Description Microalgae culture forms an inevitable component in
aquaculture and mass culture on a commercial scale is
essential to satisfy requirement in the hatchery for use
as functional foods and nutraceuticals. However, the
current microalgal production technologies are not costeffective
and face several bottlenecks, among which is
the harvesting of microalgal biomass. Typical strategies
currently applied for harvesting microalgae include
centrifugation, filtration, various forms of flocculation
(e.g., chemical inorganic and organic agents, alkaline
flocculation, bio-flocculation using microorganisms,
and electro-coagulation), sedimentation, and flotation.
Among these harvesting methods, flocculation combined
with sedimentation of microalgal flocs is considered best
with reported cell recovery of > 90% and with low cost.
However, the biomass thus recovered with chemical
flocculant may cause harm to the final product but it is
still regarded as a promising technique. In the present
study, the flocculation efficiency of ZnCl2 and ZnSO4
were tested as chemical flocculants for the harvest of
Nannochloropsis oculata.
