Growth of mixotrophic Scenedesmus cultures incubated for five days in hermetically with septa closed bottles without [control (5 days)] and with different m-dcps.

a)OD was measure with a specific absorbance cuvette (10×5×45 mm).b)OD values higher than 0.8 were measured and calculated after the appropriate sample dilution.c)Number of cells was measured using Neubauer chamber.Control (day 0) represents the culture start point for all the tested treatments. OD550: optical density of the culture at 550 nm, DW: dry weight, PCV: packed cell volume.
