Candida thermophila sp. nov., a novel thermophilic yeast isolated from soil.

Cryptococcus tepidarius sp. nov., a thermotolerant yeast species isolated from a stream from a hot-spring area in Japan

“…At 54.9 and 60 u C, no increase in OD 660 was detected after 700 h of incubation. Many ascomycetous yeasts can grow at 40 u C (Barnett et al, 2000) and Ogataea thermophila, reported to grow at 50 u C (Shin et al, 2001;Péter et al 2007), has the highest maximum growth temperature known to date. In the basidiomycetous yeasts, some pathogenic yeasts such as Filobasidiella neoformans are capable of growth at 40 u C. Nagahama et al (2003) reported that the maximum growth temperature of Rhodotorula benthica and Rhodotorula calyptogenae, isolated from a deep-sea habitat, was 41-44 u C, but neither grew at 45 u C. We therefore conclude that Cryptococcus tepidarius has the highest maximum growth temperature reported so far for a basidiomycetous yeast.…”

Ogataea chonburiensis sp. nov. and Ogataea nakhonphanomensis sp. nov., thermotolerant, methylotrophic yeast species isolated in Thailand, and transfer of Pichia siamensis and Pichia thermomethanolica to the genus Ogataea

“…Although most known methylotrophic yeasts are mesophiles, some are able to grow above 37 u C (Kurtzman & Fell, 1998;Barnett et al, 2000) and could therefore be either thermophilic or thermotolerant, e.g. Pichia angusta (Ogataea polymorpha), Ogataea henricii (Kurtzman, 1998), Candida methanosorbosa, Candida soronensis (Meyer et al, 1998), Candida thermophila (Shin et al, 2001), Ogataea falcaomoraisii (Morais et al, 2004), Pichia siamensis, Candida krabiensis, Candida sithepensis (Limtong et al, 2004) and Pichia thermomethanolica (Limtong et al, 2005).…”

Ogataea paradorogensis sp. nov., a novel methylotrophic ascomycetous yeast species isolated from galleries of ambrosia beetles in Japan, with a close relation to Pichia dorogensis

“…Suh et al (2006) accepted the genus Ogataea as a currently recognized genus in their study on the phylogenetics of Saccharomycetales. Péter et al (2007a) described a methylotrophic yeast Ogataea thermophila as the teleomorph of Candida thermophila (Shin et al, 2001). Limtong et al (2008) reported two novel methylotrophic species, Ogataea chonburiensis and Ogataea nakhonphanomensis, and proposed to transfer two methylotrophic species, Pichia siamensis and Pichia thermomethanolica, to the genus Ogataea.…”
