Soybean meal and urea compositions have been found to exhibit enhanced and commercially useful nematistatic and nematicidal activity in soils. Chitin-containing materials, e.g., crab shells, shrimp shells, fungal mycella, etc., have also been found to exhibit enhanced and commercially useful nematistatic and nematicidal activity in soils when admixed with other organic nitrogen-containing materials such as ammonium phosphates, a source of urea, and plant, fish or animal meal. Also, compositions formulated of two different chitin source materials can be used. The soybean-urea compositions as well as the blended chitin-containing formulations are non-phytotoxic and simultaneously provide cost-effective biological suppression of plant pathogenic nematode populations and excellent plant nutrition.

Compositions for biological control of plant pathogenic nematodes

Preparation of high fructose syrups from citrus residues

A method for separating bacteriological growth inhibitors from sweet whey ultrafiltrate to form a mother liquor which is useful as a bacteriological culture media and a precipitate which is useful as a food grade additive to cause clouding, stabilization, emulsification, and thickening of food, pharmaceutical, and cosmetic compositions.

Culture media from clarified diary whey lactose permeates

A chitin-protein complex is prepared from chitin-containing biological waste material such as crustacean shells. The complex is different from both chitin and chitosan, and has useful nematostatic and nematocidal activity for agricultural and horticultural applications by admixing nematocidally effective amounts with a plant growth medium. The complex also provides a source of nitrogen in slow-release form, making it particularly suitable for combination with fertilizers, soil conditioners, etc.

Nematocidally active chitin-protein complex

The sugar content of citrus press liquor is enhanced by separating citrus solids, extracting fructose, glucose, and sucrose from the solids, and recombining the aqueous extract to increase the sugar content thereof. By inversion of the sucrose present in the sugar-enhanced press liquor, a high fructose syrup can be readily obtained which appears indistinguishable from high fructose corn syrup. When separation is effected by centrifugation, a colloidal phase is formed from which limonene and biocidal flavanoids can be extracted, resulting in a press liquor suitable for fermentation to alcohol. The solid residue remaining after extraction can also be recycled with the remaining press cake.
