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
