Disclosed is a method of efficiently aerating yeast prior to pitching. In the method, yeast are aerated in an aqueous sugar solution containing zinc.

Disclosed is a an economical method of efficiently oxygenating yeast slurry without bubble formation. The method employs a membrane oxygenator comprising at least one hydrophobic, microporous membrane having a gas side and a liquid side. The yeast slurry flows over the liquid side of the membrane; oxygen is delivered to the gas side of the membrane and passes through the pores to the yeast slurry.

Diapers and wet wipes for cleansing of infants are made anti-bacterial by the inclusion therein of hop acid derivatives, specifically tetrahydroiso-alpha acid and hexahydro-beta acid. These compounds are effective to inhibit the growth of gram-positive bacteria, and specifically chosen to combat, a primary factor in toxic shock syndrome in infants.

Antimicrobial diapers and wet wipes

The present invention provides methods, products, and compositions for selectively inhibiting the growth ofwithout preventing the growth ofspecies. Specifically, the present invention discloses the use of tetrahydroiso alpha acid or hexahydro beta acid at a concentration effective to inhibit the growth ofwithout preventing the growth of. The inhibition ofin accordance with the present invention thus provides useful methods, compositions and products such as feminine hygiene products for treating the diseases associated withinfections and infestations, i.e., toxic shock syndrome, without disrupting the normal bacterial flora in the area of its application.

An improved method for reducing colony forming units bacteria in yeast is disclosed. The method involves contacting the yeast with a hop acid in an amount sufficient to give a final concentration of the hop acid of at least about 40 ppm.

Method for decontaminating yeast

Yeast is genetically engineered by transformation with an expression vector containing a natural yeast secretion signal sequence combined appropriately with a chemically synthesized gene encoding antifreeze protein resulting in the expression, proper processing, and secretion of antifreeze protein which is heterologous to yeast in recoverable amounts. Disclosed are DNA sequences comprising structural genes encoding peptides having amino acid sequences with the biochemical or physiochemical properties of antifreeze protein and a method of combining the antifreeze protein gene sequences with appropriate expression vectors.

Method of expressing antifreeze proteins in yeast

A method of inhibiting Listeria in a medium comprises adding to the medium an effective amount of tetrahydroisohumulone or hexahydrocolupulone or mixtures or salts thereof to inhibit any Listeria.

Method of inhibiting listeria

Oral care compositions containing hop acids or their salts are effective in inhibiting Gram positive bacteria which can cause plaque or periodontal disease. A representative composition is a toothpaste containing tetrahydroisohumulone.

Oral care compositions containing hop acids and method

Beer spoilage microorganisms are detected with a culture medium that is advantageous for detecting Lactobacillus spp., Pediococcus spp. and wild yeast, and which allows detection to be carried out in four days. The medium contains tomato juice, peptones, cysteine hydrochloride, sorbitan nonooleate, mono and disaccharides, yeast extract, beef extract, potassium acetate, malic acid, mono and dibasic potassium phosphate, magnesium sulfate, maganese sulfate, sodium chloride, ferrous sulfate, beer, water and agar.
