2.5 Toxicity of MEA on Bacteria and Microorganisms

Liuzinas et al. (2007) conducted a laboratory scale study on the investigation on the toxicity of MEA on microorganisms via paper disc and wells methods for the determination of toxicity of MEA waste on bacteria and microorganisms. From the investigation it was observed that the toxicity test using method of wells is more sensitive in comparison to the method of disc. Escherichia coli was the most sensitive for higher concentrations of MEA among the investigated bacteria. It was observed that the toxicity of MEA is higher in bacteria. MEA at concentrations of 5–25% have influence on some bacteria: fungistatical influence at 5% and fungicidal influence at 25%. Addition of MEA waste at various concentrations were made onto the bacteria and microorganisms and the results were tabulated as in Tables 4 and 5, respectively.Table 4Sensibility of bacteria to various concentrations of MEA (method of paper discs) (Liuzinas et al. 2007)
