purple silk membrane bacteria

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 PDA 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 for 5-7 days.
Growth conditions	Culture temperature 28 ℃; Culture time 5-7 days; Aerobic atmosphere;
Storage conditions	2-8 ℃
morphology	Small filamentous fungi, obviously visible on integrated PDA agar medium, colonies pink-white, dry, vigorous, in culture The base surface spreads and does not produce spores.
Sharing mode	Public welfare sharing

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 agar plates under the above culture conditions for cultivation 5-7days

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

item	test results
viability:	good viability,in 7 days plate colony is obvious
colony morphology:	small filamentous fungi are obviously visible on integrated PDA agar medium, colonies are pink-white, dry, vigorous, spread on the surface of the culture medium and do not produce spores.
conclusion:	good viability, no abnormal colony morphology, completely consistent with the above figure, qualified
