Scanning electron micrographs of the strain B23 cells before (a) and after (b) cultivation on LBM supplemented with 0.1% (v/v) alkanes. Cells were grown without shaking at 70°C for 14 days. The bars indicate the size of 5 μm. Background of the cells is cellulose fibers of filter paper on which cells are adsorbed and fixed.
