To select Lactobacillus acidophilus group bacteria as a probiotic yogurt starter, we designed a new screening method that measures the binding activity of surface layer protein to rat colonic mucin, w...
Production of Menaquinones by Lactic Acid Bacteria
menaquinones vitamin K2 lactic acid bacteria
2008/3/31
Lactic acid bacteria were examined for their ability to produce quinone compounds, which may include dietary sources of menaquinones. Isoprenyl quinones in bacterial cells grown in a synthetic medium ...
Study of the Possible Mechanisms Involved in the Mucosal Immune System Activation by Lactic Acid Bacteria
lactic acid bacteria intestinal interactions immunomodulation
2008/3/28
The induction of a mucosal immune response is not easy due to the development of oral tolerance, but under some conditions, bacteria can activate this immune system. Antigens administered orally can i...
Effect of High Pressure on the Viability and Enzymatic Activity of Mesophilic Lactic Acid Bacteria Isolated from Caprine Cheese
high pressure lactic acid bacteria enzymatic activity
