土壤浆料中 13 种氯芳烃、2-氯-、3-氯-、4-氯-和 3,4-二氯苯胺、2-氯-、3-氯-、4-氯-、3,4-二氯-和 3,5-二氯苯甲酸酯以及氯-、1,2-二氯-、1,4-二氯-和 1,2,4-三氯苯的混合物的降解对食酸假单胞菌BN 3.1、鲁兰假单胞菌FRB2、洋葱假单胞菌JH230和铜绿假单胞菌RHO1的混合培养进行了研究。当将每个菌株的 2-3 × 105 个细胞/克土壤添加到浆料中时，25 天后，碳含量为 8% 的土壤（土壤 1）中约 70% 的有机结合氯被消除。使用水芹和小麦进行的生物测试证明了清理的效果。在用菌株进行生物处理后，两种植物在未受污染的土壤和受污染的土壤1上均表现出良好的发芽和生长。当植物与受污染的土壤 1 和受污染且生物处理的土壤 2（碳含量 2.6%）一起培养时，没有观察到生长。这表明生物处理后土壤1中剩余的30%有机氯并没有影响受试两种植物的发芽和生长。 *** 直接支持 *** AG903062 00010
The degradation of a mixture of 13 chloroaromatics, 2-chloro-, 3-chloro-, 4-chloro- and 3,4-dichloroaniline,2-chloro-, 3-chloro-,4-chloro-, 3,4-dichloro-and 3,5-dichlorobenzoate, and chloro-,1,2-dichloro-, 1,4-dichloro- and 1,2,4-trichlorobenzene in soil slurries by a mixed culture ofPseudomonas acidovoransstrain BN 3.1,Pseudomonas ruhlandiistrain FRB2,Pseudomonas cepaciastrain JH230 andPseudomonas aeruginosastrain RHO1 was studied. About 70% of the organic bound chlorine was eliminated after 25 days from soil with a carbon content of 8% (soil 1) when 2–3 × 105cells/g soil of each of the strains were added to the slurries. The effect of the clean-up was demonstrated by a biological test using cress and wheat. Both plants showed good germination and growth on both non-contaminated soils and the contaminated soil 1 after the biotreatment with the strains. No growth was observed when the plants were incubated with the contaminated soil 1 and with the contaminated and biotreated soil 2 (carbon content 2.6%). This indicates that the remaining 30% of organic chlorine in soil 1 after biotreatment does not influence the germination and growth of the two plants tested. *** DIRECT SUPPORT *** AG903062 00010
