Аннотация доклада:
The objectives were to develop a cheap one-step “green” method of processing of BC membranes, providing simultaneous purification (depyrogenation) and sterilization. We achieved the several-fold reduction of endotoxin content in BC films. Under certain conditions, the producer cells’ outer membranes were destroyed during processing, but bacterial cells still preserved their shape and dimensions. Addition of H2O2 as a co-solvent improved the purification process. The partial removal of the bacterial lipopolysaccharides were detected and visualized
