Bioremediation of Crude-Oil Polluted Soil Using Immobilized Microbes

Abstract Microbial bioremediation technologies in the past usually cannot degrade the corrosive pollutants in the polluted soil. These microbial bioremediation technologies are often impacted by many environmental factors, and therefore the remediation effect of these bioremediation technologies on the polluted soil is reduced. With the advance of science and technology, more advanced immobilized microbial remediation technologies are developed. These technologies have been growing rapidly due to their advantages over the old microbial remediation technologies. This paper investigates and researches the immobilized microbial and other remediation technologies, and the results show in the process of remediation of polluted soil using immobilized microbes, that the activity characterization of enzyme and the number of bacteria are both relatively higher. Moreover, this paper provides the detailed statistics on various factors that impact the effect in remediating oil polluted soil using immobilized microbial remediation.
