چکیده مقاله:
Vitamin K۲ (menaquinone) is a form of vitamin K produced by bacteria. Dietary use of this vitamin is limited with soybean consumption food products. Products containing menaquinone help take advantage of its valuable health benefits. Cheese is a dairy product with the contents of menaquinone. Nine traditional Iranian cheeses were tested for the presence of menaquinone-producing bacteria by optical density at ۲۴۸nm and HPLC analysis since this vitamin content is thought to be linked to the cheese's bacterial makeup. Superior isolates characterization by ۱۶S rRNA analyzed them Lactococcus lactis subsp lactis CHT۸, and Leuconostoc mesenteroides CHG۱. Regarding the presence of these two bacteria in cheese production at different stages, including a starter or as probiotics, adding the feature of menaquinone production will offer a precious cheese.
