Thus, the objective of the present study is to evaluate the potential
of using organic fertilizer to cultivate Chlorella vulgaris. Various
culture parameters such as amount of nitrates, illumination duration,
pH, outdoor cultures and the effect of reuse the recycling
water were systematically investigated. All experiments were performed
using 5 L photobioreactor (except seed culture) instead of
using lab scale conical flask and tap water was used rather than
using distilled or sterilized water. This approach was implemented
to promote an easier up-scaling and to minimize the overall energy
consumption in cultivating microalgae in commercial scale.
