 In the far future, the genetically engineered microorganisms could possibly be used to control the green house gases, convert the waste to the value-added product as well as to reduce and capture the carbon dioxide gases from the atmosphere (carbon sequestration), but lots of research still need to be done in order to make these potential become true.There is a concern regarding the use of genetically engineered microbes for the remediation of pollutants.Once the genetically microorganisms has been added, it may disperse uncontrollably and hard to be removed.
