Abstract
OBJECTIVES This study aimed to isolate red yeast from sap, bark and slime exudates collected from Polish birch forests and then assessment of their biotechnological potential. RESULTS 24 strains of red yeast were isolated from the bark, sap and spring slime fluxes of birch (Betula pendula). Strains belonging to Rhodotorula mucilaginosa (6), Rhodosporidiobolus colostri (4), Cystrofilobasidium capitaum (3), Phaffia rhodozyma (3) and Cystobasidium psychroaquaticum (3) were dominant. The highest efficiency of carotenoid biosynthesis (5.04 mg L-1) was obtained by R. mucilaginosa CMIFS 004, while lipids were most efficiently produced by two strains of P. rhodozyma (5.40 and 5.33 g L-1). The highest amount of exopolysaccharides (3.75 g L-1) was produced by the R. glutinis CMIFS 103. Eleven strains showed lipolytic activity, nine amylolytic activity, and only two proteolytic activity. The presence of biosurfactants was not found. The growth of most species of pathogenic moulds was best inhibited by Rhodotorula yeasts. CONCLUSION Silver birch is a good natural source for the isolation of new strains of red yeast with wide biotechnological potential.

BIORESOURCE TECHNOLOGY 2023; 384:129379. [PMID: 37352986 DOI: 10.1016/j.biortech.2023.129379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 06/19/2023] [Accepted: 06/20/2023] [Indexed: 06/25/2023]
Abstract
The study reports the exploration of the transcriptome landscape of the red oleaginous yeast Rhodotorula mucilaginosa IIPL32 coinciding with the fermentation kinetics of the yeast cultivated in a two-stage fermentation process to exploit the time-series approach to get the complete transcripts picture and reveal the persuasive genes for fatty acid and terpenoid synthesis. The finding displayed the molecular drivers with more than 2-fold upregulation in the nitrogen-limited stage than in the nitrogen-excess stage. The rate-limiting diphosphomevalonate decarboxylase, acetylCoA-citrate lyase, and acetyl-CoA C-acetyltransferase were significant in controlling the metabolic flux in the synthesis of reduced compounds, and acetoacetyl-CoA synthase, 3-ketoacyl-acyl carrier-protein reductase, and β-subunit enoyl reductase catalyze the key starting steps of lipids or terpenoid synthesis. The last two catalyze essential reduction steps in fatty acid synthesis. These enzymes would be the prime targets for the metabolic engineering of the oleaginous yeast for enhanced fatty acids and terpenoid production.

Integrative analysis of genomic and metabolomic data reveals key metabolic pathways involved in lipid and carotenoid biosynthesis in oleaginous red yeast Rhodosporidiobolus odoratus XQR. Microbiol Res 2023; 270:127339. [PMID: 36827895 DOI: 10.1016/j.micres.2023.127339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 02/04/2023] [Accepted: 02/18/2023] [Indexed: 02/23/2023]
Abstract
Rhodosporidiobolus odoratus, one of the oleaginous red yeasts, is gaining biotechnological importance for their ability to produce microbial lipids and carotenoids. However, to date, the genomic resource underling lipid and carotenoid biosynthesis in R. odoratus has not been reported. Here, we reported the first genome assembly of R. odoratus using a combination of PacBio and Illumina techniques. The final genome assembly is 23.74 Mb in size, containing 52 scaffolds with a N50 length of 1200,460 bp and a GC content of 56.90%. Benchmarking Universal Single-Copy Orthologs (BUSCO) assessment showed that our assembly contains 94.23% of Basidiomycota universal single-copy orthologs. The genome was predicted to contain 4986 protein-coding genes, 4967 of which were functionally annotated. Metabolomic profiling identified 574 lipids, 3 carotenoids, and 208 volatile organic compounds synthesized by R. odoratus. Integrative analysis of genomics and metabolomics provides insights into the biosynthesis of lipid, carotenoid, and other bioactive compounds in R. odoratus. Collectively, the results presented herein greatly enhance our understanding of R. odoratus in lipids and carotenoids biosynthesis, and thus further accelerate its fundamental molecular investigations and biotechnological applications.

Strain ATL72 for Enhancing Its Biotechnological Applications. J Fungi (Basel) 2022; 8:jof8020160. [PMID: 35205915 PMCID: PMC8877855 DOI: 10.3390/jof8020160] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Revised: 01/29/2022] [Accepted: 01/30/2022] [Indexed: 02/04/2023] Open
Abstract
Rhodotorula yeasts which are known as carotenogenic yeasts have a great industrial value due to their ability to produce carotenoids. In particular, the isolated yeast Rhodotorula sp. (strain ATL72) has been reported to be a promising producer of high concentrations of carotenoids. A combination of central composite design (CCD) and Plackett–Burman (PB) design was used to optimize carotenoids produced by this yeast. The optimum production of carotenoids was completed when the yeast was grown in a production medium composed of 3.7 g/L malt extract, 7.7 g/L fructose, 9 g/L urea, 35 g/L NaCl, and 1 g/L yeast extract at 27.5 °C, pH 6.7, and 180 rpm. Two batch runs in 1 L and 7 L bioreactors were conducted which increased the productivity of carotenoid concentration from 21.5 mg/L after 98 h of incubation at the level of the shake flask to 229.9 mg/L after 47 h of incubation at the level of 7 L bioreactor. The carotenoid pigment was extracted in dimethylsulfoxide (DMSO), acetone, petroleum ether, and sodium chloride, and subsequently identified and characterized using UV-visible scanning, thin layer chromatography, and gas chromatography/mass spectrometry.
