FIG. 1.

Fates of MS2, R17, and φX174 during batch experiments in which glass tubes were packed with varying numbers of Teflon and glass beads. A surface area of 0 cm² implies that tubes were filled only with glass beads. An AWI was present in all batch experiments. Data are means from three experiments; error bars represent the standard deviations from the means. r² values from the regression analysis are given in the text.
