Square

The bacteria are the most numerous type of cell found in salt lakes and are believed to be responsible for their characteristic red colour.

Square

Though the discovery was made decades ago, scientists found it extremely difficult to grow these bacteria in a lab to be able to study them. In 2004 they succeeded!

Stalked

Shape improves bacteria's ability to take up molecules from its environment.

Stalked

Bacterial strains of this shape can be engineered to efficiently take up toxins present at low concentrations in water sources and are being researched for bioremediation applications.
