The present invention relates to the field of microbiology, specifically the field of production of a dairy food product using fermentation and the field of gene transfer by conjugation.

The present invention relates to a method for producing a cheese-flavored substance, including adding a bacterial cell disrupted product obtained by disrupting lactic acid bacteria and an enzyme to a milk raw material to cause a reaction. The present invention can provide a method for producing a cheese-flavored substance which can safely and efficiently produce a cheese-flavored substance having a more natural cheese flavor at low-cost with simple operation.

An object of the present invention is to provide a method for efficiently obtaining a lactic bacterium having a high double-stranded RNA content obtained by the method. The object is achieved by: (1) a method for producing a double-stranded RNA-containing lactic acid bacterium, including a step of culturing a lactic acid bacterium under at least one condition of an aeration condition and a low-temperature condition lower than an optimum temperature, thereby obtaining the double-stranded RNA-containing lactic acid bacterium; (2) a double-stranded RNA-containing lactic acid bacterium, in which the content of double-stranded RNA is 2.0 times or more as compared with the content of double stranded RNA when a bacterium of the same strain is cultured for the same culture time under an optimum temperature and non-aeration condition; or the like.

The present invention is a yogurt product that may be consumed by dogs and other mammalian pets. The yogurt product is in an unflavored form comprising as essential constituents: (A) 0% to 88% by weight water; (B) 0.2% to 25% by weight of a no-fat protein component selected from the group consisting of skim milk and cultured skim milk; (C1) 0.001% to 6% by weight sugar component comprising: (C1) 0.001% to 6% polydextrose and (C2) 0.001% to 6% Glycoses and Galactoses; (D) 2% to 8% by weight milk derived solids; (E) 0.2% to 2.5% by weight stabilizers and emulsifiers; and (F) at least one probiotic microorganism. The yogurt product may be refrigerated and served as a mousse, frozen dessert, or as a fermented yogurt drink similar to Ayran or Kefir. A method for producing the yogurt product is also disclosed herein.

The present invention relates to the field of microbiology, specifically the field of production of a dairy food product using fermentation and the field of gene transfer by conjugation.

A nutritional composition obtainable by fermenting a mixture comprising protein, carbohydrate and fat, wherein the major source of protein is potato protein, and wherein the mixture is fermented by lactic acid-producing bacteria.

A method for producing a cheese with reduced amount of galactose comprising inoculating milk with Streptococcus thermophilus Gal(+) bacteria and Lactobacillus Gal(+) Lac(?) bacteria.

The present invention is directed to a method for decreasing the lag time in a fermentation of a culture medium to prepare a target substance, wherein the target substance is not yogurt and wherein the fermentation results in formation of acid or ethanol, which method comprises the steps of providing, to a suitable culture medium, a fermentation starter culture comprising a microorganism which liberates acid or ethanol, adding a potato protein protease inhibitor to the culture medium, culturing the microorganism, and obtaining the target substance.

It has been found that addition of potato protein protease inhibitor to a fermentation feed significantly reduces the lag time of the fermentation. The required amount of potato protein is low enough not to affect the taste of the target substance adversely, and the lag time reduction occurs both in batch- and in semi-continuous processes. The invention further pertains to a fermented food product which is not yogurt, comprising potato protein protease inhibitor.
