SNF1 plays a crucial role in the utilization of n-alkane and transcriptional regulation of the genes involved in it in the yeast Yarrowia lipolytica. Heliyon 2024; 10:e32886. [PMID: 38975102 PMCID: PMC11226914 DOI: 10.1016/j.heliyon.2024.e32886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 06/10/2024] [Accepted: 06/11/2024] [Indexed: 07/09/2024] Open
Abstract
Yarrowia lipolytica is an ascomycetous yeast that can assimilate hydrophobic carbon sources including oil and n-alkane. The sucrose non-fermenting 1/AMP-activated protein kinase (Snf1/AMPK) complex is involved in the assimilation of non-fermentable carbon sources in various yeasts. However, the role of the Snf1/AMPK complex in n-alkane assimilation in Y. lipolytica has not yet been elucidated. This study aimed to clarify the role of Y. lipolytica SNF1 (YlSNF1) in the utilization of n-alkane. The deletion mutant of YlSNF1 (ΔYlsnf1) exhibited substantial growth defects on n-alkanes of various lengths (C10, C12, C14, and C16), and its growth was restored through the introduction of YlSNF1. Microscopic observations revealed that YlSnf1 tagged with enhanced green fluorescence protein showed dot-like distribution patterns in some cells cultured in the medium containing n-decane, which were not observed in cells cultured in the medium containing glucose or glycerol. The RNA sequencing analysis of ΔYlsnf1 cultured in the medium containing n-decane exhibited 302 downregulated and 131 upregulated genes compared with the wild-type strain cultured in the same medium. Gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses suggested that a significant fraction of the downregulated genes functioned in peroxisomes or were involved in the metabolism of n-alkane and fatty acids. Quantitative real-time PCR analysis confirmed the downregulation of 12 genes involved in the metabolism of n-alkane and fatty acid, ALK1-ALK3, ALK5, ADH7, PAT1, POT1, POX2, PEX3, PEX11, YAS1, and HFD3. Furthermore, ΔYlsnf1 exhibited growth defects on the medium containing the metabolites of n-alkane (fatty alcohol and fatty aldehyde). These findings suggest that YlSNF1 plays a crucial role in the utilization of n-alkane in Y. lipolytica. This study provides important insights into the advanced biotechnological applications of this yeast, including the bioconversion of n-alkane to useful chemicals and the bioremediation of petroleum-contaminated environments.

Simultaneous production of biosurfactant and extracellular unspecific peroxygenases by Moesziomyces aphidis XM01 enables an efficient strategy for crude oil degradation. JOURNAL OF HAZARDOUS MATERIALS 2024; 471:134437. [PMID: 38691934 DOI: 10.1016/j.jhazmat.2024.134437] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 04/03/2024] [Accepted: 04/24/2024] [Indexed: 05/03/2024]
Abstract
Crude oil is a hazardous pollutant that poses significant and lasting harm to human health and ecosystems. In this study, Moesziomyces aphidis XM01, a biosurfactant mannosylerythritol lipids (MELs)-producing yeast, was utilized for crude oil degradation. Unlike most microorganisms relying on cytochrome P450, XM01 employed two extracellular unspecific peroxygenases, MaUPO.1 and MaUPO.2, with preference for polycyclic aromatic hydrocarbons (PAHs) and n-alkanes respectively, thus facilitating efficient crude oil degradation. The MELs produced by XM01 exhibited a significant emulsification activity of 65.9% for crude oil and were consequently supplemented in an "exogenous MELs addition" strategy to boost crude oil degradation, resulting in an optimal degradation ratio of 72.3%. Furthermore, a new and simple "pre-MELs production" strategy was implemented, achieving a maximum degradation ratio of 95.9%. During this process, the synergistic up-regulation of MaUPO.1, MaUPO.1 and the key MELs synthesis genes contributed to the efficient degradation of crude oil. Additionally, the phylogenetic and geographic distribution analysis of MaUPO.1 and MaUPO.1 revealed their wide occurrence among fungi in Basidiomycota and Ascomycota, with high transcription levels across global ocean, highlighting their important role in biodegradation of crude oil. In conclusion, M. aphidis XM01 emerges as a novel yeast for efficient and eco-friendly crude oil degradation.

Sustainable production of lipids from cocoa fatty acid distillate fermentation driven by adaptive evolution in Yarrowia lipolytica. BIORESOURCE TECHNOLOGY 2024; 394:130302.

