    Chemotaxonomy ın bacterıal systematıcs
    (Ankara Üniversitesi Fen Fakültesi, 2019) Aras, Emine Sümer; Biyoloji; Fen Fakültesi
    In taxonomy, polyphasic approach is based on the principle of combining and evaluating different types of data obtained from microorganisms. While, during characterization and identification of a microorganism, in the direction of polyphasic studies, chemotaxonomic analysis has of paramount importance for the determination of the most important differences between the family, genus and species comparatively. It is beyond doubt that, in recent years significant developments have been achieved in systematics by the aid of molecular biological studies. Phylogenetic data have revealed the hierarchical arrangement of the kinship relations between the given bacteria, however, this information cannot provide reliable data on the level of genus. At this stage, chemical markers play an important role in regulating inter-taxa relationships. Chemotaxonomy; is the whole of the characterizations made by using the similarities and differences of the biochemical properties of bacteria. In bacterial systematics, chemotaxonomy examines biochemical markers such as: amino acids and peptides (peptidoglycan), lipids (fatty acid, lipopolysaccharides, micolic acid and polar lipids), polysaccharides and related polymers (teicoic acid, whole sugar) and other complex polymeric compounds to find the distribution of members of different taxa and all of this information is used for classification and identification. In this review, how the chemotaxonomic data can be used in bacterial systematics and reflected to application within the field questions were evaluated.-REVIEW.
