What are the three main types of bacteria?
They are found everywhere and can be harmful, as in bacterial infections, or they can be beneficial, as in fermentation or decomposition. The three main bacteria shapes are coccus, bacillus and spiral. Keep reading for examples of bacteria in each of these three types.
Which is an example of a spiral shaped bacteria?
For example, diplococci are cocci in pairs, streptococci are chains, and staphylococci are clusters of multiple cocci. Tetrads are square arrangements of four cocci, while sarcinae are cubes of eight cocci. Spiral bacteria are, as the name suggests, spiral-shaped.
Which is an example of a Gram positive bacteria?
Examples of gram-positive bacteria include the genera Listeria, Streptococcus, and Bacillus, while gram-negative bacteria include Proteobacteria, green sulfur bacteria, and cyanobacteria. Escherichia coli is one example of a common species of bacteria.
Which is an example of a beneficial bacteria?
This beneficial bacterium is added in food supplements for use in therapeutic intervention. Nitrogen-Fixing Bacteria – Another group of useful bacteria is the nitrogen-fixing bacteria, which are crucial for plant growth. They help in assimilation of nitrogen from the atmosphere and soil, and covert it into usable compounds for plants.
