Removal of B. pumilus cell surface-bound DNA and RNA molecules with nucleases. Green fluorescence denotes cell surface-bound DNA and RNA of B. pumilus stained with the membrane impermeable SYTOX Green dye. A DIC (left), SYTOX Green (center), and merged (right) images of control and DNase/RNase-treated B. pumilus at 100 × magnification. Scale bars represent 2 μm.
