Verticillium leptobactrum W. Gams

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 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.
Growth conditions	28 ℃;5-7 days; Aerobic;
Storage conditions	2-8 ℃
morphology	Small filamentous fungi, with obvious colonies, white, dense hyphae and low flat, spreading to the edge of the plate, and light yellow on the back of the medium.
Sharing mode	Public welfare sharing

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.

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 cell recovery are reported as follows:

Item	test results
viability :	good viability， in 5days strain layer is obvious
colony morphology:	small filamentous fungi, with obvious colonies on comprehensive PDA medium, White, dense hyphae and low flat, spreading to the edge of the plate, the back of the medium is light yellow.
Conclusion:	good resurrection, no abnormal colony morphology, qualified ;
