The results obtained (Fig. 1), showed BC productions
of 0.81 0.04 g L1 for DOR40 and 0.85 0.04 g L1 for
DOR100, which corresponded respectively to 32 and 34% of the
production achieved with conventional HS culture medium
(w2.5 g L1). Finally for DOR100H, despite the higher amounts
of monosaccharides available, there was no BC production,
which was certainly due to the formation or release of organic
compounds such as furfural during the hydrolysis step,
resulting from sugar degradation and also phenolic compounds,
which could have inhibited the metabolism of G.
sacchari and consequently BC production [3]. So, unless laborious
processes for inhibitors removal are used, the hydrolysed
aqueous extract DOR100H is not suited for BC
production.
