Fig. 2

Heat map of gene frequencies for selected characteristics in the biofilm and planktonic populations. The figure shows percentage gene frequencies for modern marine biofilms formed on glass (MMBG) and garnet (MMBR) compared to modern marine planktonic large (MMPL) and small (MMPS) cells and old saline biofilms formed on glass (OSBG) and garnet (OSBR) compared to duplicate metagenomes for both the old saline planktonic large (OSPL) and small (OSPS) cells. The frequencies for CO2 fixation are based upon the presence of the cbbLMS genes coding for the Enzyme Commission number (EC) 4.1.1.39; nitrogen fixation is for EC 1.18.6.1 encompassing the nifKDH genes; and sulfate reduction is solely based upon dsv as no dsrAB genes were identified. In addition, frequencies are shown for the Rnf complex as well as for the individual genes. Statistics are presented when the difference between biofilm values for garnet and glass (number of replicates =1 each) compared to large and small planktonic cells (number of replicates =2 each) have p values <0.05 or <0.01 (p values were not calculated for the individual Rnf genes)
