Özet

This study aimed to investigate the formation of tyramine during yoghurt fermentation with the focus on interaction between Streptococcus thermophilus RSKK 04082, Lactobacillus delbrueckii subsp. bulgaricus DSM 20081 and Lactobacillus plantarwn RSKK 02030. These microorganisms were used in the yoghurt fermentation as single strains or mixed cultures containing double or triple strains. The interactions between microorganisms have been also revealed by determining total free amino acids and the pH of the medium together with the microbial count of the strains. It was observed that L. delbrueckii subsp. bulgaricus DSM 20081 did not produce tyramine while S. thermophilus RSKK 04082 and L. plantar RSKK 02030 could produce tyramine depending on the fermentation conditions. Synergistic interactions between S. thermophilus RSKK 04082 and L. delbrueckii subsp. bulgaricus DSM 20081 and, between L. delbrueckii subsp. bulgaricus DSM 20081 and L. plantarum RSKK 02030 were found in terms of tyramine production. It was observed in this study that L. delbrueckii subsp. bulgaricus DSM 20081 had indirect effect on accumulation of tyramine in the yoghurts.
