title: [Effect of organic acids on the biosynthesis of carotenes by an Actinomyces chrysomallus strain].
abstract: Synthesis of carotenes by Actinomyces chrysomallus var. carotenoides was stimulated by citric, acetic, oxalacetic, fumaric, succinic, malic, alpha-ketoglutaric, tartaric, pyruvic, and propionic acids. Acetic acid acts as a precursor of carotene synthesis and also has another stimulating mechanism of action on carotenogenesis of the actinomycete. Acetic, furmaric, malic, succinic, and alpha-ketoglutaric acids stimulate cyclization of lycopene yielding beta-carotene.
