    Biosynthesis of folates by lactic acid bacteria and Propionibacteria in fermented milk

  • Original language description

    Folate producing ability of several strains of Bifidobacterium longum, Bifidobacterium bifidum, Streptococcus thermophilus and Propionibacterium freudenreichii subsp. shermanii was evaluated. UHT milk with 1.5 % fat content treated by additional laboratory sterilisation represented the substrate. Fermentation was conducted at 37°C and 30°C in case of Propionibacterium. 5-methyltetrahydrofolate (5-MTHF) concentrations were determined using HPLC method. All tested strains of Streptococcus thermophilus showed 5-MTHF production. More than six-fold increase was found in 5-MTHF content in comparison with control (increase = 3.69 ug 5-MTHF/100g) after 12 hrs fermentation. Bifidobacterium longum strains were recognized as a mild folate producers with max 73% increase in 5-MTHF content (increase = 0.48 ug 5-MTHF/100g) after 12hrs fermentation. Tested Propionibacterium freudenreichii subsp. shermanii strains did not basically influence the 5-MTHF level during milk fermentation. In all cases maxi

    Biosyntéza folátů ve fermentovaném mléce pomocí bakterií mléčného kvašení a Propionibaceria

  • Czech description

    Byla hodnocena schopnost produkce folátů několika kmenů Bifidobacterium longum, Bifidobacterium bifidum, Streptococcus thermophilus and Propionibacterium freudenreichii subsp. Shermanii. Jako substrát bylo použito UHT mléko o obsahu tuku 1,5% ošetřené dodatečnou labotatorní sterilací. Fermentace byla prováděna při 37°C, v případě Propionibacterium při 30°C. Koncentrace 5-methyltetrahydrofolátu (5-MTHF) byla stanovena metodou HPLC. Všechny testované kmeny Streptococcus thermophilus vykázaly produkci 5-MTHF. Po 12 hod fermentace byl nalezen více než šestinásobný nárůst obsahu ve srovnání s kontrolou (nárůst = 3,69 ug/100g). Bifidobacterium longum lze řadit mezi mírné producenty s max. nárůstem koncentrace 5-MTHF 73% (nárůst = 0,48ug/100g) po 12 hod fermentace. Testované kmeny Propionibacterium freudenreichii subsp. Shermanii během fermentace hladiny folátů prakticky neovlivnily. Ve všech případech bylo maximum koncentrace 5-MTHF nalezeno mezi 6 a 12 h fermentace. Produkce jednotlivých km
