A brief overview is provided of the microbial oils (single cell oils - SCOs) that have been, or are still being, produced commercially. Oils rich in gamma-linolenic acid (18:3 n-6), arachidonic acid (20:4 n-6), eicosapentaenoic acid (20:5 n-3) and docosahexaenoic acid (22:6 n-3) are covered. The prospects of using other SCOs for biofuels are discussed with the conclusion that it is highly unlikely that algae will provide oils that are competitive with alternative sources of fatty acids.
Résumé
Cet article propose une brève revue des huiles microbiennes (huiles d’organismes unicellulaires, SCOs) qui ont été, ou sont toujours, commercialisées. Les huiles riches en acide gamma-linolénique (1:3 n-6), acide arachidonique (20:4 n-6), acide eicosapentaénoïque (20:5 n-3) et acide docosahexaénoïque (22:6 n-3) sont traitées. Les perspectives d’avenir de l’usage des autres SCOs en tant que biocarburants sont également discutées, avec la conclusion qu’il s’avère très improbable que les algues fournissent des huiles compététitives avec les sources alternatives d’acides gras.
