Bandoniozyma noutii

Bandoniozyma noutii Boekhout, Fell, Scorzetti & Theelen 2012, in Valente et al., PLoS ONE 7(10): e46060 (2012).

Etymology: The specific epithet noutii refers to Robert (Rob) Nout, investigator of traditionally fermented foods from South America, Africa and Asia.

Diagnosis: After growth for 7 days in 2% glucose medium at 25oC, a sediment and film are formed. Cells are ovoid, subglobose to globose, 46×45 µm, usually with polar budding but also with multilateral budding, with buds that may adhere into short chains (Figure 2a). Pseudohyphae are present and fall apart in filaments that measure 2850(-70)×24 µm, and eventually become somewhat thick-walled, irregularly broadened or somewhat broadened on one side. After 5 days on 5% malt extract agar at 25oC, colonies are 10 mm in diameter, convex, grayish cream-beige, shiny, strongly mucoid, smooth, and with an entire margin that may form sectors. Cells measure 3.37.8×37 µm. Under a cover glass filaments and hyphae occur with cells measuring 840×22.5 µm. On Dalmau plate on yeast morphology agar, pseudohyphae occur with cells measuring 840×22.5 µm. Sexual reproduction is absent. Mixing the three available strains on potato dextrose agar, oat meal agar, corn meal agar, malt extract agar, glucose-yeast extract agar, and yeast extract malt extract agar did not show any indication of a mating reaction.

Figure 1. ITS tree showing the phylogenetic relationship among the Tremellomycetes, with emphasis on the Bandoniozyma clade, obtained by neighbor-joining analysis using Mega 5.0. Most species belong to the order Tremellales, with the exception of Cystofilobasidium capitatum (Cystofilobasidiales), Cryptococcus albidus (Filobasidiales), Trichosporum cutaneum (Trichosporonales), and the outgroup Farysizyma itapuensis (Ustilaginales). The numbers given on the branches are the frequencies with which a given branch appeared in 10,000 bootstrap replications. Bar, substitutions per nucleotide position.
