Abstract

Bacteria which utilized nitroaromatic compounds (0.5 mM) as sole source of nitrogen were isolated from soil. With 2,6-dinitrophenol and succinate as carbon source, a Pseudomonas strain was isolated which liberated and assimilated nitrite. Approximately 2 mol of NO(2) per mol of 2,6-dinitrophenol was released by resting cells. The xenobiotic compound was totally degraded, although specific growth yields were low even with succinate as a carbon source.

摘要

从土壤中分离到能够利用硝氮化合物(0.5mM)作为唯一氮源的细菌。以 2,6-二硝基苯酚和琥珀酸盐作为碳源,分离到一株能够释放和同化亚硝酸盐的假单胞菌。当以 2,6-二硝基苯酚作为唯一碳源时,静止细胞每摩尔 2,6-二硝基苯酚可释放约 2 摩尔的 NO(2)。尽管当以琥珀酸盐作为碳源时,特定生长产率较低,但这种外来化合物还是被完全降解了。
