Combination of Tucker3 model with cluster analysis for the assessment of the microbiological activity on benzimidazolium salts

The antimicrobial effect of 7 benzimidazolium salts (base, chloride, sulfate, phosphate and nitrate forms) was determined on 15 microorganisms. The similarities and dissimilarities among the data consisting of the benzimidazolium salts and microorganisms were elucidated by using the Tucker model combined with cluster analysis. The calculations demonstrated that the combined method can be successfully employed for the separation of the impact of the molecular structure and cation type on the antimicrobial activity of the base and benzimidazolium salts.
