Clostridium beijerinckii

Subculture procedure	① Prepare one test tube containing 5-10 mL of liquid culture medium and two plates; ② Open the safety cabinet, burn the top with an alcohol lamp, quickly drip sterile water to break it, and then use tweezers to crush it; ③ Transfer 0.5mL of liquid culture medium into a freeze-drying tube, dissolve it thoroughly, and then transfer it back into the liquid test tube, mixing well; ④ Transfer 0.2mL of bacterial suspension into a Agar plate, apply evenly, and repeat twice to obtain two plates; ⑤ Place all liquid test tubes and plates under the above cultivation conditions, and the bacterial strains can be used once they grow.

Dry powder shall not be retained after one use, and can be used after activation for 1~2 generations. please refer to the attached page for the use of flat plate and bacterial liquid. Please activate in strict accordance with this instruction, otherwise the replacement service will not be provided if the strain is abnormal and inactivated.

Growth conditions:37 ℃, anaerobic, Colombian blood plate (ready to use),48-72h ;

Recovery steps:

① Prepare the above flat plate 1-2 block (put it in anaerobic environment for 24 hours in advance);

② Open it in the safety cabinet, burn the top with an alcohol lamp, quickly drop sterile water to break it, and then break it with tweezers;

③ Suck 0.5mL of sterile water and put it into the freeze-drying tube. after fully dissolving the bacterial powder, put it into the plate 200μL/piece, coated evenly;

④ Place the plate under the above culture conditions, and the strain can be used when it grows out.

Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:

Item	test results
viability:	good viability， in 48hours strain layer is obvious;colony is typical on the streaked plate
Colony morphology: (pictured above)	Size: 1-2mm Shape: Round Edge: Irregular Transparency: Opaque Color: White Protuberance: Middle convex surface: rough texture: moist and easy to stir
conclusion: good viability, no abnormal colony morphology, qualified
