sp. nov., a novel cellulase-producing black yeast-like fungi isolated from ginger in India No Access

Abstract

The genus , known for its melanized, yeast-like appearance, includes a diverse group of fungi with significant implications across various fields. An isolate representing a novel species was identified within this genus from a ginger tuber from India, based on morphological characteristics and molecular phylogenetic analysis. Phylogenetic analysis of the D1/D2 domain of the 26S LSU rRNA gene, SSU rRNA gene and the internal transcribed spacer (ITS) region confirmed this strain as a new species. It was named sp. nov. (MycoBank no. MB 855415), with MCC 9960 designated as the holotype and PYCC 9834 as the isotype. was positioned as a sister species to a clade that includes , and three additional species. Phylogenetic analysis indicates that while shares a common ancestor with these species, it is genetically distinct, underscoring its novel status. The type strain of this novel species differs from YMF1.07354, the most closely related species, by 19 nucleotide substitutions (3.6% sequence variation) in the D1/D2 region (549 bp compared) and 104 nucleotide substitutions and 44 gaps (27.1% sequence variation) in the ITS region (546 bp compared).
