Article Citation - WoS: 3Citation - Scopus: 2Bacterial Microbiota and Chemical Properties of Turkish Tarhana(Slovak Univ Agriculture Nitra, 2022) Omeroglu, Esra Ersoy; Can, Oezge; Temiz, Sevval Nur; Al, Rabia; Altunbas, Osman; Soyucok, Ali; Sudagidan, MertTarhana is one of the traditional Turkish fermented food and it is served as a soup. In this study, bacterial microbiota and chemical properties (acidity, salt, and moisture content) of tarhana samples (n=96) were examined. The metagenomic analysis revealed that Firmicutes were the dominant phylum and Bacillaceae, Enterococcaceae, Paenibacillaceae, Enterobacteriaceae, and Clostridiaceae were the dominant bacterial families. In the samples, Bacillus, Enterococcus, and Paenibacillus were mostly identified at the genus level. Alpha diversity and evenness showed that sample 30 had the highest diversity collected from Izmir. Principal Coordinate Analysis was used to identify relationships of samples at different taxonomic levels and it was found that most of the samples were closely related at the phylum level. Chemical analysis indicated that the acidity of tarhana samples varied between 5.00% and 42.5%, moisture contents were 4.39- 18.66% and salt values were from 0.32% to 6.64%. The results of this study extensively demonstrated the chemical properties and the dominant bacterial communities present in tarhana samples collected from different parts of Turkiye.Article Citation - WoS: 4Citation - Scopus: 6Bacterial and Fungal Microbiota of Mould-Ripened Cheese Produced in Konya(Wiley, 2023) Yurt, Mediha Nur Zafer; Omeroglu, Esra Ersoy; Tasbasi, Behiye Busra; Acar, Elif Esma; Altunbas, Osman; Ozalp, Veli Cengiz; Sudagidan, MertBacterial and fungal diversities of 24 mould-ripened cheeses originating from Konya-Turkiye were examined by metagenomic analysis. Firmicutes phylum, Enterococcus, Clostridium sensu stricto and Lactobacillus (Levilactobacillus) genera were the dominant bacteria. Ascomycota phylum and Penicillium and Pichia genera and Penicillium roqueforti and Pichia membranifaciens species were dominant fungi. Enterococcus faecium (n = 30) and Enterococcus faecalis (n = 6) were identified, and all strains were susceptible to penicillin, ampicillin, vancomycin, teicoplanin, chloramphenicol and linezolid. The highest resistance (n = 14) was against rifampin. Tetracycline resistance was determined in two strains. Biofilm-forming ability was found in nine E. faecium and 1 E. faecalis. E. faecium strains revealed 40-88.9%, and E. faecalis showed 59.2-100% homology by pulsed field gel electrophoresis.
