A storage stable frozen lactic acid bacteria (LAB) culture that comprises LAB that are that are able to utilize sucrose, has a weight of at least 50 g frozen material and a content of viable bacteria of at least 10.sup.9 colony forming units (CFU) per g frozen material.

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 invention relates to a method for producing a fermented dairy product, comprising: (a) providing a milk substrate, (b) fermenting said milk substrate with a lactic acid bacterium starter culture, wherein step (b) is conducted in the presence of at least one Bacillus strain selected from the group consisting of a sporulation-negative Bacillus subtilis subsp. natto strain, a sporulation-negative Bacillus coagulans strain, wherein a sporulation-negative strain is a strain, which forms no spores when subjected to the following method: i) inoculating 1% of a culture of the strain to be tested, grown over night in Veal Infusion Broth (VIB) at 37° C., 180 rpm, into 50 ml of a standard sporulation inducing medium contained in a 500 ml baffled shake flask, ii) allowing the inoculated medium to grow overnight at 37° C. while subjecting it to shaking at 0rpm, and iii) testing for spores the next day.

A production method for an edible fermented dairy product using, as a raw material, sterile full fat soy flour and a fermented dairy product produced by the method. A production method for a fermented dairy product includes the steps of: producing sterile full fat soy flour having a grain size of from 100 to 1,000 meshes by pulverizing sterile dehulled soybeans prepared so as to have a bacterial count of 300 cells/g or less by using a method of separating whole soybeans into cotyledons, germs, and hulls; adding water to the sterile full fat soy flour to prepare a powdered soy juice, followed by sterilizing the powdered soy juice by heating; homogenizing the powdered soy juice to prepare a homogenized powdered soy juice; and adding a lactic acid bacterium to the homogenized powdered soy juice, followed by fermentation to prepare fermented milk.

A low-mineral quark matrix is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to an ultrafiltration step and/or a reverse osmosis step, producing a retentate R1, which represents a dairy protein concentrate, and a permeate P1, (c) subjecting the permeate P1 to an electrodialysis step, producing a salt-depleted diluate D1, (d) combining the diluate D1 with the retentate R1, (e) subjecting the combination product such obtained to heat treatment until denaturation sets in, (f) fermenting the denaturation product such obtained by the addition of starter cultures and rennet, and (g) adjusting or standardising the fermentation product such obtained to defined dry matter and protein contents.

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.
