bacillus, it is beneficial to produce spores. 

Growth conditions
37 ° C, aerobic

Growth characteristics
G+ cocci, arranged in a single, paired, irregular pile. No spores. Negative ornithine decarboxylase, fermenting glucose, maltose, lactose, sucrose, producing acid, not producing gas, fermenting mannitol. The methyl red reaction was positive, and the volt-Pulse test was weakly positive. A transparent hemolysis ring forms around the blood plate colonies. Produces golden yellow pigment. Facultative anaerobic, optimal pH 7.0-7.5.

Storage condition

4 ° C, protected from light and cold.

use of Quality Control Strains:

Sterility examination, microbiological limit inspection of non-sterile products, and bacteriostatic efficacy check.

Media suitability test, growth promotion test, sensitivity test, method suitability test, positive control, etc.
