BeNa Culture Collection
Culture medium | Potato Glucose Agar (PDA): Potato Boiled Solution 1.0L, Glucose 20.0g, Agar 15.0g, Natural pH. Sterilization at 121 ℃ for 15min. Potato boiling liquid: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect the filtrate to a constant volume of 1.0L. |
Subculture procedure | (1) Prepare 1-2 pieces of the plate; (2) sterilize the surface of the plate and open it in biosafety cabinet; (3) Absorb 1-3ml of sterile water into the plate, scrape the bacterial lawn back and forth on the surface of the plate with a sterile spreader to make a bacterial suspension; (4) suck the bacteria suspension with a pasteur pipette, dispense it into a fresh plate evenly. (5) put the plates under the growth conditions. |

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, PDA,5-7 days. PDA: potato boiling solution 1.0L, glucose 20.0g, agar 15.0g (without liquid medium), natural pH. Sterilization at 121 ℃ for 15min. Potato boiling liquid: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect the filtrate to a constant volume of 1.0L.
Recovery steps:
(1)Prepare 1-2 pieces of PDA plates;
(2)Sterilize the surface of test tube for the agar slant, open it in the biosafety cabinet;
(3)Cut into the pieces with aseptic inoculation hoe and inoculation shovel (see attached page). the size of square pieces is 0.5 × 0.5cm2;
(4)Lay flat the small pieces to the center of the agar plate;
(5)Put the plates under the above culture conditions, and the strains can be used when they grow.
Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:
Item | test results |
viability | good viability, in 5-7 days strain layer is obvious |
colony morphology | small filamentous fungi have obvious colonies on PDA medium, white hyphae, fluffy, spreading and growing to concentric circles on the edge of the plate. |
conclusion | good viability, no abnormality in colony morphology, |
