Abstract

يتعلق الاختراع بسلالة العقدية الحرارية Streptococcus thermophilus strain موجبة اللاكتوز lactose-positive ، سالبة الجالاكتوز galactose-negative تطلق جلوكوز releasing glucose أثناء تخمير الحليب milk fermentation. تحمل سلالة العقدية الحرارية Streptococcus thermophilus strain هذه طفرة في الجين gene glcK، في الجين ccpA، في الجين gene lacZ و/أو في الجين ptsH، واختيارياً في واحد أو أكثر من الجينات genes ، تحديداً جين gene واحد، يشفر بروتين encoding a protein PTS خاص بمانوز- جلوكوز mannose-glucose-specific. يتعلق الاختراع أيضًا بتركيبة تشتمل على سلالة العقدية الحرارية Streptococcus thermophilus strain موجبة اللاكتوز lactose-positive ، سالبة الجالاكتوز galactose-negative واحدة على الأقل من الاختراع، واستخدام هذه السلالة أو التركيبة لتصنيع منتجات الألبان المخمرة fermented dairy product. شكل 2.
