摘要：

''Is it possible to incorporate a living microorganism as a second phase in a man-made, engineered material?'' In this preliminary study, Saccharomyces cerevisiae has been encapsulated in a transparent matrix of porous, gel-derived silica. After gelation, aging, and prolonged storage at 5 degrees C, S. cerevisiae bioactivity could be triggered. Bioactivity was followed by evolution of alcohol within the S. cerevisiae as a function of time during incubation by the molecular probe molecule pyranine using fluorescence spectrophotometry. Described also are some of the potential applications of this new class of biocomposite material incorporating a ''living'' second phase.
