''Alkalihalobacillus alcalophilus'' (formerly ''Bacillus alcalophilus'') is a
Gram-positive,
rod-shaped
A bacillus (), also called a bacilliform bacterium or often just a rod (when the context makes the sense clear), is a rod-shaped bacterium or archaeon. Bacilli are found in many different taxonomic groups of bacteria. However, the name ''Bacillu ...
