Abstract
Recent progress in the applications of fine bubble technology to agriculture and marin is presented. Fine bubbles were examined in vitro to find whether antibacterial activities would be exhibited against Saccharomyces cerevisiae, Escherichia coli, Salumonella typhimulium, Staphylococcus aureus and Bacillus subtilis. Among them, Saccharomyces cerevisiae cells tended to grow well under both aerobic and anaerobic conditions by the action of microbubbles. Furthermore, the application of fine bubble technology has made it possible to give the high harvests of shrimps, seaweeds, strawberries, eggplants, tomatoes and pears. To clarify the underlying mechanism, interaction of microbubbles with a model protein, bovine serum albumin (BSA), was studied using fluorescence spectroscopy.
