Outline of Final Research Achievements

Phosphonates are organic phosphorus compounds containing C-P bond, and may be important phosphorus sources for marine microorganisms. It is also suggested that methylphosphonate, the simplest form of phosphonate, is a key compound in aerobic production of methane in the sea. In this study, the ability to utilize alkylphosphonates as phosphorus sources was demonstrated in some marine bacterial strains including methanotrophs by cultivation experiments. The genes related to phosphonate metabolism were found in genome sequences of two methanotrophic strains. Those genes are candidates for those encoding novel alkylphosphonate lyases.
