Effect of the culture system and culture technique on biochemical characteristics of Pavlova lutheri and its nutritional value for Crassostrea gigas larvae
Pavlova lutheri was cultivated in carboys using batch technique and in a flat alveolar photobioreactor (FAP), using initially batch and then semi-continuous techniques. Growth and productivity of the cultures were compared and their nutritional quality was assessed by analysing their biochemical com...
