BeNa Culture Collection
Culture medium | Comprehensive PDA agar (CPDA): potato boil 1.0L, glucose 20.0g,KH2PO4 3.0g,MgSO4 · 7H2O 1.5g, vitamin B1 trace, agar 20.0g,pH 6.0±0.2. 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. |
Growth conditions | 28 ℃;5-7 days; Aerobic |
Storage conditions | 2-8 ℃ |
morphology | Small filamentous fungi, with obvious colonies, white, dense and vigorous hyphae on the integrated PDA medium, spreading and growing to the edge of the plate, and the back of the medium was khaki yellow. |
Separation substrate | brown planthopper, Nilaparvata lugens |
Sharing mode | Public welfare sharing |
Erynia delphacis
Storage conditions: 2~8 ℃
No. : 338162
Product format: agar slant in 14mm test tube
Validity period : growing culture, in 30 dyas
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 agar slant can be used directly. In principle, it can be used many times without contamination within the validity period, but viability will gradually decrease with time. 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 :28 ℃, aerobic, integrated PDA,5-7 days. Comprehensive PDA: potato boiling solution 1.0L, glucose 20.0g,KH2PO4 3.0g,MgSO4·7H2O 1.5g, vitamin B1 trace, agar 20.0g,pH 6.0±0.2. Sterilization at 121 ℃ for 15min. Potato boiling solution: weigh 200g of peeled potato pieces, boil in boiling water for 30min, and collect 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 days strain layer is obvious |
colony morphology: (above) |
small filamentous fungi with obvious colonies on comprehensive PDA medium, White, dense and vigorous hyphae, spreading to the edge of the plate, khaki on the back of the medium |
Conclusion: | good viability, no abnormal colony morphology, qualified; |
