  • Publication number: 20180310567
    Abstract: A non-hazardous bio-pesticide, nematicide, and plant nutrient composition includes a mechanical insecticide and a biofertilizer and may further include a binder. The composition provides a natural pesticide defense when introduced at or near the plant rhizosphere, controlling and killing plant pathogenic nematodes and nematode larvae and introducing plant nutrients and growth promoters into the soil to promote water conservation.

  • Patent number: 6338866
    Abstract: Methods are disclosed for using a waste product which remains when various types of algae (such as Crypthecodinium cohnii) or non-yeast fungi (such as Mortierella alpina) are used to manufacture essential fatty acids. This waste product is a biomass which includes the cell carcasses that remain after one or more essential fatty acids (such as docosahexaenoic acid, DHA) have been extracted from lysed (ruptured) cells. In one preferred embodiment which forms a biscuit-type treat for dogs or cats, algal biomass is mixed with a combination of brewer's yeast, a grain product such as whole wheat, and burnt residues that collect on the interior walls of drying vessels used for spray-drying of yeast extracts. These ingredients are mixed with water to form a dough-like substance, which is made into a desired shape for a dog, cat, or other pet treat. The dough is then cooked to form a pleasant-smelling biscuit-type treat which dogs and cats find highly appealing.
