Abstract:
The antimicrobial activity of hop resins against Streptococcus salivarius , Staphylococcus aureus (two strains), Bacillus megaterium , Escherichia coli B, and Bacillus subtilis was investigated. However, resistance development was carried out on Streptococcus salivarius , Staphylococcus aureus (two strains), and Bacillus megaterium . The two hop resins used were iso-alpha resin and beta resin. Prior to resistance development, S. salivarius , S. aureus , and B. megaterium were all inhibited by the iso-alpha-hop resin in the 0.01 to 0.03% range. The beta-hop resin which, according to the literature, is more active than the iso-alpha resin initially inhibited these organisms at the 0.003 to 0.01% concentrations. The ease of resistance development varied between the different microbes, B. megaterium being the least prone to develop resistance.
