Problems solved by technology

At present, there are more than 30 kinds of molds known to pollute feed, and about 200 kinds of mycotoxins produced. Mold pollution has brought great harm to the feed industry. Therefore, it is necessary to develop new, efficient, non-toxic and natural Antifungal agent for feed

Embodiment Construction

[0015] The present invention will be further described below with reference to the examples. The following examples are illustrative and not restrictive, and the protection scope of the present invention cannot be limited by the following examples.

[0016] A kind of actinomycetes TD-1 with anti-mildew pollution in grain feed and grain, classification name: Streptomycessp., its preservation number: CGMCC No.4666, preservation date: March 15, 2011, preservation Unit: General Microbiology Center of China Microorganism Culture Collection Management Committee, Preservation Address: No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing. When grown on No. 1 agar medium, the colonies were round, dry, powdery, wrinkled, and raised in the center. The aerial hyphae are pink to orange-red, and the basal filaments are orange-red. The hyphae are well-developed. The hyphae are closely interwoven, with a large number of branches and radials. Gram stain is positive, liquefied gelatin, ...

Abstract

The invention relates to actinomycetes for resisting contamination fungi in grain feeds and grains, which is characterized in that: the strain is named TD-1 and is classified and named Streptomyces sp., which is collected in China General Microbiological Culture Collection Center of Beijing on March 15, 2011 with the collection number of CGMCC No.4666. Autotrophic actinomyces for resisting growth of contamination fungi in the grain feeds and grains is separated and screened for the first time; and the strain has obvious inhibition effect on various fungi contaminating the grain feeds and grains, has obvious antagonism on aspergillus flavus, penicillium citrinum, fusarinm solani, aspergillus ochraceus, aspergillus oryzae, aspergillus nidulans, aspergillus niger, fusarium oxysporum, penicillium viridicatum and the like, can effectively prolong the retention period and improve the storing quality of the grain feeds and the grains, and lays a foundation for developing biological inhibitors for the fungi in the grain feeds and the grains.

Description

technical field [0001] The invention relates to the prevention and control of soil actinomycetes to the contaminating mould in grain feed and grain, in particular to an actinomycete which is resistant to the contamination mould in grain feed and grain. Background technique [0002] With the rapid development of my country's feed industry, the losses caused by mold to the grain feed industry and grain have gradually attracted people's attention. According to the estimates of the United Nations Food and Agriculture Organization, about 25% of the world's grains are currently contaminated with mycotoxins, causing economic losses of hundreds of billions of dollars every year. The average annual loss of feed in my country accounts for 20% of the total output, more than half of which is caused by mildew, especially in the southern region with a warm and humid climate. At present, it is known that there are more than 30 kinds of molds that pollute the feed, and about 200 kinds of m...
