Rhodotorula benthica is a unicellular yeast strain and presents widely in ocean with rich compositions of proteins, carotenoids, vitamins, digestive enzymes, and other biologically active substances. It has been applied in many fields including food, feed, medicine, and water industry. Rhodotorula species grow rapidly at 30 ℃ with coral pink, smooth, and moist to mucoid fettle, while the growth at 37 ℃ is variable. Rhodotorula species are strict aerobic yeasts with peculiarly metabolic characteristics. Rhodotorula produces urease and it has the inability to assimilate inositol and ferment sugars. Moreover, it is well known as a good source of carotenoids, proteins, essential amino-acids, digestive enzymes, lipids and vitamins. Rhodotorula benthica possesses a broad utilization prospect based on its metabolites, structures and bioactivities. This review summarizes some advances on the types, structures, and biological applications of the isolates from Rhodotorula glutinis.
