Figure 6: Visualization of endopolysaccharides using confocal laser scanning microscopy. The lyophilized samples of c-EPL, washed with MQ water, were stained for 30 min with 200 μL of 25 μg/mL Fluorescence Brightener 28 commonly used in order to detect β-linked polysaccharides. For visualization of the endopolysaccharides from C. unicolor, the inverted microscope Axiovert 200 M equipped with an LSM 5 Pascal head (with magnification 200x) was used. The letter (A) indicates the luminous areas exhibiting visible β-linked polysaccharide fragments.
