Embodiment 1

[0045] Embodiment 1 The preparation of the composition containing Ningnanmycin

[0046] Inoculate the frozen Streptomyces noursii var. Xichang (purchased from Heilongjiang Biopesticide Engineering Technology Research Center) on a freshly prepared solid medium, at 28 ° C, 80% relative humidity, and under the condition of sterile air circulation Cultured for 16 days for rejuvenation, and the resulting strain spores were picked. Then produce mycelium, that is, to inoculate the spores of the strain on the freshly prepared solid medium, and culture it aerobically at 28°C, 80% relative humidity, and under the condition of sterile air circulation for 14 days, and the mycelium can be clearly seen produce. Carry out proliferation culture then, promptly use the first freshly prepared liquid medium to wash mycelia from the surface of the solid medium and enter a 1L Erlenmeyer flask, add the first freshly prepared liquid medium to supplement to a medium volume of 250ml, Incubate for 14 ...
