Abstract
The number of yeast prions and prion-like proteins described since 1994 has grown from two to nearly twenty. If in the early years most scientists working with the classic mammalian prion, PrPSc, were skeptical about the possibility of using the term prion to refer to yeast cytoplasmic elements with unusual properties, it is now clear that prion-like phenomena are widespread and that yeast can serve as a convenient model for studying them. Here we give a brief overview of the yeast prions discovered so far and focus our attention to the various approaches used to identify them. The prospects for the discovery of new yeast prions are also discussed.

Genomic insights of beta-lactamase producing Klebsiella quasipneumoniae subsp. similipneumoniae belonging to sequence type 1699 from retail market fish, India. Arch Microbiol 2022; 204:454. [PMID: 35781844 DOI: 10.1007/s00203-022-03071-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 06/07/2022] [Accepted: 06/13/2022] [Indexed: 11/25/2022]
Abstract
Klebsiella quasipneumoniae is a recently described species and often misidentified as Klebsiella pneumoniae. Here, we report the genomic characterization of Klebsiella quasipneumoniae subsp. similipneumoniae (India238 strain) isolated from fish. The annotated genome acknowledged the presence of blaCTX-M-15, blaOKP-B-1, fosA5, oqxAB and virulence genes. The strain with ST1699 and serotypes KL52 and OL103 also harboured insertion sequences (ISs): ISKpn26 and ISEc9. Three complete phage genomes were identified in contigs 1 and 6 of the bacterial genome, enhancing the prospects of genome manipulation. The study highlights the pitfall of conventional microbiological identification methods to distinguish K. pneumoniae and K. quasipneumoniae. This is the first Indian study documenting the incidence of extended-spectrum beta-lactamase (ESBL)-producing K. quasipneumoniae subsp. similipneumoniae from a non-clinical environment, equipped with virulomes and associated mobile genetic elements. Given that fish can act as a potential vector for transmission of antimicrobial resistance genes, our findings have paramount importance on human health.

Abstract
In parallel with the development of non-Saccharomyces starter cultures in oenology, a growing interest has developed around the interactions between the microorganisms involved in the transformation of grape must into wine. Nowadays, it is widely accepted that the outcome of a fermentation process involving two or more inoculated yeast species will be different from the weighted average of the corresponding individual cultures. Interspecific interactions between wine yeasts take place on several levels, including interference competition, exploitation competition, exchange of metabolic intermediates, and others. Some interactions could be a simple consequence of each yeast running its own metabolic programme in a context where metabolic intermediates and end products from other yeasts are present. However, there are clear indications, in some cases, of specific recognition between interacting yeasts. In this article we discuss the mechanisms that may be involved in the communication between wine yeasts during alcoholic fermentation.

Abstract
Evolutionary history and early association with anthropogenic environments have made Saccharomyces cerevisiae the quintessential wine yeast. This species typically dominates any spontaneous wine fermentation and, until recently, virtually all commercially available wine starters belonged to this species. The Crabtree effect, and the ability to grow under fully anaerobic conditions, contribute decisively to their dominance in this environment. But not all strains of Saccharomyces cerevisiae are equally suitable as starter cultures. In this article, we review the physiological and genetic characteristics of S. cerevisiae wine strains, as well as the biotic and abiotic factors that have shaped them through evolution. Limited genetic diversity of this group of yeasts could be a constraint to solving the new challenges of oenology. However, research in this field has for many years been providing tools to increase this diversity, from genetic engineering and classical genetic tools to the inclusion of other yeast species in the catalogues of wine yeasts. On occasion, these less conventional species may contribute to the generation of interspecific hybrids with S. cerevisiae. Thus, our knowledge about wine strains of S. cerevisiae and other wine yeasts is constantly expanding. Over the last decades, wine yeast research has been a pillar for the modernisation of oenology, and we can be confident that yeast biotechnology will keep contributing to solving any challenges, such as climate change, that we may face in the future.

Yeast prion-based metabolic reprogramming induced by bacteria in fermented foods. FEMS Yeast Res 2019; 19:5553466.

Abstract
ABSTRACT
Microbial communities of yeast and bacterial cells are often observed in the manufacturing processes of fermented foods and drinks, such as sourdough bread, cheese, kefir, wine and sake. Community interactions and dynamics among microorganisms, as well as their significance during the manufacturing processes, are central issues in modern food microbiology. Recent studies demonstrated that the emergence of a yeast prion termed [GAR+] in Saccharomyces cerevisiae is induced by coculturing with bacterial cells, resulting in the switching of the carbon metabolism. In order to facilitate mutualistic symbiosis among microorganisms, this mode of microbial interaction is induced between yeasts and lactic acid bacteria species used in traditional sake making. Thus, yeast prions have attracted much attention as novel platforms that govern the metabolic adaptation of cross-kingdom ecosystems. Our minireview focuses on the plausible linkage between fermented-food microbial communication and yeast prion-mediated metabolic reprogramming.