Abstract
Single cell oil production using oleaginous yeasts is a promising alternative to animal and plant-derived lipids. But substrate costs for microbial fermentation are a major bottleneck. Using side streams as alternative to substrates like glucose, for growing yeast, is a potential cost-effective solution. By combining a previously reported process of growing yeasts on a solid cocoa fatty acid distillate side stream with adaptive evolution techniques, the growth of oleaginous yeast Yarrowia lipolytica was improved by 2-fold. The lipid titre was also boosted by more than 3-fold. Using transcriptomics, key genes were identified that are possibly involved in tailoring of lipid composition, side stream utilisation and enhancement of lipid titres. Candidate genes were also identified that might enable efficient growth and utilization of fatty acids and triacylglycerides found in cocoa fatty acid distillate. In summary, this research has improved the understanding of side stream utilisation for lipid production in oleaginous yeast.

Abstract
IMPORTANCE Sustainable processes for biological upcycling of plastic wastes in a circular bioeconomy are needed to promote decarbonization and reduce environmental pollution due to increased plastic consumption, incineration, and landfill storage. Strain characterization and proteomic analysis revealed the robust metabolic capabilities of Yarrowia lipolytica to upcycle polyethylene into high-value chemicals. Significant proteome reallocation toward energy and lipid metabolisms was required for robust growth on hydrocarbons with n-hexadecane as the preferential substrate. However, an apparent over-investment in these same categories to utilize complex depolymerized plastic (DP) oil came at the expense of protein biosynthesis, limiting cell growth. Taken together, this study elucidates how Y. lipolytica activates its metabolism to utilize DP oil and establishes Y. lipolytica as a promising host for the upcycling of plastic wastes.

The Extracellular Vesicles Containing Inorganic Polyphosphate of Candida Yeast upon Growth on Hexadecane. J Xenobiot 2023; 13:529-543. [PMID: 37873811 PMCID: PMC10594515 DOI: 10.3390/jox13040034] [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: 07/31/2023] [Revised: 09/16/2023] [Accepted: 09/21/2023] [Indexed: 10/25/2023] Open
Abstract
The cell wall of Candida yeast grown on presence of hexadecane as a sole carbon source undergoes structural and functional changes including the formation of specific supramolecular complexes-canals. The canals contain specific polysaccharides and enzymes that provide primary oxidization of alkanes. In addition, inorganic polyphosphate (polyP) was identified in Candida maltosa canals. The aim of the work was a comparative study of the features of cell walls and extracellular structures in yeast C. maltosa, C. albicans and C. tropicalis with special attention to inorganic polyphosphates as possible part of these structures when grown on the widely used xenobiotic hexadecane (diesel fuel). Fluorescence microscopy with DAPI has shown an unusual localization of polyP on the cell surface and in the exovesicles in the three yeast species, when growing on hexadecane. Electron-scanning microscopy showed that the exovesicles were associated with the cell wall and also presented in the external environment probably as biofilm components. Treatment of hexadecane-grown cells with purified Ppx1 polyphosphatase led to the release of phosphate into the incubation medium and the disappearance of polyP in vesicles and cell wall observed using microscopic methods. The results indicate the important role of polyP in the formation of extracellular structures in the Candida yeast when consuming hexadecane and are important for the design of xenobiotic destructors based on yeast or mixed cultures.

Using oils and fats to replace sugars as feedstocks for biomanufacturing: Challenges and opportunities for the yeast Yarrowia lipolytica. Biotechnol Adv 2023; 65:108128.

Abstract
More than 200 million tons of plant oils and animal fats are produced annually worldwide from oil, crops, and the rendered animal fat industry. Triacylglycerol, an abundant energy-dense compound, is the major form of lipid in oils and fats. While oils or fats are very important raw materials and functional ingredients for food or related products, a significant portion is currently diverted to or recovered as waste. To significantly increase the value of waste oils or fats and expand their applications with a minimal environmental footprint, microbial biomanufacturing is presented as an effective strategy for adding value. Though both bacteria and yeast can be engineered to use oils or fats as the biomanufacturing feedstocks, the yeast Yarrowia lipolytica is presented as one of the most attractive platforms. Y. lipolytica is oleaginous, generally regarded as safe, demonstrated as a promising industrial producer, and has unique capabilities for efficient catabolism and bioconversion of lipid substrates. This review summarizes the major challenges and opportunities for Y. lipolytica as a new biomanufacturing platform for the production of value-added products from oils and fats. This review also discusses relevant cellular and metabolic engineering strategies such as fatty acid transport, fatty acid catabolism and bioconversion, redox balances and energy yield, cell morphology and stress response, and bioreaction engineering. Finally, this review highlights specific product classes including long-chain diacids, wax esters, terpenes, and carotenoids with unique synthesis opportunities from oils and fats in Y. lipolytica.
