| 摘 要： | 从6株霉菌中筛选出具有较强生淀粉分解能力的黑曲霉、米曲霉、宇佐美曲霉和少根根霉，并进行混株发酵，试验结果表明，所得粗酶分解生淀粉能力显著提高。最低的D组提高5．43％，最高的E组提高10．0％，而且菌株的种属会明显影响分解生淀粉的能力。

| Abstract: | Four strains including Aspergillus niger,Aspergillus oryzae,Aspergillus usamii,and Rhizopus arrhizus,which had strong raw starch-digesting capability,were screened from 6 Aspergillus strains.Then mix strains fermentation were carried out.The experimental results indicated that the raw starch-digesting capability of the produced crude enzyme improved evidently(D group increased by 5.43 %(as the lowest),E group increased by 10.0 %(as the highest)).Besides,the strain species would influence raw starch-digesting capability markedly. |
