Abstract :

The aim of this study was to discover more about S. Macedonicus and its abilities by comparing it with a very well-known commercial bacterium like S. Thermophilus. As a member of the LAB, Streptococcus Thermophilus is identified as a thermophilic group and use as a commercial starter in industry. On the other hand, although Streptococcus Macedonicus was first described more than 16 years ago but still the exact role of this bacteria in the industry is not distinct. In this study, eight new isolated strains of S. Thermophilus and S. Macedonicus were applied to be compared with each other from the technological point of view. Analysis such as Growth in different PH, temperature and sugars, Antimicrobial susceptibility test and Inhibitory activity test were performed and the results were evaluated by using General linear model (GLM) in SAS 9.4. In all the comparison like growing in different PH, temperature and sugars between these two species, S. Macedonicus indicated the better growth rate which shows more functional bacteria. .
