CHEMOTAXONOMY IN BACTERIAL SYSTEMATICS

Özet

Öz In taxonomy, polyphasic approach is based on the principle of combining andevaluating different types of data obtained from microorganisms. While, during characterizationand identification of a microorganism, in the direction of polyphasic studies, chemotaxonomicanalysis has of paramount importance for the determination of the most important differencesbetween the family, genus and species comparatively. It is beyond doubt that, in recent yearssignificant developments have been achieved in systematics by the aid of molecular biologicalstudies. Phylogenetic data have revealed the hierarchical arrangement of the kinship relationsbetween the given bacteria, however, this information cannot provide reliable data on the level ofgenus. At this stage, chemical markers play an important role in regulating inter-taxarelationships. Chemotaxonomy; is the whole of the characterizations made by using thesimilarities 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 polymericcompounds to find the distribution of members of different taxa and all of this information isused for classification and identification. In this review, how the chemotaxonomic data can beused in bacterial systematics and reflected to application within the field questions wereevaluated.-REVIEW.
