Chitosan enhances gas vesicle flotation
As was seen in our experiments, addition of even small quantities of chitosan led to a notable increase in the hydrodynamic radius of the nano-particles and a significant effect on the rate of decrease of optical density. To verify that the gas vesicles were actually floating, images of gas vesicle suspensions were taken at regular intervals over two hours. It was found that while native gas vesicles retained an almost uniform distribution throughout the column, the suspension containing chitosan treated gas vesicles quickly cleared up.
