  • Patent number: 8957129
    Abstract: Disclosed is an aqueous coating composition including at least one latex polymer derived from at least one monomer copolymerized or blended with a rhamnolipid and/or sophorolipid biosurfactant. Also provided is an aqueous architectural coating composition including at least one latex polymer derived from at least one monomer copolymerized or blended with a rhamnolipid and/or sophorolipid biosurfactant, at least one pigment, and water. Also provided is a method of preparing an aqueous architectural coating composition such as a latex paint including the above components.

  • Patent number: 5665354
    Abstract: A Bacillus licheniformis producing an antifungal principle active against a wide variety of plant pathogenic fungi has been isolated. The microorganism was obtained from the rhizosphere of perennial ryegrass (Lolium perenne L.). The type isolate, strain PR1-36a, is particularly antagonistic to filamentous fungi, including Rhizoctonia and Magnaporthe. The microorganism was shown to be effective as a biocontrol agent for control of Fusarium seedling blight in corn. The antifungal principle produced by the microorganism is diffusible and may be purified by acid precipitation of the culture fluid, followed by ethanol extraction. The antifungal principle is fungistatic against several diverse species of fungi, and shows particularly strong activity against filamentous fungi, many of which are serious plant pathogens.
