Conference: Oleaginous yeasts: producing high-value products from organic wastes by single-cell organisms

Speaker: Dr. Elia Tomás-Pejó (Senior Assistant Researcher from the Biotechnological Processes Unit)

Short- bio

Dr. Tomás-Pejó received her PhD with International Mention from the Universidad Complutense of Madrid in 2009. After that, she worked as post-doctorate at CIEMAT for one year. After this period, she joined as post-doctorate the Industrial Biotechnology Group at Chalmers University of Technology (Sweden) for 3 years. In 2014, she was awarded with a MARIE Courie-AMAROUT grant to join the Biotechnological Processes Unit at IMDEA Energy where she is Assistant Senior Researcher. 

Dr. Tomás-Pejó was principal investigator of the project LIGNOYEAST (ENE2014-54912-R) and she is currently co-leading 1 national project (ACMIBIO_AD, ENE2017-86864-C2-1-R). She is also chairing the COST Action YEAST4BIO CA18229. Besides, she is principal investigator from IMDEA Energy for one national (BIO_LIGWASTE, RTC-2016-5281-5) and one international project (BIOGASMENA, ERANETMED2-72-026).


Economically viable conversion of low-cost renewable feedstock into biofuels and biochemicals is of utmost importance for the establishment of a robust bioeconomy. In this context, the use of microorganisms for the generation of bioproducts from renewable resources offers many advantages.

Non-conventional yeasts are attracting more and more attention owing to their potential to metabolize complex carbon sources, their alternative metabolic routes and their ability to cope with wide range of process conditions. Additionally, some yeast species (i.e. oleaginous yeasts) can accumulate lipids up to 60-70% of their biomass. The ability of non- conventional oleaginous yeasts to accumulate high quantities of lipids offers the commercial potential for production of lipids or “single-cell oils”, advanced biofuels generation and accumulation of lipid-soluble fine chemicals of high value, such as carotenoids and surfactants.

Recent advances in anaerobic digestion have facilitated research efforts in the utilization of carboxylates platforms for the biotechnological production of biofuels and (fine) biochemicals. In this sense, we propose the resulting carboxylic acids as platform molecules for their conversion into bioproducts by non-conventional yeasts.
