BeNa Culture Collection
Culture medium | CDA: 3g of sodium nitrate, 1g of dipotassium hydrogen phosphate, 0.5g of magnesium sulfate, 0.5g of potassium chloride, 0.01g of ferrous sulfate, 30g of sucrose, 15g of agar, 1.0L of distilled water and 6.2±0.2 of pH. Sterilization at 121 ℃ for 15min. |
Subculture procedure | (1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) Open it in the safety 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. |

Aspergillus ochraceus
Storage conditions : 2~8 ℃
No. : 336184
Product format: freeze dried, 200ul
Validity period : 24 months
Biosafety level :1 , handle in ultra-clean 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. Handling instructions agar slant and suspension liquid is enclosed. Please operate in strict accordance with this instruction, otherwise the replacement of bacteria are not be available in case of aberrant growth and lose of viability.
Growth conditions :25-28 ℃, 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 results |
viability | good viability, in 5 days strain layer is obvious |
colony morphology | The morphology of the bacteria is obviously visible in the integrated PDA agar medium. The colony is white at the beginning, and orange spores are produced later. The reverse surface of the colony is yellowish brown, wrinkled, and spreads on the surface of the plate. |
conclusion | good viability, no abnormal colony morphology, completely consistent with the above figure, qualified |
