Variations of cumulative hydrogen production, concentration of cell, glucose, and volatile fatty acids over time under various lactic acid-producing bacteria/purple non-sulfur photosynthetic bacteria (LAB/PNSB) ratios and a fix LAB concentration of 0.03 g/L. LAB only (LAB concentration = 0.03 g/L) (a); LAB/PNSB ratio of 1/2 (LAB concentration = 0.033 g/L, PNSB concentration = 0.067 g/L) (b); LAB/PNSB ratio of 1/7 (LAB concentration = 0.031 g/L, PNSB concentration = 0.219 g/L) (c). Hydrogen (black circle), glucose (red triangle), cell (blue diamond), lactic acid (green square), formic acid (blue cross)
