Quantitative strain of Clostridium sporogenes

Culture medium	Columbia blood plate (CA-B): casein pancreatin digest 10.0g, cardiopancreatin digest 3.0g, corn starch 1.0g, meat gastric enzyme digest 5.0g, yeast extract 5.0g, sodium chloride 5.0, agar 20.0g, distilled water 1.0L,pH 7.3±0.2. After sterilization at 121 ℃ for 15min, cool to 55 ℃, add 5% sterile defibrated sheep blood, shake well, pour the plate and cool it for later use.
Subculture procedure	(1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) open it in the biosafety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps; (3) draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; (4) inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; ⑤ Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.
Growth conditions	37 ℃;18-24h; Anaerobic;
Growth characteristics	G +, cell straight rod-shaped, 0.73 × 1.46~3.33 μm. Mostly a single arrangement. The spores are oval, subterminal, and the spores are enlarged. After the formation of spores, the bacteria quickly decomposed, leaving only spores.
Storage conditions	-20 ℃
morphology	The colony diameter is 1-2mm, round, with neat edges, opaque, white on the front, convex in the middle, bright surface, smooth surface, moist texture, easy to stir up, G + (blue-purple), bacilli, purity: pure
application	Research; Analytical testing. Teaching and research. "Technical Specifications for Disinfection" Bacteria for Testing Sterilization Effect of Traditional Chinese Medicine Therapeutics, "GB/T 4789.12-2003 Clostridium botulinum and Botulinum Toxin Test" Positive Control Strain, Quality Control Strain of Chinese Pharmacopoeia, 2015 Edition. 2020 Edition Pharmacopoeia-"General Principles 1100 Biological Inspection Method" for tested strains of bacteria in pharmacopoeia, medium "sensitivity inspection" for tested strains, "method applicability test" for tested strains, "medium applicability test and control bacteria test method applicability test" for tested strains
Sharing mode	Public welfare sharing
