| 摘 要： | 采用对峙培养法,检测分离于土壤中的链霉菌TD-1代谢产物对饲料中污染霉菌构巢曲霉（Aspergillus nidulans）、纯绿青霉（Penicillium verrucosum）、赭曲霉（Aspergillus ochraceus）、黄曲霉（Aspergillus flavus）、黑曲霉（Aspergillus niger）、米曲霉（Aspergillus oryzae）、茄腐镰刀菌（Fusarium solani）、桔青霉（Penicillum citrinum）、串珠镰刀菌（Fusarium moniliforme）的抑菌活性,结果表明：TD-1菌株代谢产物对以上霉菌具有较强的抑制作用,抑菌带宽度为10 mm左右.通过TD-1菌株的代谢过程曲线发现,该菌株发酵至第6 d抑菌率达90%左右.稳定性试验结果显示：该菌株所产生的活性物质具有较好的耐热性、耐酸碱性、抗紫外辐射能力.

| Abstract: | Metabolites of Streptomyces sp. TD-1 were reported with obvious inhibiting effects to Fusarium moniliforme, AspergiUus nidulans, PenicilIium verrucosum, Aspergillus ochraceus, Aspergillus flavus, As- pergilltts niger, Aspergillus oryzae, Fusarium solani and Penicillt~m citrlnum with the size of inhibition zone of about 10 ram. The metabolic chart of growth process of TD-1 strain showed that the growth a- mounted to the maximum, and the inhibition rates reached to 90% at the 6th day. Stability test showed that the antimicrobial compounds produced by TD-1 strain had good thermo and pH stability, and strong anti-UV ability. |
