Abstract: The quality of coating in autodeposition from solutions in which the coating is predominantly derived from epoxy resins can be improved in two ways, which can be used jointly or separately: A blocked isocyanate is used as cross linking agent for the epoxy resin, and a surfactant that prevents the occurrence of phase separation during drying of the coating is used. Preferably the surfactant is a fluoroaliphatic polymer ester.

Abstract: In a process for polymerizing monomers with free-radical initiators in aqueous solution to produce polymers useful in oil field applications, wherein said polymerization process employs an oxygen-scavenging agent, the improvement which comprises employing said oxygen scavenging agent and oxidase enzyme with a substrate therefor, optionally with a catalase, such as alcohol oxidase and methanol, to consume dissolved oxygen in a polymerization admixture. Oxygen-scavenging under field conditions with the oxidase/substrate system permits consistent production conveniently of water based polymer solutions of good viscosity for oil field applications.

Abstract: A process for the production of microbial cells by fermentation of carbonaceous material in a foam fermenter containing an oxygen-enriched nutrient medium. The process uses a source of carbon which is assimilable by the microorganism for the produciton of the microbial cells. The microbial cells are separated and removed from the foam fermenter for use as a food product high in protein content. The process includes the controlled release of a quantity of the constituents of a portion of the microorganism within the fermenter to increase the maintenance of the source of carbon and the nutrient medium in a foamed condition at a predetermined level in the fermenter. Also dislosed are various forms of apparatus for practicing the process of the present invention.

Abstract: A process to recover proteins, such as enzymes, from yeast cells, which comprises forming an admixture of yeast cells, water, and a minor effective amount of a polychloro aliphatic hydrocarbon, at a suitable pH, and incubating for a suitable time and temperature, such as at room temperature, of about 16 to 90 hours. The resulting supernatant is separated as an aqueous liquid containing a high enzyme activity. Enzymes can be recovered, if desired. Typical applications include Kluyveromyces fragilis for lactase, Pichia pastoris for alcohol oxidase. Typical solvents include methylene dichloride, 1,1,1-trichloroethane, and chloroform.

Abstract: A new alcohol oxidase is isolated from Pichia-type microorganisms in soluble or crystalline form. The crystalline novel enzyme is isolated by preparing an aqueous fluid containing cells of a Pichia-type microorganism, homogenizing the fluid and separating solids therefrom to produce an alcohol oxidase solution, adjusting the solution to have an ionic strength in the range of 0.05 to 0.01 in ionic strength to form a recovery range solution thereby causing the crystalline alcohol oxidase to form. The new enzyme is used to determine alcohol concentrations in fluid samples in which conditions are compatible with the enzyme's activity.

C. to 40.degree. C. for about 2 minutes to 2 hours at a pH of about 8 to 11. The yeast cells are preferably Pichia pastoris and the alkaline protease is preferably from Bacillus lichenformis.

Abstract: The concentration of a C.sub.1 to C.sub.4 alcohol in an essentially water immiscible organic system is accurately determined by a simple and quick process. A sample of the water immiscible organic system containing less than about 0.01% (W/V) of the alcohol is contacted with an aqueous layer of alcohol oxidase immobilized on an electrode for measuring dissolved oxygen content. Ethanol in the water immiscible organic system partitions into the aqueous layer where alcohol oxidase catalyzes oxidation of the alcohol. Oxygen consumed during the oxidation is measured by the electrode, and the concentration of alcohol determined therefrom. To obtain less than about 0.01% alcohol in the sample, the sample may be diluted with the water immiscible organic system.
