Rhodotorula glutinis-potential source of lipids, carotenoids, and enzymes for use in industries

Appl Microbiol Biotechnol. 2016 Jul;100(14):6103-6117. doi: 10.1007/s00253-016-7611-8. Epub 2016 May 21.

Abstract

Rhodotorula glutinis is capable of synthesizing numerous valuable compounds with a wide industrial usage. Biomass of this yeast constitutes sources of microbiological oils, and the whole pool of fatty acids is dominated by oleic, linoleic, and palmitic acid. Due to its composition, the lipids may be useful as a source for the production of the so-called third-generation biodiesel. These yeasts are also capable of synthesizing carotenoids such as β-carotene, torulene, and torularhodin. Due to their health-promoting characteristics, carotenoids are commonly used in the cosmetic, pharmaceutical, and food industries. They are also used as additives in fodders for livestock, fish, and crustaceans. A significant characteristic of R. glutinis is its capability to produce numerous enzymes, in particular, phenylalanine ammonia lyase (PAL). This enzyme is used in the food industry in the production of L-phenylalanine that constitutes the substrate for the synthesis of aspartame-a sweetener commonly used in the food industry.

Keywords: Oleaginous yeast; Phenylalanine ammonia-lyase; Torularhodin; Torulene; β-Carotene.
