Spathaspora cesarfonsecae sp. nov., a xylose-fermenting yeast isolated from gut of passalid beetles and rotting wood in the Amazonian rainforest biome.
Two yeast isolates of a novel d-xylose-fermenting species were obtained from rotting wood and gut of a passalid beetle collected in the Brazilian Amazonian Rainforest biome. Sequence analysis of the internal transcribed spacer-5.8S region and the D1/D2 domains of the LSU rRNA gene showed that the isolates represent a novel species of the genus Spathaspora, phylogenetically related to Spathaspora passalidarum. The yeast produced asci with a single malformed elongated ascospore with curved ends. The name Spathaspora cesarfonsecae sp. nov. is proposed to accommodate the novel species. The holotype of Sp. cesarfonsecae is CBS 14235 (MycoBank MB859328). Notably, Sp. cesarfonsecae demonstrated the ability to produce ethanol and xylitol from d-xylose, a biotechnologically valuable trait.
期刊介绍：
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
