BACTERIAL PHYLA Meaning and
Definition
-
Bacterial phyla refer to the major taxonomic groups or divisions into which the diverse range of bacteria is classified. Phyla, plural of phylum, are the highest taxonomic rank in the hierarchical classification system. In terms of bacteria, phyla signify the broadest classification level, beneath which there are various classes, orders, families, genera, and species.
Bacterial phyla encompass a multitude of different bacterial organisms, each sharing certain characteristics and genetic traits. They play a crucial role in understanding bacterial diversity and evolution. With advancements in DNA sequencing technologies, scientists have been able to identify and classify numerous bacterial phyla. As of now, over 100 bacterial phyla have been identified and named, with many more yet to be discovered.
Each bacterial phylum consists of groups of bacteria that share common features such as cell structure, metabolic pathways, reproductive mechanisms, and ecological roles. However, the specific characteristics and metabolic capabilities within each phylum can vary greatly.
Prominent examples of bacterial phyla include Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes, Cyanobacteria, and Spirochaetes. These phyla encompass a wide array of bacteria, ranging from common and well-known species like Escherichia coli and Bacillus subtilis to more obscure and unique microorganisms found in extreme environments such as hot springs or deep-sea vents.
Understanding bacterial phyla is vital for studying bacterial evolution, ecology, and their roles in various ecosystems. It enables scientists to explore the relationships between different bacterial groups, identify novel microbial species, and delve deeper into the mechanisms driving the diversity and adaptability of bacteria.
Etymology of BACTERIAL PHYLA
The word "bacterial" originates from the noun "bacteria", which comes from the Greek word "bakterion", meaning "little staff" or "rod". This term was coined by German physician Friedrich Anton Wilhelm M ü ller in 1828 when he observed microscopic rod-shaped organisms under the microscope.
The word "phyla" is the plural form of "phylum", which comes from the Greek word "phúlon", meaning "tribe" or "race". In biology, "phylum" refers to a taxonomic rank in the classification of living organisms, grouping together related organisms based on certain shared characteristics.
Therefore, "bacterial phyla" refers to the classification of different taxonomic groups or tribes within the bacteria kingdom.
