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

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.

Yeasts found in vineyards and wineries

“…Outside of wine, Rhodotorula spp. have received considerable research attention owing to a high accumulation of fatty acids and carotenoids (reviewed by Ageitos et al ., ; Frengova and Beshkova, ; Kot et al ., ). Some Rhodotorula species, particularly R .…”

“…Outside of wine, Rhodotorula spp. have received considerable research attention owing to a high accumulation of fatty acids and carotenoids (reviewed by Ageitos et al, 2011;Frengova and Beshkova, 2009;Kot et al, 2016). Some Rhodotorula species, particularly R. glutinis and R. turoloides, can accumulate up to 66 and 76%, respectively, of their dry weigh as lipids (Ageitos et al, 2011).…”

Co‐utilization of acidified glycerol pretreated‐sugarcane bagasse for microbial oil production by a novel Rhodosporidium strain

“…It is worth noting that the strain R. glutinis ATCC 204091 (also reported as Rh. toruloides ATCC 204091 and used in this study) only accumulated 25–42% oils in the cell mass from different studies [ and references therein]. However, a recent study reported a 77% oil content with R. glutinis ATCC 204091 through a two‐step cultivation strategy .…”

Biotransformation of α-Acetylbutyrolactone in Rhodotorula Strains

“…Rhodotorula is included in the order Sporidiobolales , class Microbotryomycetes , and phylum Basidiomycota in the Fungi kingdom [1]. Species of this genus are ubiquitous saprophytic yeasts that can be acquired from many environmental sources including air, soil, grass, lakes, oceans, food, and human skin [1,2].…”

“…Species of this genus are ubiquitous saprophytic yeasts that can be acquired from many environmental sources including air, soil, grass, lakes, oceans, food, and human skin [1,2]. Rhodotorula ’ s biomass can also be a valuable addition to animal feed because these strains synthetize carotenoids: β-carotene, torulene, and torularhodin (a typical feature of this species is red colour of cells) [3,4].…”
