Abstract

a. La culture des micro-organismes s'effectue ici sur des hydrocarbures comme sources de carbone pour obtenir des protéines unicellulaires. b. On choisit, comme hydrocarbures, des fractions à température d'ébullition plus élevée que les fractions choisies habituellement à cette fin, dont le nombre d'atomes de carbone est égal au moins à 17 en moyenne, et on prolonge la durée de séjour dans la cuve de fermentation pendant au moins 5 heures. c. La production de biomasse est plus importante avec une consommation moindre d'énergie et une meilleure utilisation de l'hydrocarbure et de l'oxygène.at. The culture of microorganisms is carried out here on hydrocarbons as carbon sources to obtain unicellular proteins. b. As hydrocarbons, fractions with a higher boiling temperature than the fractions usually chosen for this purpose, the number of carbon atoms of which is equal to at least 17 on average, are chosen, and the residence time in the tank is extended. fermentation tank for at least 5 hours. vs. Biomass production is greater with less energy consumption and better use of hydrocarbons and oxygen.
