title: Evaluation of usefulness of 2DCorr technique in assessing physicochemical properties of bacterial cellulose.
abstract: The main aim of the current study was to evaluate the usefulness of the two-dimensional correlation analysis (2DCorr) technique in assessing the physicochemical properties of bacterial cellulose (BC) depending on the synthesis time and Komagataeibacter xylinus strain used for its production. It was demonstrated that 2DCorr analysis allows to characterize substantial changes in the structure of BC at the molecular level occurring during its synthesis, which are difficult to determine using ATR-FTIR spectral analysis. Furthermore, it was found that 2DCorr analysis allows to identify the differences in the structure and the properties of BC according to the bacterial strain used for its synthesis. It was concluded that 2DCorr analysis of the ATR-FTIR spectra may be a useful tool for controlling BC production in order to obtain material with the desired properties.
