Recent advances in microalgal biotechnology.

In the last ten years, several reviews (Benemann et al, 1987; Goldman, 1979a; Richmond, 1986b; Soeder, 1980) and books (Borowitzka and Borowitzka, 1988b; Richmond, 1986a; Lembi and Waaland, 1988) have been published on the historical background of mass cultivation of microalgal biomass, and its possible commercial applications. This review presents a brief description of the concept of microalgal biotechnology, and describes some of the recent developments, mainly in the application and commercial development of this relatively new biotechnology, Finally, an attempt is made to indicate those areas where current research and development are paving the way for future applications.
