摘要

The methanotrophic bacterium Methylococcus capsulatus (Bath) grows on pure methane. However, in a single cell protein production process using natural gas as methane source, a bacterial consortium is necessary to support growth over longer periods in continuous cultures. In different bioreactors of Norferm Danmark A/S, three bacteria consistently invaded M. capsulatus cultures growing under semi-sterile conditions in continuous culture. These bacteria have now been identified as a not yet described member of the Aneurinibacillus group, a Brevibacillus agri strain, and an acetate-oxidiser of the genus Ralstonia. The physiological roles of these bacteria in the bioreactor culture growing on natural, non-pure methane gas are discussed. The heterotrophic bacteria do not have the genetic capability to produce either the haemolytic enterotoxin complex HBL or non-haemolytic enterotoxin.
