Bacillus pseudofirmus

Bacillus pseudofirmus is a facultative anaerobe bacterium. It is a gram positive, alkaliphilic and alkalitolerant, aerobic endospore-forming bacteria.

In 2019, it was found in a hyperalkaline spring in Zambales (Philippines) a bacterial consortium of a strain of Bacillus pseudofirmus with Bacillus agaradhaerens that can biodegrade LDPE plastic.

This species has been recently transferred into the genus Alkalihalobacillus. The correct nomenclature is Alkalihalobacillus pseudofirmus.
