BACKGROUND Carotenoids are multifunctional, taxonomically widespread and biotechnologically important pigments. Their biosynthesis serves as a model system for understanding the evolution of secondary metabolism. Microbial carotenoid diversity and evolution has hitherto been analyzed primarily from structural and biosynthetic perspectives, with the few phylogenetic analyses of microbial caroten...

the potential use of date syrup, for the production of carotenoids by rhodotorula glutinisin batch fermentation process, was investigated during 7 days. the results revealed that carbon (glucose or date syrup) and nitrogen sources [yeast extract, (nh4)2so4 and nh4no3] had a significant influence on biomass and carotenoid production. maximum yield of total carotenoid production (7.94 mg/l) with ...

Nowadays, carotenoids are valuable molecules in different industries such as chemical, pharmaceutical, poultry, food and cosmetics. These pigments not only can act as vitamin A precursors, but also they have coloring and antioxidant properties, which have attracted the attention of the industries and researchers. The carotenoid production through chemical synthesis or extraction from plants is ...

The opportunities to understand eubacterial carotenoid biosynthesis and apply the lessons learned in this field to eukaryotes have improved dramatically in the last several years. On the other hand, many questions remain. Although the pigments illustrated in Fig. 2 represent only a small fraction of the carotenoids found in nature, the characterization of eubacterial genes required for their bi...

Recent research interest in phytochemicals has consistently driven the efforts in the metabolic engineering field toward microbial production of various carotenoids. In spite of systematic studies, the possibility of using C30 carotenoids as biologically functional compounds has not been explored thus far. Here, we generated 13 novel structures of C30 carotenoids and one C35 carotenoid, includi...

Carotenoid production from oleaginous red yeast has been considered as a safe alternative to chemically synthesized carotenoids commonly used in the food industry, since plant-based are expensive and an irregular source for obtaining pigments. This is summative review on factors affecting carotenoid production, cost-effective strategies using various inexpensive feedstock, metabolic engineering...

Carotenoids are one of the most important and widely distributed pigments in nature and have essential biological functions in organisms. They also impart distinctive and attractive coloration to the breeding animals. Over the past two decades, application of microbial carotenoids has attracted the attention of researchers due to their natural and economic advantages. However, carotenoid produc...

Article history: Received: 29 May 2013 Accepted: 21 Aug 2013 Available online: 12 Oct 2013 ZJRMS 2015 Feb; 17(2): 52-56 Background: Rhodotorula is characterized by the absence of ballistoconidia, fermentation ability, and starch-like compounds. Biology of the species is not well-identified; therefore molecular identification is required. Sequence analysis of the D1/D2 region can be used for the...
