Method of proliferating a microorganism capable of degrading a hard-to-degrade organic compound and method of degrading a hard-to-degrade arganic compound

摘要

The present invention provides a method of proliferating a microorganism capable of degrading a hard-to-degrade organic compound, comprising proliferating at least one microorganism capable of degrading a hard-to-degrade organic compound selected from the group consisting of Janibacter genus, Pseudomonas genus, Rhodococcus genus, Desulfomonile genus, Alcaligenes genus, Bacillus genus, Streptococcus genus, Acinetobacter genus, Achromobacter genus, Paracoccus genus, Rhodobacter genus, Rhodobacterium genus, Methylosinus genus, Mycobacterium genus, Nitrosomonas genus, Corynebacterium genus, and Methanotrophs, in a culture medium containing both a substance capable of inducing the degradation capability of the microorganism and Fe ions, under inorganic conditions. The present invention also provides a method of degrading a hard-to-degrade organic compound by using a microorganism capable of degrading the hard-to-degrade organic compound, comprising a step of controlling the degradation capability of the microorganism by adjusting the concentration of Fe ions in the culture medium.
