On the environmental pollutants disposal producing from volatile petroleum based on micro-biological degradation

Abstract

All the strains screened out from contaminated soils we re capable of degrading diesel oil while consortium and strains Q18 had stronger degradation efficiency. It’s found that the existence of alfalfa and mustard could promote the degradation of diesel oil significantly. The existence of plant and the growth of roots may have changed the soil environment to make it more suitable for the growth of strains and degradation. In addition, the number of strains in the mustard rhizosphere was larger than that in the alfa lfa rhizosphere, which showed that mustard had stronger ability on the activation of strain. This may be related to the different growth characteristics of mustard and alfalfa. In the experiment, Rhodococcus Q18-Indian mustard complex had the highest rate of degradation of diesel oil.
