Figure 2From: Cell–cell and cell–surface interactions in an illuminated biofilm: Implications for marine sediment stabilization†Bioreactors containing glass beads (100 μm). Upper bioreactor was inoculated with A. coffeaeformis 10 d previously. At this time diatoms were no longer growing and matrix polymer formation was well developed. Lower bioreactor is uninoculated control. Note avalanching of beads in the uninoculated control.Back to article page
