NTG and UV mutagenesis Aspergillus composite protoplasts of rice protein decomposing bacteria

The same: that HeN a 4> HcN-U a】> HcA. . A 2> HcAs a 3-951. 2.3.2 flask solid neutral protease activity wiping song compared to solid medium after sterilization the flask were access to As. 3.951A. . A 2,[link widoczny dla zalogowanych], N-U A 1, N-4 slant cultured bacteria set 3O ℃ d8h, neutral determination of protease activity, results in Table 4. Table 4 Comparison of various strains of neutral protease activity results in Table 4 further indicates that; N-4 strain of the highest neutral protease activity than the original strain A. 2 high 32.6. Than As. 3.951 Variation of high 32.8.2.3.3 spine beam Aspergillus strain N-4 and the Yin Tong state down in the training process of comparing,[link widoczny dla zalogowanych], on the original strain A. o - 2, N-4 mutant colony morphology and growth were observed: in the soybean milk and the police's slant on the slope. N-4 colony morphology and strain A. o_2's no difference but the rapid growth of N-4. The colony than A. 2 appeared earlier 8h. Tangled in the casein plate,[link widoczny dla zalogowanych], N-4 production of spores and spore full time slightly earlier. So is a production of N-4 mutant. 2.4 Experimental conditions for enzyme production strains only in a good condition suitable for cultivation in order to show its best performance. Therefore, N-4 mutant enzyme production conditions of the preliminary discussion, the results shown in Table 5. Table 5N-4 mutant enzyme production conditions in Table 5 that: (1) N-4 enzyme production peaked in the first 48h. (2) training at the same time, the rice residue; when wheat bran = 2.1,[link widoczny dla zalogowanych], N-4 of the neutral protease is the highest. Hubei Agricultural College * 54 * Volume 3 ¨ Summary (1) N-4 for the production of mutant strains,[link widoczny dla zalogowanych], the morphology and original strain. o-2 no significant difference. (2) N A 4 and As. 3.951 compared with the neutral protease activity increased 32.8%, the growth of strong, fast, easy to culture in the production of a certain value. (3) N-4 mutant at 30 More articles related to topics：
