Other Research Directions Of Polycyclic Aromatic Hydrocarbon
Oct 20, 2017

research direction

The biodegradation of refractory organics in the environment, especially the biodegradation of Polycyclic Aromatic Hydrocarbon, is a matter of common interest to environmental scientists. Although microbial remediation is the most effective means of removing Polycyclic Aromatic Hydrocarbon, the technology is successfully applied to practice or subject to a variety of factors. The specificity of PAHs and their low water solubility limit their degradation by indigenous microorganisms. The following aspects are worthy of further study of the direction:

(1) To isolate high-molecular-weight polycyclic aromatic hydrocarbon (PAHs) with more than four rings as the only carbon source, to study the influencing factors of biodegradation and improve the biodegradability of existing bacteria.

(2) the microbial degradation pathway and mechanism of polycyclic aromatic hydrocarbon (PAHs), the intermediate process of degradation process and the structural properties of intermediates accumulated during the degradation process, and study the toxicity of certain degradation products.

⑶ through genetic engineering technology, the degradation of pollutants encoded by the plasmid or gene, into the environmental growth in the environment to survive the survival of indigenous microorganisms in the DNA, so that it has a strong ability to degrade pollutants, give full play to the role of bioremediation The

(4) The rhizosphere mechanism of microbial and plant remediation, phytoremediation of PAHs contaminated soil is in the initial stage, and microbial and plant remediation will be a promising new repair technology.

(5) In-depth study of the mechanism of biosurfactant production and its application in practical treatment, environmental factors on the impact of polycyclic aromatic hydrocarbon biodegradation and a series of actual pollution of soil and groundwater bioremediation related issues.
