ater. Microalgae were grown at room temperature (22e24 C),
constant illumination supplied with four fluorescents lamps (TL-D
36W, Philips) and continuous mixing provided by magnetic stirrers.
The harvest was performed by centrifugation at 5000 rpm for
10 min at 4 C (Heraeus Multifuge, Germany) during the lateexponential
growth phase (i.e. approx. after 7 days).
