假单胞菌和P的最低抑制浓度均检测到Cd2+ 。SN4的铜绿菌对镉的耐受性最高,可达1800μg/ml。大部分分离菌株表现出多金属和多种抗生素的耐受性。在盆栽试验研究中,P。在Cd土壤(50 mg/kg)中, SN4的铜绿假单胞菌茎长显著增加。苗期20 d后,在土壤中接种Cd,施用P。与未接种的对照盆栽相比,绿脓杆菌SN4,水稻植株的幼苗生长和萌发率提高了12%。总体研究表明P。 aeruginosa SN4 could increase the growth of Oryza sativa in cadmium incorporated soil, thus dedicating the sites which are set aside for long term agricultural purpose.
