Types of Bacteria According to Cell Wall Composition
Bacteria are classified into two main types depending on the results obtained when a sample of bacteria is tested by the Gram Stain Method.
Major Types of Bacteria: Actinobacteria
This phylum of thick-walled bacteria includes microorganisms that can be terrestrial as well as aquatic. Actinobacteria play a significant role in maintaining soil conditions and are, therefore, of huge importance in agriculture and forestry.
