The alternatives for bioconversion of monoethanolamine(MEA), which would appear in large quantities in industrial effluent of CO2-removal process of power companies, have been proposed by investigating the ability of some microoganisms to deaminate MEA. An evaluation of biotechnology, which include productions from MEA of acetic acid and acetaldehyde with Escherichia coli, of formic and acetic acids with Clostridium formicoaceticum, confirms and extends our earlier remarks on availability of ecotehnology for solving above problem.
