Introduction

The objective of the Microalgal Biotechnology Group is to further the understanding of the ecology of microalgae. This will assist with the development of commercial-scale microalgal culturing techniques for the production of bioactive compounds, aquaculture feed, fine chemicals, and renewable fuels. Additionally, environmental applications such as CO₂ bioremediation, control of excessive algal growth and development of management strategies for water supply managers are investigated. The Microalgal Biotechnology Group is a part of a national research group (BEAM), which focuses on photosynthetic light utilisation efficiency and carbon fixation, chlorophyll fluorescence, biochemistry of secondary metabolites, molecular biology and photo-bioreactor design and engineering.

Purpose/Aims

The School of Chemical Engineering has established the Microalgal Biotechnology Research group with the following aims:

• To conduct world-class research in microalgal biotechnology, through the consolidation of ideas, experience and expertise.
• To establish links with international research organisations and to encourage joint research
• To promote exchange of students and researchers
