Effect of Propionibacterium freudenreichii on Salmonella multiplication, motility, and association with avian epithelial cells

Lipase and Esterase Activities of Propionibacterium freudenreichii subsp. freudenreichii.

The lipase and esterase activities of eight strains of dairy Propionibacterium freudenreichii subsp. freudenreichii were studied. A lipase activity was detected on whole cells and in the culture supernatant. The highest activity was expressed at 45 degrees C and pH 6.8. An esterase activity was also detected in the culture medium. The electrophoresis of the intracellular fractions of the cells ...

Utilization of coenzyme A by Propionibacterium freudenreichii.

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...

Aminopeptidase activities of Propionibacterium freudenreichii dairy isolates

This study was undertaken to achieve more information on the aminopeptidase activities expressed in Propionibacterium freudenreichii strains naturally occurring in milk and dairy products. Fifty four strains belonging to both subspecies freudenreichii and shermanii were analyzed for activity towards different amino acyl β-naphthylamide (βNA) derivatives. The ability to efficiently hydrolyze ami...
