La présente invention concerne une nouvelle souche Bacillus firmus BC9 KCCM 10865P qui est hautement capable d'éliminer les mauvaises odeurs et les métaux lourds des eaux usées d'élevage et des rebuts alimentaires. Cette nouvelle souche peut s'utiliser seule ou en association avec d'autres espèces de Bacillus pour l'élimination des mauvaises odeurs et des métaux lourds. Elle peut également s'utiliser pour convertir en ressources utiles les eaux usées d'élevage ou les rebuts alimentaires.
