Kluyveromyces aestuarii is a Kluyveromyces species of fungus occurring as a marine yeast. It was discovered in 1961 and was originally placed in the genus Saccharomyces . [1]
Upon discovery, the fungus was named Saccharomyces aestuarii. A 1965 evaluation of the genus Kluyveromyces placed the species within that genus, with the new name of Kluyveromyces aestuarii, based on the properties of its ascospore formation. [2]
Colonies of K. aestuarii have colorations ranging from white to deep ochre, due to the presence of the iron chelate pulcherrimin in the cells. [3] The cells are globose to ellipsoidal in shape when grown on Yeast-Mold (YM) agar, and range between roughly 2–6×3–7 µm in size. Pseudohyphae formation occurs after roughly two weeks of growth on corn meal agar. [3] K. aestuarii is not particularly thermotolerant, and cannot grow at or above 37 °C. [1] [3] It has the ability to ferment glucose, as well as sucrose and raffinose, but cannot ferment galactose, lactose, or maltose. [1]
Kluyveromyces aestuarii is a marine fungus. It was first isolated from shallow estuarine sediment in Biscayne Bay, off the coast of Florida. [1] It has also been discovered in the Torres Strait of Australia, [4] as well as in a mangrove forest near Rio de Janeiro, Brazil, where it was isolated from a shipworm (Neoteredo reynei), a clam ( Tagelus plebius), and two crab species ( Sesarma rectum and Uca spp.). [5] K. aestuarii has been identified as a possible indicator organism for environmental pollution of mangrove forests. [6]
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species.
Torulaspora delbrueckii is a ubiquitous yeast species with both wild and anthropic habitats. The type strain of T. delbrueckii is CBS 1146T, equivalent to CLIB 230 or ATCC 10662, etc.. The type strain of T. delbrueckii CBS 1146 T was sequenced in 2009, and is composed of 8 chromosomes in addition to a mitochondrial genome.
Kluyveromyces marxianus in ascomycetous yeast and member of the genus, Kluyveromyces. It is the sexual stage of Atelosaccharomyces pseudotropicalis also known as Candida kefyr. This species has a homothallic mating system and is often isolated from dairy products.
Kluyveromyces is a genus of ascomycetous yeasts in the family Saccharomycetaceae. Some of the species, such as K. marxianus, are the teleomorphs of Candida species.
Lachancea kluyveri is an ascomycetous yeast associated with fruit flies, slime fluxes, soils and foods.
Hanseniaspora guilliermondii is a species of yeast in the family Saccharomycetaceae. In its anamorph form, it is called Kloeckera apis.
Candida sharkiensis is a yeast species first found in the Florida Everglades.
Candida rhizophoriensis is a yeast species first found in the Florida Everglades.
Rhodotorula evergladiensis is a yeast species first found in the Florida Everglades.
Trichosporon asteroides is an asexual basidiomycetous fungus first described from human skin but now mainly isolated from blood and urine. T. asteroides is a hyphal fungus with a characteristically yeast-like appearance due to the presence of slimy arthroconidia. Infections by this species usually respond to treatment with azoles and amphotericin B.
Aspergillus asperescens is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 1954. It has been isolated from soil from a cave in England.
Lacinutrix jangbogonensis is a Gram-negative, strictly aerobic, rod-shaped, psychrophilic and non-motile bacterium from the genus of Lacinutrix which has been isolated from marine sediments from the Ross Sea.
Papiliotrema mangaliensis is a fungal species in the family Rhynchogastremataceae. The species was first found in its yeast state in the Florida Everglades.
Hanseniaspora occidentalis is a species of yeast in the family Saccharomycetaceae. In its anamorph form, it was called Kloeckera javanica. It has been isolated in the wild from soil samples and vineyards. Samples of a variant have been isolated from orange juice and rotten oranges. It has demonstrated potential as an organism to reduce malic acid in wine production.
Hanseniaspora osmophila is a species of yeast in the family Saccharomycetaceae. It is found in soil and among the bark, leaves, and fruits of plants, as well as fermented foods and beverages made from fruit.
Vanderwaltozyma polyspora is a species of multi-spored yeast fungus in the family Saccharomycetaceae found in soil, first described by Johannes P. van der Walt, and moved to a new genus by Cletus P. Kurtzman in 2003.
Vanderwaltozyma is a genus of ascomycetous yeasts in the family Saccharomycetaceae.
Kluyveromyces nonfermentans is a Kluyveromyces species occurring as a yeast. It was originally isolated from the deep sea, with various strains being isolated from sediment, a clam, and a crab. It is notable among the Kluyveromyces species as the only member unable to ferment glucose.
