“…How might members of the European S. paradoxus population come to be on trees 19 000 km away? There are clearly many possibilities, but a very recent study by Isaeva et al (2009) reports that Candida railenensis (which is in the Class Saccharomycetes) is associated with acorns of Q. robur. Thus, it is feasible that S. paradoxus was present on/in acorns brought here by migrants, possibly from Europe.…”

Saccharomyces cerevisiae and Saccharomyces paradoxus are used as model systems for molecular, cell and evolutionary biology; yet we know comparatively little of their ecology. One niche from which these species have been isolated is oak bark. There are no reports of these species from oak in the Southern Hemisphere. We describe the recovery of both S. cerevisiae and S. paradoxus from oak in New Zealand (NZ), and provide evidence for introgression between the species. Genetic inference shows that the oak S. cerevisiae are closely related to strains isolated from NZ and Australian vineyards, but that the S. paradoxus strains are very closely related to European isolates. This discovery is surprising as the current model of S. paradoxus biogeography suggests that global dispersal is rare. We test one idea to explain how members of the European S. paradoxus population might come to be in NZ: they were transported here along with acorns brought by migrants approximately 200 years ago. We show that S. paradoxus is associated with acorns and thus provide a potential mechanism for the unwitting global dispersal of S. paradoxus by humans.

“…railenensis isolates was identical but we managed to designate the isolates to C. railenensis due to two base pair differences within the ITS region by multiple alignments to the type strains of C. oleophila and C. ralienensis. C. railenensis has been isolated in the acorns of English oak [27]. As for C. oleophila and C. railenensis, separation between C. saitoana/C.…”

Sawdust can be used to make pellets (biofuel) and particle boards and as a potential lignocellulose feedstock in bioethanol production. Microbial activity can affect sawdust quality; hence, we monitored the microbial population in birch- and spruce sawdust after 3 months' storage at various temperatures. Species composition was similar on both materials but was strongly influenced by temperature. Bacteria were present on all materials at all conditions: on birch, 2.8 × 10(8) , 1.1 × 10(8) , and 8.8 × 10(6) , and on spruce, 4.1 × 10(8) , 5.6 × 10(7) , and 1.5 × 10(8) CFU/g DM, at 2, 20, and 37 °C, respectively. Dominant bacteria at 2, 20, and 37 °C were Pseudomonas spp. (some Enterobacteriaceae spp. present), Luteibacter rhizovicinus, and Fulvimonas sp., respectively. Pseudomonas spp. were absent at ≥20 °C. Among microfungi, yeasts dominated at 2 °C but were absent at 37 °C, whereas molds dominated at 20 and 37 °C. Common yeasts included Cystofilobasidium capitatum, Cystofilobasidium infirmominiatum, Candida saitoana, Candida oregonensis, and Candida railenensis. Ophiostoma quercus was a common mold at 2 and 20 °C, whereas the human pathogens Aspergillus fumigatus and Paecilomyces variotii dominated at 37 °C. Attempts to influence the microflora by addition of the biocontrol yeasts, Wickerhamomyces anomalus and Scheffersomyces stipitis, were unsuccessful, as their growth in sawdust was poor to absent.

“…Consequently, inner plant tissues could be even more promising habitats for detection of the yeasts with rare nutritional abilities, including the assimilation of methanol. Indeed, endophytous yeast communities have been reported recently to be significantly distinct from those formed on plant surfaces (Isaeva et al 2009). Abnormal growths formed from plant tissues and due to parasitic activity of another organism, known as galls (Redfern and Shirley 2002) are annually observed on leaves of deciduous plants.…”

Ten strains of a new endophytic ascospore-forming, methanol-assimilating yeast were isolated from the galls induced by sawflies on the leaves of willows in the Losiny Ostrov National Park (Moscow region). Standard phenotypical tests and phylogenetic analyses of 18S rRNA gene, 5.8S-ITS gene region and 26S rRNA gene (D1/D2 domains) sequences showed that the species belongs to the genus Ogataea. We describe it as Ogataea cecidiorum and designate type culture KBP Y-3846 (= CBS 11522(T) = VKM Y-2982(T) = VKPM Y-3482(T) = MUCL 52544(T) = NCAIM Y.01965(T)) as the type strain. The new species was registered in MycoBank under MB 515233.
