abstract = {Surveying the fungi of alkaline soils in Siberia, Trans-Baikal regions (Russia), the Aral lake (Kazakhstan),
and Eastern Mongolia, we report an abundance of alkalitolerant species representing the
Emericellopsis
-clade
within the
Acremonium
cluster of fungi (order
Hypocreales
). On an alkaline medium (pH
ca
. 10), 34 acremonium-like
fungal strains were obtained. One of these was able to develop a sexual morph and was shown to be a new member
of the genus
Emericellopsis
, described here as
E. alkalina
sp. nov. Previous studies showed two distinct ecological
clades within
Emericellopsis
, one consisting of terrestrial isolates and one predominantly marine. Remarkably, all
the isolates from our study sites show high phylogenetic similarity based on six loci (LSU and SSU rDNA, RPB2,
TEF1-?, ?-tub and ITS region), regardless of their provenance within a broad geographical distribution. They group
within the known marine-origin species, a finding that provides a possible link to the evolution of the alkaliphilic trait
in the
Emericellopsis
lineage. We tested the capacities of all newly isolated strains, and the few available reference
ex-type cultures, to grow over wide pH ranges. The growth performance varied among the tested isolates, which
showed differences in growth rate as well as in pH preference. Whereas every newly isolated strain from soda soils
was extremely alkalitolerant and displayed the ability to grow over a wide range of ambient pH (range 4?11.2),
reference marine-borne and terrestrial strains showed moderate and no alkalitolerance, respectively. The growth
pattern of the alkalitolerant
Emericellopsis
isolates was unlike that of the recently described and taxonomically
unrelated alkaliphilic
Sodiomyces alkalinus,
obtained from the same type of soils but which showed a narrower
preference towards high pH.}
