Figure 2.

Effect of pH on photosynthetic activity of the Cyanobacterial consortium. (a) shows dark adapted quantum yield for cyanobacterial consortium grown in a starting pH of 8.5 (red) and 10.4 (green). (b,c) Showing electron transfer rates under different light intensities for 4 days of growth in lower pH (b) and higher pH (c). Numbers at the end of the lines indicate the pH measured on each day. Error bars indicate the standard deviation of six biofilm samples [Color figure can be viewed at wileyonlinelibrary.com]
