series of batch assays were undertaken in order to evaluate
the capability of LE37, LE58 and C. butyricum to produce H2 from
different carbon and energy sources, including sugars identified
in the composition of S. obliquus biomass [15,21]. It is known that
S. obliquus is able to store sugars in the form of intracellular starch
and that glucan and xylan may also exist in the microalgae cell
walls, as well as extracellular polymeric substances
