Exploration of carotenoid-producing <i>Rhodotorula</i> yeasts from amazonian substrates for sustainable biotechnology applications.

ABSTRACT: Carotenoids are natural pigments responsible for the yellow, orange, and red colors seen in various organisms. The aim of this study was to investigate the potential of yeast strains belonging to the genus Rhodotorula isolated from the Amazon Region in the production of carotenoids. Environmental samples from the Amazon Region were collected for yeast isolation. Isolates showing pigmented colonies underwent morphological and biochemical studies, as well as assessment of their potential for carotenoid production. The three best producers were identified through nucleotide sequencing of the ITS1-5.8s-ITS4 rDNA region. The top producer underwent univariate experiments to evaluate the influence of different C/N sources. Carotenoids produced were evaluated using CCD. Results showed the i
