Abstract

The invention provides novel polypeptin having potential value of biological control and medical applications, and a preparation method and application thereof. The structure of the polypeptin is shown as a formula (I). The invention has the advantages of providing the polypeptin which has the toxicity lower than that of polymyxin B and has the potential value of biological control and medical applications, and the preparation method and the application thereof. In vitro experiments show that the compound has the obvious effect of inhibiting all the tested gram-positive bacterium, gram-negative bacterium and fungi. Disk-culturing experiments show that the compound has certain effect of preventing and treating various fungal plant diseases and particularly has obvious effects of preventing and treating rice sheath blight.

Description

(1) Technical field

[0001] The present invention relates to a novel polypeptide bacterin and its preparation and application. (2) Background technology

[0002] Globally, plant diseases caused by pathogenic bacteria and pests are one of the main causes of agricultural losses. For half a century, people have mainly used chemical pesticides to prevent and control these diseases, and have achieved remarkable results. However, many chemical pesticides have the characteristics of high toxicity, high residue, and refractory degradation. With the widespread use of these pesticides, environmental pollution has become increasingly serious, ecological balance has been destroyed, and the health of humans and livestock has also been greatly threatened. In addition, with the continuous emergence of drug-resistant bacteria and pests, the control efficiency of chemical pesticides has gradually declined. These problems have attracted people's attention, prompting people to look for a new c...
