Abstract
An oleaginous yeast strain of the species Trichosporon oleaginosus, deposited on May 28, 2020 at Leibniz-Institut DSMZ, deposit number DSM 33530 can be used in the production of lipids by fermentation and was obtained by mutagenesis and subsequent selection from the oleaginous yeast strain of the species Trichosporon oleaginosus DSM 32508. The strain DSM 33530 is characterized by high thermotolerance, such as to allow the fermentation temperature to be increased compared to conventional processes and still guarantee the vital functions of the microorganism during fermentation itself.
Claims9
The oleaginous yeast strain of the species Trichosporon oleaginosus, deposited on 28 May 2020 at Leibniz-Institut DSMZ, deposit number DSM 33530.
A process for lipid production including the following steps:
- preparing an inoculum comprising the oleaginous yeast strain of the species Trichosporon oleaginosus DSM 33530,
- feeding said inoculum to a culture device obtaining a culture broth,
- subjecting said culture broth to fermentation so as to obtain an oleaginous cell biomass comprising lipids in suspension in an aqueous phase,
- separating the oleaginous cell biomass comprising lipids from the aqueous phase, and
- recovering the lipids present in the oleaginous cell biomass.
