A psychrotrophic marine strain of the ascomycetous yeast Yarrowia lipolytica (NCYC 789) synthesized silver nanoparticles (AgNPs) in a cell-associated manner. These nanostructures were characterized by UV-Visible spectroscopy and scanning electron microscope-energy dispersive spectrometer (SEM-EDS) analysis. The brown pigment (melanin) involved in metal-interactions was obtained from the cells. This extracted pigment also mediated the synthesis of silver nanoparticles that were characterized by a variety of analytical techniques. The melanin-derived nanoparticles displayed antibiofilm activity. This paper thus reports the synthesis of AgNPs by the biotechnologically important yeast Y. lipolytica; proposes a possible mechanism involved in the synthetic process and describes the use of the bio-inspired nanoparticles as antibiofilm agents.

“…Camembert, Livarot, Rokpol (Polish Roquefort)], yoghurts and sausages (for review, see Barth and Gaillardin, ; Fickers et al , ). Strains have also been isolated from various environments, such as lipid‐rich media (sewage, oil‐polluted media) or marine and hypersaline environments (Beopoulos et al , ; Thevenieau et al , ). Its ability to degrade proteins and lipids can be clearly visualized by the production of extracellular lipolytic and proteolytic activities, as shown in Figures A and B, respectively.…”

The yeast Yarrowia lipolytica presents specific physiological, metabolic and genomic characteristics, which differentiate it from the model yeast Saccharomyces cerevisiae. These properties have led several research groups to use this yeast as a model for basic knowledge. Thanks to the development of advanced genetic tools and -omic approaches, significant progress has been achieved in the understanding of specific biological processes. This review, after a short presentation of this model yeast, will briefly highlight the different use of Y. lipolytica for basic knowledge and the advantages gained by exploiting this non-conventional yeast. Future perspectives in employing this yeast for basic knowledge in the field of RNA splicing and genome evolution, and for the study of lipid metabolism, are also discussed.

“…Y. lipolytica is a fascinating non‐conventional yeast that can be often found in dairy products such as raw milk, yogurt, cheese and sausage . It not only enables to tolerate a fairly wide range of the environment from hypersaline concentration to a wide acidity range from pH 3 to 8 , but also enables to utilize the various substrates as sole carbon source from sugars, glycerols, alkanes, peptone, fatty acids to other types of lipids .…”

The non‐conventional oleaginous yeast Yarrowia lipolytica is able to utilize both hydrophilic and hydrophobic carbon sources as substrates and convert them into value‐added bioproducts such as organic acids, extracellular proteins, wax esters, long‐chain diacids, fatty acid ethyl esters, carotenoids and omega‐3 fatty acids. Metabolic pathway analysis and previous research results show that hydrophobic substrates are potentially more preferred by Y. lipolytica than hydrophilic substrates to make high‐value products at higher productivity, titer, rate, and yield. Hence, Y. lipolytica is becoming an efficient and promising biomanufacturing platform due to its capabilities in biosynthesis of extracellular lipases and directly converting the extracellular triacylglycerol oils and fats into high‐value products. It is believed that the cell size and morphology of the Y. lipolytica is related to the cell growth, nutrient uptake, and product formation. Dimorphic Y. lipolytica demonstrates the yeast‐to‐hypha transition in response to the extracellular environments and genetic background. Yeast‐to‐hyphal transition regulating genes, such as YlBEM1, YlMHY1 and YlZNC1 and so forth, have been identified to involve as major transcriptional factors that control morphology transition in Y. lipolytica. The connection of the cell polarization including cell cycle and the dimorphic transition with the cell size and morphology in Y. lipolytica adapting to new growth are reviewed and discussed. This review also summarizes the general and advanced genetic tools that are used to build a Y. lipolytica biomanufacturing platform.
