Abstract
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.
