Several species of Aspergillus fungi produce highly toxic aflatoxins that upon contaminating corn fields create huge losses in yield of useable grain. One strain of aspergillus known as K49, does not produce aflatoxins and is quite adept at excluding its toxic cousins via biocompetitive exclusion.
A team of scientists is working to use this strain of fungus encapsulated in small cornstarch bioplastic containers to battle the growth of toxic aspergillus fungi in corn fields. These small bioplastic “bullets” keep small rodents and birds from eating the fungi before it has an opportunity to release spores and disperse, and are also biodegradable.
To learn more about how K49 might be dispersed and how the use of the bioplastic “bullets” may help deliver other soil-applied fungi, you can read more here.
