ABSTRACT
An overview of the various aspects, promises and limitations of microalgal
biotechnology is presented. The factors of importance in microalgal cultivation
as well as the culture systems are briefly described. Microalgal biomasses can
f u l f i l the nutritional requirements of aquatic larvae and organisms. The
biochemical composition of algae can be improved by the manipulation of culture
conditions. The nutritive value of the microalgal biomasses for human and animal
consumption is also commented upon as well as some socio-economical aspects.
Among the sources of required nutrients (N, P), wastewaters and manures can
upgraded as culture media for microalgae the safety of which has to be evaluated.
Harvesting of the biomass is one of the bottlenecks. The various techniques,
physical, physico-chemical and biological are outlined and their feasibility and
economic interest examined. Microalgal biomasses can be submitted to various
technological transformations. Various processes are reviewed in the light of
their effects on safety and nutritional value. The possible extraction of fine
chemicals and the preparation of protein concentrates is also reported on. The
various uses of microalgae lead to a possible competition, to be evaluated,
between systems for the production of food, energy and chemicals. The review
finally covers the application of genetic manipulation to microalgae.
