Abstract

Microorganisms that use the flotation agent T-66 as the sole source of carbon have been isolated from soil enriched with this agent. A mixture of bacterial cultures belonging to the genus Pseudomonas (Ps. fluorescens, Ps. desmolyticum, Ps. rathonis, Ps. cyanoides viscosa, and Ps. aeruginosa) oxidized, after adaptation, at a high rate, components of the flotation agent T-66. Aeration of the medium accelerated the destruction. About 90% of the foltation agent components were oxidized within four months. The highest activity was observed during the first two months. The bacteria also decomposed, actively, oxidized kerosene and oxidized recycle stock added as the sole source of carbon to a mineral medium. Introduction of glucose to the medium accelerated destruction of oxidized recycle stock by the microorganisms, but inhibited destruction of oxidized kerosene.

摘要

已从富含浮选剂T - 66的土壤中分离出以该浮选剂作为唯一碳源的微生物。一组属于假单胞菌属(荧光假单胞菌、解朊假单胞菌、拉氏假单胞菌、粘性蓝假单胞菌和铜绿假单胞菌)的混合细菌培养物在适应后能高速氧化浮选剂T - 66的成分。培养基通气加速了这种破坏。约90%的浮选剂成分在四个月内被氧化。在前两个月观察到最高活性。这些细菌还能积极分解氧化煤油以及作为唯一碳源添加到矿物培养基中的氧化循环物料。向培养基中添加葡萄糖加速了微生物对氧化循环物料的破坏,但抑制了氧化煤油的破坏。
