Abstract
A series of commercial powdered media (Cell-Hi F2P, JWP and WP) and a hydroponics medium (FloraMicroBloom) were investigated for the cultivation of P. tricornutum, and compared with f/2 (a commonly employed laboratory cultivation medium; costlier to scale). Cell-Hi JWP showed good performance characteristics including cost-effectiveness. Outdoor cultivation of P. tricornutum in an airlift photobioreactor, using Cell-Hi JWP in the United Kingdom (UK) during September and October (average daily temperature ranging between 8 and 18 °C and natural sunlight) was comparable to cultivation indoors under controlled temperature and lighting. A strong positive correlation between fucoxanthin and chlorophyll a content, and a weak inverse correlation between eicosapentaenoic (EPA) content and temperature were observed. Commensal bacterial counts revealed a sinusoidal growth profile with a change in community dominance from Halomonas sp. to Marinobacter sp. This investigation reveals for the first time that a multi-product approach can be adopted with P. tricornutum in a UK outdoor environment using commercially viable powdered media.
