Apiotrichum terrigenum sp. nov., a soil-associated yeast found in both the UK and mainland Europe

Abstract

Five arthroconidium-producing yeast strains representing a novel Trichosporon-like species were independently isolated from the UK, Hungary and Norway. Two strains (Bio4T and Bio21) were isolated from biogas reactors used for processing grass silage, with a third strain (S8) was isolated from soil collected at the same UK site. Two additional strains were isolated in mainland Europe, one from soil in Norway (NCAIM Y.02175) and the other from sewage in Hungary (NCAIM Y.02176). Sequence analyses of the D1/D2 domains of the LSU rRNA gene and internal transcribed spacer (ITS) region indicated that the novel species belongs to the recently reinstated genus Apiotrichum and is most closely related to Apiotrichum scarabaeorum, a beetle-associated species first found in South Africa. Despite having similar physiological characteristics, the two species can be readily distinguished from one another by ITS sequencing. The species name Apiotrichum terrigenum sp. nov. is proposed to accommodate these strains, with Bio4T (=CBS 11373T=NCYC 3540T) designated as the type strain. The Mycobank deposit number is MB817431.

Identification of fungi in shotgun metagenomics datasets

“…A . montevideense is one of the causative agents of summer-type hypersensitivity pneumonitis [ 55 ], and was identified in a different unknown vertebrate microbiome ( Table 3 ). Apiotrichum domesticum , which causes the same disease [ 55 ], was identified in three mouse microbiomes ( Table 3 ).…”

Apiotrichum domesticum , which causes the same disease [ 55 ], was identified in three mouse microbiomes ( Table 3 ). FindFungi did not identify animal reservoirs for other significant human fungal pathogens such as Cryptococcus neoformans , Pneumocystis jirovecii , Coccidioides immitis , Histoplasma capsulatum , or Trichophyton rubrum .…”

Unconventional Cell Division Cycles from Marine-Derived Yeasts

“…These included the three black yeasts highlighted in this paper, H. werneckii, K. petricola, and A. pullulans. Two additional species were Apiotrichum dulcitum and A. porosum, which have only been recorded in terrestrial environments [95,96]. Both Apiotrichum species were isolated only from coastal sediment (legend continued on next page)…”

Effects of Tree Composition and Soil Depth on Structure and Functionality of Belowground Microbial Communities in Temperate European Forests

“…Concerning fungi, interestingly, our RF revealed that free-living unicellular fungi were indicators of evergreen forest plots. Yeasts like Solicoccozyma, Apiotrichum , and unclassified Saccharomycetales are commonly isolated from forest soils (Liu et al, 2015 ; Yurkov et al, 2015 ; James et al, 2016 ; Mašínová et al, 2016 ). However, our results showed their clear niche preference for the evergreen forests.…”
