Organization of cellulose fibrils in the capsular matrix of <em>Acidisarcina polymorpha </em>SBC82<sup>T </sup>identified by synchrotron radiation
A structural study of the cellulose-containing capsular matrix of <em>Acidisarcina polymorpha </em>SBC82<sup>T</sup> was carried out using synchrotron radiation. Analysis of the diffraction pattern from a 45-day-old population of acidobacteria revealed that the crystalline structure of the capsular matrix, formed by cellulose fibrils with cylindrical symmetry, is well described by a two-dimensional hexagonal lattice. Processing of diffraction data allowed us to calculate the radius of fibrils in the main (17.0 ± 0.5 A) and additional (10 ± 5.9 A) directions and their mass ratio (9 : 1), as well as to estimate the size of the crystalline domain of the capsules (50 nm).
