    摘要： Protein concentrates are obtained in a process which includes: 1. Cultivating a hydrocarbon-consuming micro-organism in the presence of an aqueous nutrient medium, a hydrocarbon and a gas containing free oxygen; 2. CONTACTING THE CULTIVATED MICRO-ORGANISM FROM (1.) AT A TEMPERATURE BELOW THAT WHICH SUPPORTS ACTIVE FERMENTATION OF THE MICRO-ORGANISM WITH A GAS CONTAINING FREE OXYGEN IN THE PRESENCE OF AN AQUEOUS NUTRIENT MEDIUM CONTAINING A THIOSULFATE COMPOUND, E.G., SODIUM THIOSULFATE, AND A GAS CONTAINING FREE OXYGEN IN THE ABSENCE OF ADDED HYDROCARBON; AND 3. RECOVERING FROM (2.) A MICRO-ORGANISM HAVING (A) A PROTEIN CONTENT GREATER THAN THAT OF THE MICRO-ORGANISM OBTAINED IN (1.) AND (B) A SULFUR-CONTAINING AMINO ACID, E.G., CYSTINE AND METHIONINE, CONTENT GREATER THAN THAT OF THE MICRO-ORGANISM OBTAINED IN (1.).

    摘要： Wort is continuously supplied to a circuit including an elongated closed channel and through which micro-organisms are fed. After fermentation has taken place in the circuit, the mixture of wort and micro-organisms is centrifuged to separate it into fermented wort, a living cell mass and impurities, these three components being separately discharged from the centrifuge. The separate discharges of fermented wort and living cell mass are continuous, and the latter discharge includes an excess of living cells formed in the circuit, an amount of cell mass corresponding to this excess being discharged from the circuit.

    摘要： Alcohol or an alcoholic beverage is produced by a process wherein a mash of cereal grains and liquefying enzymes is cooked at a temperature of from 75.degree. C to 85.degree. C which is lower than the temperature of maximum viscosity for the mash and which is higher than the sterilization temperature of undesirable microorganisms in the mash which grow during fermentation with yeast. After cooking, the mash is cooled, saccharifying enzymes are added, the resultant mash is fermented with yeast to produce alcohol and the alcohol is distilled.

    摘要： IN THE CULTIVATION OF MICRO-ORGANISMS, A LIQUID HYDROCARBON FEEDSTOCK IS EMPLOYED CONTAINING AT LEAST 70% BY WEIGHT OF LINEAR PARAFFINIC HYDROCARBONS. THE GROWING STEP IS CONDUCTED IN THE PRESENCE OF A GAS-CONTAINING MOLECULAR OXYGEN AND WITH A NUTRIENT AQUEOUS MEDIUM CONTAINING; (A) ASSIMILABLE NITROGEN AND PHOSPHORUS; (B) OLIGOELEMENTS SUCH AS TRACE AMOUNTS OF COPPER, COBALT, IRON, MOLYBDENUM AND MANGANESE COMPOUNDS; (C) GROWTH FACTORS SUCH AS YEAST, ETC.; AND (D) ESSENTIAL MINERAL ELEMENTS SUCH AS POTASSIUM, AMMONIUM AND MAGNESIUM IONS. THE MICRO-ORGANISMS ARE THEN RECOVERED FROM AT LEAST THE MAJOR PART OF UNCONVERTED HYDROCARBONS, PREFERABLY BY DECANTATION, AND THEN SUBJECTED TO A MATURATION STEP IN AN AQUEOUS MEDIUM SIMILAR TO THE NUTRITIVE AQUEOUS MEDIUM, BUT DEPRIVED OF AT LEAST ONE OF THE ESSENTIAL MINERAL ELEMENTS.
