9 days, and that glucose was completely consumed
after 11 days. However, in the present study, the glucose consumption
slowed down after day seven and in order to achieve higher efficiency
(i.e., saving of energy and time), the process was terminated and
the products isolated. A relatively high biomass (mycelia) yield of
6.63 ± 0.31 g DW L−1 was achieved as well as a significant yield of
exopolysaccharides, 0.74 ± 0.12 g L−1. Xu, Kim, Hwang, Choi, and Yun
(2003) showed that optimisation of submerged mushroom cultivation
is critical for higher yields ofmycelia and exopolysaccharides. According
to the same authors, the optimal glucose concentration, as well as the
concentrations of other nutrients, for mycelia and exopolysaccharides
