Conversely, in the fermentation of xylose and xylan, the t-values
attained were inferior to 0.05, which denotes that LE58 was significantly more efficient than LE37 when using xylose or xylan as carbon and energy source. As already stated, glucose and starch are
major components of S. obliquus biomass. Higher H2 production
associated to the use of these substrates, as attained by LE37, point
out to a more efficient fermentation of the microalgal biomass than
by LE58. Another relevant condition for the comparison between
LE37 and LE58 relies in the fermentation operational settings.
Processes performed at 58 C are generally less likely to be affected
by contamination while improving biomass degradation and sugar
dissolution into the medium [33]. However, they are also energetically more costly and, considering that the process involves mixed
cultures, the impact of a contamination would not be as important.
