Abstract

The possibility of utilizing volatile fatty acids (VFA)-containing waste substrates from biotechnological and industrial processes was investigated by cultivating both oleaginous (Candida sp., Rhodotorula glutinis, Trichosporon cutaneum, Yarrowia lipolytica) and non-oleaginous (Kluyveromyces polysporus, Saccharomyces cerevisiae, Torulaspora delbrueckii) yeast species on acetic acid, propionic acid and a combination of either acid with glucose as carbon and energy sources. Both oleaginous and non-oleaginous yeasts grew on VFA. Oleaginous yeasts accumulated lipids to 15-48% of dry cell weight, non-oleaginous yeasts also grew on VFA and showed comparable biomass yields but the lipid content was only 2-5%. Biomass and lipid yield increased in cultivations on VFA plus glucose. The lipid composition was comparable to plant-derived oils and therefore might be exploitable in biodiesel production; nearly all species, when cultured on propionate, showed a high content of the desirable odd-chain unsaturated FA, especially 17:1 acid. This study points at the wide array of possible applications of many yeasts, even non-oleaginous strains, for biovalorization of industrial wastes. Despite their low lipid content these species are useful beca...Continue Reading

Biofuels (ASM)

Biofuels are produced through contemporary processes from biomass rather than geological processes involved in fossil fuel formation. Examples include biodiesel, green diesel, biogas, etc. Discover the latest research on biofuels in this feed.
