Novel Oil Having Antibacterial Activity

Liamocins produced by certain strains of the fungus Aureobasidium pullulan have anti-bacterial activity with specificity for Streptococcus spp., Enterococcus spp., and Bacillus spp. The invention includes methods of using the liamocins and compositions containing modified liamocins to kill bacteria. This invention also relates to methods to produce modified liamocins with specific head groups.


•Liamocins are chemically different than conventional antibiotics, and cross-resistance should be minimal
•May be effective for Streptococcus infections that do not respond to conventional antibiotic therapy
•The liamocins are produced from low-cost agricultural biomass substrates, particularly pretreated wheat straw


•Dairy cattle dips for prevention of mastitis caused by Streptococcus sp.
•Topical antibacterial treatments
•In more refined forms, the pharmacologically active component(s) of the liamocins have potential to be incorporated into injectable or oral medicines
