L’un des moyens de réduire les coûts de production des biosurfactants est d’ajouter de la valeur à la biomasse et à l’extrait du micro-organisme producteur. Par exemple, la production in vitro de surfactines a un faible rendement et implique la culture de Bacillus subtilis dans des milieux synthétiques en utilisant des substrats coûteux. Au cours de la croissance, la surfactine et d’autres lipopeptides et enzymes importants pour l’industrie pharmaceutique, l’industrie alimentaire et la production d’éthanol, tels que l’alpha-amylase, la lipase et la cellulase, sont produits et sécrétés dans le milieu de culture. À la fin de la croissance microbienne, l’extrait est séparé de la biomasse par centrifugation. Cette biomasse, qui serait autrement jetée, est une source de protéines et de lipides, avec des applications potentielles pour la synthèse d’autres tensioactifs, et peut également être utilisée pour la décontamination de l’environnement. L’objectif principal de ce travail est de présenter des alternatives pour réduire les coûts de production des surfactines.
