“…The removal efficiencies for COD, TN, TP, CH 3 ‐N and orthophosphate by Scenedesmus sp. were carried out according to APHA 14 . The removal efficiency ( E ) was calculated according to Eqn (2):

E = \frac{C_{i} - C_{f}}{C_{i}} \times 100

where C i is the initial concentration (mg L –1 ) and C f is the remaining concentration (mg L –1 ).…”

Meat production is associated with the generation of huge quantities of meat processing wastewater (MPWW) which has high concentrations of nutrients. The utilization of Scenedesmus sp. in the phycoremediation process to treat MPWW has attracted growing interest, but there is inadequate information on the management of biomass of this microorganism. This study aims to optimize the harvesting of Scenedesmus sp. biomass generated during phycoremediation through flocculation with alum and its potential biomass by-product. The removal rates of the chemical oxygen demand, ammonia, total nitrogen, total phosphorus and orthophosphate were 99.16% (R 2 = 0.95), 97.19% (R 2 = 0.91), 93.91% (R 2 = 0.96), 97.25% (R 2 = 0.85) and 99.38% (R 2 = 0.9517), respectively. From the result, the best coagulant for recovery efficiency (97.54%) was recorded at pH 8.6 with 116.85 mg L −1 alum. Three major chemical compoundstetradecanoic, oleic and dodecanoic acidswere recorded in the extraction of Scenedesmus sp. biomass (as determined by gas chromatography-mass spectrometry analysis; these have the potential for use in the cosmetic and medical industries. The main functional groups in the harvested biomass were OH, CH, CO -C and CH CH. It can be concluded that the flocculation method was the most efficient compared to filtration process for recovering Scenedesmus sp. biomass owing to the absence of toxic by-products.

Rapid growing of human population has led to increasing demand of aquaculture production. Oreochromis niloticus or known as tilapia is one of the most globally cultured freshwater fish due to its great adaptation towards extreme environment. Besides, farming of tilapia not only involves small scales farming for local consumption but also larger scales for international market which contributes to a foreign currency earning. Extensive use of fishmeal as feed for fish and for other animals indirectly caused an increasing depletion of the natural resource and may consequently cause economic and environmental unstable. Microalgae biomass seems to be a promising feedstock in aquaculture industry. It can be used for many purposes such as live food for fish larvae and dried microalgae to substitute protein material in fish feed. The microalgae replacement in fish feed formulation as protein alternative seem potentially beneficial for long term aqua-business sustainability. The present chapter discussed the potential of microalgae as an alternative nutrition in fish feed formulations, specifically Tilapia.
