In the previous article, similar gene sequences of an established mercuric ion reductase or merA gene were identified. They were studied from the NCBI database using BLAST tool. In this article, the protein sequence of merA enzyme is studied with respect to its closely related sequences found in NCBI database, through Multiple Sequence Alignment (MSA).
Phytoremediation is a method which involves growing plants in a contaminated matrix to remove environmental contaminants.It is the direct use of living green plants for the removal and degradation of contaminants in the soil as well as water bodies (Hassani et al. 2014).
Naturally occurring organisms possess genes with remediating properties. However, using genetic engineering techniques is advantageous to transfer these genes to other organisms (Joutey et al., 2013). Such techniques help increase the bioremediation efficiency.
Microbial remediation has shown significant potential in mitigating a wide range of pollutants, in a much more efficient and safe manner. While reviewing literature on pollutants, 6 main classes were determined, depending upon their chemical nature or constituents or sources.
