Samsung patents bioreactor using bacteria to clean nitrogen oxide
Samsung has been granted a patent for a method that uses microorganisms to lower the concentration of nitrogen oxides in a sample. The process involves a specific type of reactor called a plug flow reactor, where bacteria interact with a chemical complex containing iron and nitrogen oxide to break down the pollutants.
In the filing’s own words
A method of reducing a concentration of a nitrogen oxide, the method comprising: contacting a microorganism with a nitrogen oxide-containing sample to reduce the concentration of the nitrogen oxide in the sample, wherein the contacting comprises contacting the microorganism with Fe(II)(L)-NO x in a bioreactor, wherein the Fe(II)(L)-NO x is a complex in which a chelating agent, Fe 2+, and NO x are chelated, wherein L is the chelating agent, and wherein NO x is a nitrogen oxide ligand.
What exactly they claim (claim 1)
1. A method of reducing a concentration of a nitrogen oxide, the method comprising: contacting a microorganism with a nitrogen oxide-containing sample to reduce the concentration of the nitrogen oxide in the sample, wherein the contacting comprises contacting the microorganism with Fe(II)(L)-NO x in a bioreactor, wherein the bioreactor is a plug flow reactor comprising a plurality of carriers, wherein the Fe(II)(L)-NO x is a complex in which a chelating agent, Fe 2+, and NO x are chelated, wherein L is the chelating agent, and wherein NO x is a nitrogen oxide ligand.
