LEGUMINOUS BACTERIUM HAVING POTENTIATED NITROGEN FIXATION ABILITY

摘要

A leguminous bacterium with potentiated nitrogen fixation which is a transformant bacterium transferred with a catalase gene to produce catalase, is new. Independent claims are also included for: (1) preparations for leguminous crops containing the leguminous bacteria as an active ingredient; and (2) growing leguminous crops by growing crop seeds having been brought into contact with the leguminous bacteria or preparations.
