Its capacity to produce compounds such as food additives, supplements, and organic acids, among other fine chemicals, has turned it into an attractive microorganism in the biotechnology field. In this review, we performed a robust phylogenetic analysis using the core proteome of C. jadinii and other fungal species, from Asco- to Basidiomycota, to elucidate the evolutionary roots of this species. In addition, we report the evolution of this species nomenclature over-time and the existence of a teleomorph (C. jadinii) and anamorph state (Candida utilis) and summarize the current nomenclature of most common strains. Finally, we highlight relevant traits of its physiology, the solute membrane transporters so far characterized, as well as the molecular tools currently available for its genomic manipulation.

  • Saccharomyces Eubayanus, the Missing Link to Lager Beer Yeasts
    MICROBE PROFILE Sampaio, Microbiology 2018;164:1069–1071 DOI 10.1099/mic.0.000677 Microbe Profile: Saccharomyces eubayanus, the missing link to lager beer yeasts Jose Paulo Sampaio* Graphical abstract Ecology and phylogeny of Saccharomyces eubayanus. (a) The ecological niche of S. eubayanus in the Southern Hemisphere – Nothofagus spp. (southern beech) and sugar-rich fructifications (stromata) of its fungal biotrophic parasite Cyttaria spp., that can attain the size of golf balls. (b) Schematic representation of the phylogenetic position of S. eubayanus within the genus Saccharomyces based on whole-genome sequences. Occurrence in natural environments (wild) or participation in different human-driven fermentations is highlighted, together with the thermotolerant or cold-tolerant nature of each species and the origins of S. pastorianus, the lager beer hybrid. Abstract Saccharomyces eubayanus was described less than 10 years ago and its discovery settled the long-lasting debate on the origins of the cold-tolerant yeast responsible for lager beer fermentation. The largest share of the genetic diversity of S. eubayanus is located in South America, and strains of this species have not yet been found in Europe. One or more hybridization events between S. eubayanus and S. cerevisiae ale beer strains gave rise to S. pastorianus, the allopolyploid yeasts responsible for lager beer production worldwide. The identification of the missing progenitor of lager yeast opened new avenues for brewing yeast research. It allowed not only the selective breeding of new lager strains, but revealed also a wild yeast with interesting brewing abilities so that a beer solely fermented by S. eubayanus is currently on the market.

  • Candida Albicans from Wikipedia, the Free Encyclopedia
    Candida albicans From Wikipedia, the free encyclopedia Candida albicans is a type of yeast that is a common member of the human gut flora. It does not proliferate outside the human body.[4] It is Candida albicans detected in the gastrointestinal tract and mouth in 40-60% of healthy adults.[5][6] It is usually a commensal organism, but can become pathogenic in immunocompromised individuals under a variety of conditions.[6][7] It is one of the few species of the Candida genus that causes the human infection candidiasis, which results from an overgrowth of the fungus.[6][7] Candidiasis is for example often observed in HIV-infected patients.[8] C. albicans is the most common fungal species isolated from biofilms either formed on (permanent) implanted medical devices or on human Candida albicans visualised using [9][10] tissue. C. albicans, together with C. tropicalis, C. parapsilosis scanning electron microscopy. Note the and C. glabrata, is responsible for 50–90% of all cases of candidiasis in abundant hypal mass. humans.[7][11][12] A mortality rate of 40% has been reported for patients with systemic candidiasis due to C. albicans.[13] Estimates Scientific classification range from 2800 to 11200 deaths caused annually in the USA due to C. Kingdom: Fungi albicans causes candidiasis.[14] Division: Ascomycota C. albicans is commonly used as a model organism for biology. It is generally referred to as a dimorphic fungus since it grows both as yeast Class: Saccharomycetes and filamentous cells.

In a 3-day culture, it shows spherical to ellipsoidal morphology appearing in single, paired cells or short clusters. It is a teleomorph yeast with 1–4 spherical ascospores and it is characterized by a low production of volatile acidity that helps to control global acetic acid levels in mixed or sequential inoculations with either S. cerevisiae or other non-Saccharomyces species. It has a medium fermentative power, so it must be used in sequential or mixed inoculations with S. cerevisiae to get dry wines. It shows a high production of lactic acid able to affect strongly wine pH, sometimes decreasing wine pH by 0.5 units or more during fermentation. Most of the acidification is produced at the beginning of fermentation facilitating the effect in sequential fermentations because it is more competitive at low alcoholic degree.

    Lind and Pollard Microbiome (2021) 9:58 https://doi.org/10.1186/s40168-021-01015-y METHODOLOGY Open Access Accurate and sensitive detection of microbial eukaryotes from whole metagenome shotgun sequencing Abigail L. Lind1 and Katherine S. Pollard1,2,3,4,5* Abstract Background: Microbial eukaryotes are found alongside bacteria and archaea in natural microbial systems, including host-associated microbiomes. While microbial eukaryotes are critical to these communities, they are challenging to study with shotgun sequencing techniques and are therefore often excluded. Results: Here, we present EukDetect, a bioinformatics method to identify eukaryotes in shotgun metagenomic sequencing data. Our approach uses a database of 521,824 universal marker genes from 241 conserved gene families, which we curated from 3713 fungal, protist, non-vertebrate metazoan, and non-streptophyte archaeplastida genomes and transcriptomes. EukDetect has a broad taxonomic coverage of microbial eukaryotes, performs well on low-abundance and closely related species, and is resilient against bacterial contamination in eukaryotic genomes. Using EukDetect, we describe the spatial distribution of eukaryotes along the human gastrointestinal tract, showing that fungi and protists are present in the lumen and mucosa throughout the large intestine. We discover that there is a succession of eukaryotes that colonize the human gut during the first years of life, mirroring patterns of developmental succession observed in gut bacteria. By comparing DNA and RNA sequencing of paired samples from human stool, we find that many eukaryotes continue active transcription after passage through the gut, though some do not, suggesting they are dormant or nonviable. We analyze metagenomic data from the Baltic Sea and find that eukaryotes differ across locations and salinity gradients.

We concentrate here on five species of Saccharomycetaceae, a large subdivision of hemiascomycetes, that we call “protoploid” because they diverged from the S. cerevisiae lineage prior to its genome duplication. We determined the complete genome sequences of three of these species, Kluyveromyces (Lachancea) thermotolerans and Saccharomyces (Lachancea) kluyveri (two members of the newly described Lachancea clade) and Zygosaccharomyces rouxii. We included in our comparisons the previously available sequences of Klyveromyces lactis and Ashbya (Eremothecium) gossypii. Despite their broad evolutionary range and significant individual variations in each lineage, the five protoploid Saccharomycetaceae share a core repertoire of ca.
