Abstract
|
|
|
The aim of this study is to evaluate the interactions between the mixture of resin fractionated ethanol extract of three plant species (Eucalyptus sp., Yucca sp., and Melaleuca alternifolia) and antimicrobial substances produced by bacteria (Paenibacillus elgii DS381, Burkholderia gladioli DS518, Streptomyces lienomycini DS620, and Paenibacillus elgii DS1515) against diverse microorganisms including human pathogens and mycotoxigenic fungi.
The plant fraction mixture exhibited low minimum inhibitory concentration (0.156~0.625 mg/ml) on target microorganisms.
In the checkboard assay, combinations of the antimicrobial substances from plants and bacteria displayed synergistic effects against each target organism [0 < fractional inhibitory concentration index < 0.75]. Most combinations of the antimicrobial substances reduced more than 105 cell/ml of bacteria and yeast during 24 h incubation. Moreover, combinations of the antimicrobial substances showed fungal spore degradation (~88.8%) and spore germination inhibition (~100%). The combination of this plant fraction mixture and antimicrobial substances from bacteria may be utilized to inhibit human pathogens and mycotoxigenic fungi.
