A comprehensive bacterial analysis was completed using mash collected from an operating fuel ethanol facility. Minimum Inhibitory Concentration (MIC) testing was conducted for various levels of Lactrol and two competitive antimicrobial products.

• The data represents whole-mash incubation, which likely includes multiple bacterial strains. The readings were analyzed after 24 hours of incubation.
• Performance was measured by the bacteria’s ability to grow in the presence of the antimicrobial. The scale below represents a percentage of bacterial growth. 100 percent growth indicates that the antimicrobial products are not effective, while 0 percent growth indicates total control by the antimicrobial.
• Lactrol showed superior control over bacterial growth in comparison to competitive products. Even at low dose rates, Lactrol greatly impacts bacterial growth.
