Mucor racemosus

No.: 189210

Storage conditions: 2~8 ℃

Product format: freeze dried,200ul

Validity period: 24 months

Biosafety level: 1, handle in ultra-clear table or safety cabinet

Receiving notice: if any abnormality is found on the day of receipt, please contact the customer service within 24 hours. If it is overdue, it is deemed that the bacteria are well. The freeze dried culture shall be used up once and shall not be retained. The bacterial viability will resume after 1-2 generation of recovery and can be used normally. Please operate in strict accordance with this instruction, otherwise the replacement of bacteria are not be available in case of aberrant growth and loss of viability.

Growth conditions:25 ℃, aerobic, integrated PDA. Comprehensive PDA:20% potato juice 1L, glucose 20g ,KH2PO4 3g, MgSO4.7H2O 1.5g, thiamine trace, agar 15g,pH natural.

Recovery steps:

(1)Prepare 2 pieces of PDA plates or 2 agar slants;

(2)Open the ampoule 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 sterile water into the freeze dried ampoule, make it fully dissolved, and distribute the solution to the plates well in 200ul/plate; or transfer appropriate solution to
the agar slant.
(4)Place the plates uprightly and agar slant obliquely under the above culture conditions for 5-7 days. Or contact our technicians for the inoculation of agar slant - filamentous fungi.

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

item	test result
viability	good viability,in 4 days plate colony is obvious
colony morphology:	The morphology of bacteria is obviously visible in the integrated PDA agar medium, The colony is loose flocculent, initially white, then light yellow to brown gray, and grows rapidly.
conclusion:	good viability, no abnormality in colony morphology, completely consistent with the above figure, qualified
