Leave a Comment / Uncategorized / Uncategorized Recent advances in biochemical and electron microscopic techniques, as well as in testing that investigates the genetic relatedness among species, have redefined previously established taxonomic relationships and have fortified support for a five-kingdom classification of living organisms. Bacteria obtain nutrition in different forms. ♦ Autotrophs: These are bacteria which prepare their own food. Because of this variety, bacteria may be grouped using many different typing schemes. The Taxonomic Hierarchy. Check out:→ Use of Bacteria to humans and the environment. classification: the act of forming into a class or classes; a distribution into groups, as classes, orders, families, etc., according to some common relations or attributes. The current classification of Bacteria and Archaea is based on an operational-based model, the so-called polyphasic approach, comprised of phenotypic, chemotaxonomic and genotypic data, as well as phylogenetic information. A few different criteria are used to classify bacteria. Mycology can simply be defined as the study of fungi. Describe the different types of bacteria 3.
