Abstract

Two novel yeast species were isolated from the guts of two different termite species. A new member of the genus was isolated from the hindgut and nest material of the lower Australian termite . The second novel yeast species, isolated from the higher termite , was identified as a member of the genus . Both yeast species were able to hydrolyse xylan, methylumbelliferyl β-xylobiose and methylumbelliferyl β-xylotriose. The ability to debranch different hemicellulose side chains and growth without the addition of external vitamins was observed. A symbiotic role of the novel yeast species is indicated, especially in respect to xylan degradation and the production of vitamins. Here, we describe these species as sp. nov., MycoBank 816574 (type strain MD39V=DSM 100793=CBS 14182), and f.a., sp. nov., MycoBank 816575 (type strain OO5=DSM 100791=CBS 14181). Additionally, we transfer to the genus and propose the following combination: f.a., comb. nov., MycoBank 816576.
