Abstract

The invention provides biologically active compositions comprising oligosaccharides, and which are produced by growing a fungal culture, and are at least partially purified for use. The compositions of the invention have antibacterial, antifungal and nematicidal activity, and are thus useful to reduce the impact of such pathogens on growing plants, to reduce the occurrence of such pathogens on surfaces and in substances, and to treat infections caused by such pathogens in animals and humans. The invention also provides methods for producing such compositions from certain fungal cultures.

Description

[0001] related application

[0002] This application claims priority to US Provisional Application No. 60 / 704,824, filed August 1, 2005, which is hereby incorporated by reference in its entirety. technical field

[0003] The present invention relates to novel compositions having activity against microorganisms and other pathogens; said compositions are produced from certain species of Basidiomycetes fungi. The present invention provides sugar-containing compositions having antimicrobial activity against various pathogenic organisms, including nematodes, fungi and bacteria. The invention also provides culture conditions capable of increasing the basidiomycete fungi to produce biologically active substances, and one of the methods for using these compositions to protect plants from plant pathogens. Background technique

[0004] Some fungi are known to be toxic or hallucinogenic. It has been reported that metabolites produced by some fungi have antimicrobial activity against...
