indicating that there was no relevant growth based on a non photosynthetic process.
Microalgal biomass produced in all experiments
is composed of approximately 40 - 50%
organic carbon.
C. fusca
and
S. obliquus
are the algal species that present a higher degree of
autoflocullation, then being more easily separated from the liquid phase. However, Cr(VI) ≥ 5
mg l
-1
impairs algae autoflocculation particularly of
C. vulgaris
and
S. acutus
cultures. For
Cr(VI) ≤ 1 mg l
-1
only
C. vulgaris
flocs present a low settling rate.
