Micro-algal Biotechnology Group

Contents

Introduction

Stephen

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
