In this article we will discuss about:- 1. Definitions of Taxonomy 2. Objectives of Taxonomy 3. Characteristics. Definitions of Taxonomy: Taxonomy is the science dealing with classification. In biology or in any other field, systematic classification is necessary to bring an order in the apparent chaos, so that the different types in a heterogeneous assemblage can be arranged into groups [...]
The following points highlight the three important types of bacteria. The types are: 1. The Ancient Bacteria 2. Gram-Positive Bacteria 3. Gram-Negative Bacteria. Type # 1. The Ancient Bacteria: Most of the phylogenetically primitive bacteria are thermophilic and Gram-negative (except Deinococcus). Some of them have ether-linked membrane lipids like those of archaebacteria. A few representative genera are briefly mentioned here. [...]
List of six special groups of bacteria:- 1. Anoxygenic Photosynthetic Bacteria 2. Oxygenic Photosynthetic Bacteria (Cyanobacteria) 3. The Methylotrophic Bacteria 4. The Nitrifying Bacteria 5. The Stalked and Prosthecate Bacteria 6. The Cyanomorphic Bacteria. Gram-Negative Bacteria: Group # 1. Anoxygenic Photosynthetic Bacteria: In the first edition of Bergey’s Manual of Systematic Bacteriology (1984), the anoxygenic photosynthetic bacteria were placed in [...]
