Full textS. thermophilus and L. delbrueckii subsp. bulgaricus. In this study, identification and typing of yoghurt starter bacteria were aimed. Traditional home made yoghurts were collected from different areas of Turkey, identification of those isolates at species and subspecies level and typing at strain level were achieved using PCR based methods. In our study, identification of yogurt starter bacteria was studied using species specific primers and ARDRA. These methods were inefficient in identification of yoghurt starter bacteria, at species and subspecies level. Consequently, a reliable and quick method for accurate identification of yoghurt starter bacteria was developed. The new method focuses on amplification of methionine biosynthesis genes, for selective identification of yoghurt starter bacteria together with some cheese starters. Further discrimination by ARDRA enabled differentiation of yoghurt starter bacteria from cheese starters. Confirmation of the proposed method has been accomplished by partial sequencing of the 16S rRNA gene. After correct identification of starter bacteria had been achieved, the strains were typed at strain level using RAPD-PCR and MLST. RAPD-PCR with primer 1254 resulted better fingerprints, compared to primer M13 at strain level. Comparisons of the two typing methods showed that RAPD-PCR revealed strain diversity better than MLST, however MLST was a more robust and reliable method and resulted in clustering of the strains depending on the isolation source.

Full textCryopreservation leads to variable degradation of the biological activity and functionality among lactic acid bacteria (LAB), particularly Lactobacillus delbrueckii subsp. bulgaricus, a dairy starter of industrial relevance. The aim of this work was to identify cellular markers of cryoresistance or cryosensitivity for better understanding the mechanisms of cell cryoinjury and increasing LAB industrial performances. Cryopreservation was here considered as a combination of cold and osmotic stresses. A particular focus was given to the analysis of the cell membrane, recognised as a primary site of cryoinjury, but also of the cell wall and proteins. Moreover, cells were analysed from the population level down to the single-cell level to quantify the heterogeneity of cell properties within populations. In the first part of this work, bacterial cultivation conditions were compared to identify two L. bulgaricus strains with markedly different cell cryoresistance. Moreover, a comparative genomic analysis of the strains was performed to provide some clues for the explanation of their different behaviours. In the second part of this work, the membrane properties were evaluated in response to the cold and osmotic stresses: fatty acid composition, organisation of fatty acyl and phospholipid headgroups, and fluidity.Subcellular membrane fluidity was also characterised by fluorescence microscopy using synchrotron radiation, enabling the quantification of inter- and intra-cellular heterogeneities. Finally, original methodological and technical developments were undertaken to achieve the analysis of individual bacterial cells in an aqueous environment by Fourier transform infrared (FTIR) spectroscopy, for the analysis of the biochemical signature of cells under native conditions. These complementary multidisciplinary approaches revealed different properties and organisation of the membrane of both L. bulgaricus strains. It was proposed that different types of interaction between cryoprotectants of the extracellular matrix and the membrane of both strains could be at the origin of cryoinjury for the sensitive strain. Moreover, a high population heterogeneity characterised the cryosensitive strain, ascribed to differences in terms of biochemical composition and organisation of the membrane and cell wall. Altogether, this work suggests some cellular markers to evaluate LAB cryoresistance and provides methods to characterize population biochemical heterogeneity. These could be applied to any other stressful step of their production process, and should be useful for future production of homogeneous populations of resistant LAB
