A catalase-like activity surrounding the root tips of rice plants favors the presence of Beggiatoa, an organism capable of oxidizing the hydrogen sulfide which is toxic to rice and is found in paddy soil conditions. Beggiatoa has now been isolated from rice field soil. A mutually favorable interaction between rice and this bacterium is suggested.
