  • Publication number: 20230127686
    Abstract: Provided herein are fatty-ammonium salt/starch inclusion complexes comprising one or more of a variety of fatty amines. Such complexes can be combined with film-forming agents, such as poly(vinyl) alcohol (PVOH) and plasticizing agents. The inclusion complexes of the present invention can be utilized as antimicrobial agents, preventing microbial growth on organic and inorganic surfaces. In specific embodiments, inclusion complexes of the present invention are applied to vegetable or fruit surfaces in order to impede microbial growth. Inclusion complexes of the present invention can be applied to wood in order to impede microbial growth and insect consumption and to wound dressings.

  • Patent number: 8628764
    Abstract: Bacterial compositions effective for inhibiting fungal diseases of potatoes and/or potato sprouting are produced by co-culture of two or more of Pseudomonas fluorescens (NRRL B-21133), Pseudomonas fluorescens biovar (NRRL B-21053), Pseudomonas fluorescens (NRRL B-21102) and Enterobacter cloacae (NRRL B-21050). Compositions produced by co-culture of these bacteria together in the same culture medium are significantly more effective for inhibiting fungi-induced diseases of potatoes and/or inhibiting sprouting of potatoes, than blends or mixtures of the same bacteria cultured separately.

  • Patent number: 8241889
    Abstract: Strains of Cryptococcus flavescens which are superior antagonists of F. graminearum for suppression and control of FHB in cereals, particularly in wheat and barley, are described. The strains are prothioconazole tolerant variants of previously described C. flavescens OH 182.9 (NRRL Y-30216).

  • Patent number: 6107247
    Abstract: Sprouting in stored potatoes is suppressed with sprout control agents of bacterial origin. These agents are typically applied to the potato surfaces as whole culture broths and they prevent softening and necrosis of the tuber. In a preferred embodiment of the invention, selected isolates also have the secondary effect of Fusarium dry rot control.
