Much progress was made in the identification and development biocides to control various molds and plant diseases. Most commercial pesticides and biocides are carcinogens, or toxic to non-target animals or wildlife. As an example, methylbromide is used widely as a soil fumigant and to treat microbial infections after harvest. The toxicity of methylbromide to humans and the negative effects on the environment will eventually lead to its discontinuation. Recent efforts have been focused on the identification and development natural or biomimetic compounds that demonstrate comparable antimicrobial/pesticidal effects.
One approach is to look at endophytes, and their associated volatile byproducts. In the art, endophytes are microorganisms that reside in the interstitial space of living plant tissues. They are not generally considered parasitic. Endophytes associated with rain forest plants are of particular interest due to their antibiotic-like volatile by-products. It has been demonstrated that several members of the Muscodor family (M. albus M. roseus, and M. viigenus) produce volatile by-products with antibiotic or insecticidal properties. The by-products of each species include naphthalene or azulene. These compounds can be toxic, or unhealthy in other ways, and their mixtures with other by-product components are not acceptable for many end use applications. There is a continuing search to find natural compositions, and biomimetic compositions that are free of such compounds and have effective anti-microbial properties.
In view of the above, it is the object of this invention to provide flavors that have antimicrobial components and/or methods of their use. This will overcome various shortcomings and deficiencies of the prior arts, including those described above. It will be clear to those in the know that certain aspects of this invention may meet certain objectives while other aspects may meet other objectives. It is possible that not all aspects of the invention will meet each objective equally. The following objectives can be viewed alternatively with respect to one aspect of the invention.
It can be the object of the invention to provide Muscodor species, and a volatile byproduct thereof, without naphthalene or azulene related compounds (non-GRAS compound), in conjunction with a method for the prevention, inhibiting and/or eradication microbial infections.
It can also be an object of the invention to provide a method that combines a species, or strain, and a volatile by-product associated with it in conjunction with non-indigenous media or substrates for use against microbial infections.
