Abstract
|
|
|
|
The ethyl acetate extracts from the liquid cultures of Coriolus versicolor, Phellinus linteus, and Hericium erinaceus showed significant antibacterial activities against Escherichia coli K88, E. coli K99, E. coli 987P, and Salmonella typhimurium 14058 causing bacterial diarrhea in Korean house pigs and chicken. Of these extracts, Coriolus versicolor extract showed the highest antibacterial activity. In addition, these extracts also showed significant growth inhibition against Staphylococcus aureus CARM3230 and E. coli CARM1381 which are known as kanamycin and ampicillin-resistant strains. These results showed that the mushroom extracts could be developed as a livestock feed additives that can replace commercial antibiotics, and also could be good resources for the development of a new antibacterial agent.
