Bacillus mycoides

From Biology-Online Dictionary | Biology-Online Dictionary



A gram-positive non motile spore formers soil bacterium that typically has a characteristic of spreading filamentary morphology regarded as saprophytic organisms which is ecologically distinct from its pathogenic close relatives.


Bacillus mycoides has a size larger than 3 micrometers that form chains and acid from glucose which is non-motile found generally in soil used as pesticide to inhibit the growth of harmful bacteria and fungi. It has no harmful effects on environment as well as in humans. It has a distinctive characteristic of fatty acid profile and acetanilide-producing activities.

Bacillus mycoides acts as an ammonifying bacterium where it is capable to convert ammonia into ammonium needed for nitrifying bacteria to form nitrite, a useful compound and beneficial in the soil leading to the edge of nitrogen cycle in an ecosystem.

Bacillus mycoides is small spherical bodies, gonidia and yeast-like cocci that is able to reproduce without changing the form known as cyclogeny or symplastic method of reproduction. Its growth in media responded to the force by growing in a direction parallel to the extension strain and perpendicular to the compression strain wherein the filaments are vertically aligned in the center, thus exhibits different filament orientations due to varying direction of forces.
