Question

Largest bacteria- thiomargartia rambiensis

Answer 1

Thiomargarita namibiensis is a gram-negativecoccoid Proteobacterium, found in the ocean sediments of the continental shelf ofNamibia. It is the largest bacterium ever discovered, as a rule 0.1–0.3 mm (100–300 μm) in diameter, but sometimes attaining 0.75 mm (750 μm).[1][2] Cells of Thiomargarita namibiensis are large enough to be visible to the naked eye. Although the species holds the record for the most massive bacterium,Epulopiscium fishelsoni – previously discovered in the gut of surgeonfish – grows slightly longer, but narrower.
