An antibiotic producing Bacillus strain SR2, isolated from pea nut rhizosphere, showed in vitro antibiosis against many known plant pathogens. Seed bacterization with this strain showed an enhancement in seed germination, shoot height, root length, fresh and dry weights in four crop plants. A multiple drug resistant strain, SR2+, used to monitor root colonization confirmed the root colonization by the organism. Seed bacterization, reduced the number of chick pea wilted plants in wilt-sick soil, making the organism a potential bio-control agent against chick pea wilt.
从花生根际分离出的一株产抗生素芽孢杆菌菌株SR2，在体外对许多已知的植物病原体具有抗菌活性。用该菌株进行种子接种处理后，四种作物的种子发芽率、苗高、根长、鲜重和干重均有所提高。一株多重耐药菌株SR2 +被用于监测根部定殖情况，证实了该生物体能够在根部定殖。种子接种处理减少了萎蔫病土壤中鹰嘴豆萎蔫植株的数量，这使得该生物体成为防治鹰嘴豆枯萎病的潜在生物防治剂。
