    Abstract: The invention provides a coating method for coating a surface of a substrate material with a biosurfactant. The method includes the following steps: modifying the biosurfactant to promote its reactivity with a silane linker; oxidising the surface of the substrate material; functionalising the surface of the substrate material with a silane linker; and reacting the modified biosurfactant with the functionalised surface. The biosurfactant becomes covalently bonded to the surface of the substrate material. The substrate material may be a polymer such as high-density polyethylene or polyvinyl chloride, or a ferrous metal such as stainless steel. The biosurfactant may be produced by one or more bacterial strains selected from the group consisting of Pseudomonas aeruginosa, Bacillus amyloliquefaciens and Serratia marcescens. The invention also provides articles of manufacture which include substrate materials that are at least partially coated with biosurfactants. The substrate materials and biosurfactants may be as described above.

    Abstract: A strain of Bacillus licheniformis (designated 'K-357') functions as an insecticide. Surprisingly, application of this single strain of B. licheniformis K-357 reduced nematode hatching and increased nematode mortality in vitro and reduced nematode counts and increased plant vigor and yield in cotton field trials. Nematicidal activity and cotton yield were compared for seed treated with B. licheniformis K-357 to in-furrow application of Aldicarb and Fluopyram, and seed treatment with Abamectin as nematicide. The nematicidal activity of the B. licheniformis K-357 was on par with, and in some cases superior to, that of the chemical treatments. The increases in cotton yield for seed treated with K-357 as nematicide were superior to that of both in-furrow application and seed treatment with the chemical nematicides. Corn seed treated with B. licheniformis K-357 in combination with chemical insecticides and fungicides had decreased root node injury in corn field trials heavily infested with corn rootworm.
