  • Enteric-coated sodium metabisulfite livestock feed additive for vomitoxin detoxification
    Patent number: 9980910
    Abstract: A livestock feed supplement in which a core particle containing sodium metabisulfite and at least one binder is enrobed with an enteric coating, wherein the thickness and composition of the coating protects the sodium metabisulfite from decomposition to sulfur dioxide in an aqueous acid stomach environment. Also disclosed are a method of delivering sodium metabisulfite to the lower gastrointestinal tract of an animal, and a method of delivering an antidote to relieve the toxic effect of vomitoxin in an animal, by administering to the animal the livestock feed supplement.
    Type: Grant

  • DMI1 gene encodes a protein that is required for the early steps of bacterial and fungal symbioses
    Patent number: 7205450
    Abstract: The invention relates to isolated DMI11 genes from Medicago truncatula which play a major role both in the early steps of Nod factor signaling that trigger several key developmental responses in the host plant and in the establishment of mycorrhizal symbiosis. The invention also relates to transgenic plants and plant cells expressing the DMI1 protein for increased root nodulation, and methods for transforming plants with a M. truncatula DMI1 gene.

  • Hydroxypropylmethylcellulose
    Patent number: 4696762
    Abstract: A process is used to increase the rate and quality of dispersion of hydroxypropylmethylcellulose (HPMC) in water. The HPMC is dry blended in a fluidized bed by intermittently spraying the HPMC particles with a liquid spray while the particles are in the fluidized state causing the surfaces of the particles to become tacky and the particles to stick to each other. The particles are permitted to dry between spraying intervals and the spraying and drying is continued until agglomerated particles are formed having a moisture content of less than 25% by weight of the agglomerated particle.

  • Product and process for improving the dispersion of a vegetable gum in water
    Patent number: 4557938
    Abstract: A process is used to increase the rate and quality of dispersion of a vegetable gum in water. The vegetable gum is dry blended with a food grade particulate carrier, such as starch, in a fluidized bed. The mixture of the carrier and the vegetable gum is intermittently sprayed sufficiently to wet the surfaces of the carrier and vegetable gum. During the spraying, the particles become tacky and stick to each other to form agglomerated particles. Between the intermittent spraying, the particles are dried by the air fluidizing the bed. The intermittent spraying and drying is continued until agglomerated vegetable gum/carrier particles are formed having a moisture content below approximately 25% by weight.
