Carbon chain length of biofuel- and flavor-relevant volatile organic compounds produced by lignocellulolytic fungal endophytes changes with culture temperature
Publication date: Available online 18 May 2017 Source:Mycoscience Author(s): Heidi R. Schoen, Kristopher A. Hunt, Gary A. Strobel, Brent M. Peyton, Ross P. Carlson Three fungal endophytes from the genus Nodulisporium were studied for volatile organic compound (VOC) production. All three fungi grew on a wide range of carbon substrates ranging from simple sugars to waste biomass sources. The fungi synthesized a number of long and short-chain VOCs, including eucalyptol; 1-butanol, 3-methyl; 1-octen-3-ol; and benzaldehyde, all with potential applications as biofuel or flavor compounds. As culture temperature decreased, ...

Breeding of a non-urea-producing sake yeast carrying a FAS2 mutation
Publication date: Available online 17 May 2017 Source:Mycoscience Author(s): Takashi Kuribayashi, Keigo Sato, Toshio Joh, Mitsuoki Kaneoke We isolated non-urea-producing sake yeasts from a FAS2-G3748A (G1250S) mutant using established positive-screening medium (containing canavanine, arginine and ornithine; CAO medium) after selection of FAS2 mutants with cerulenin. Varying levels of ethyl caproate production were observed due to spontaneous allelic recombination of the FAS2 heterozygotes on the CAO medium. The resulting double mutants exhibited favorable fermentation properties for sake brewing. (Source: Mycoscience)

Phylogenetic position of Pseudohypocrea (Hypocreales)
Publication date: Available online 15 May 2017 Source:Mycoscience Author(s): Zhao-Qing Zeng, Wen-Ying Zhuang Based on morphological characteristics, a hypocrea-like collection from Hunan Province was found to be identical with Pseudohypocrea hongkongensis, which was originally reported only from Hong Kong, China. A living culture of the fungus was obtained from fresh ascomata, and its asexual morph is described for the first time. The gross morphology and anatomic structure of the fungus and the type species of Pseudohypocrea were compared in detail. Their phylogenetic positions were explored based on sequence analyses...

Hyphodontia mollissima sp. nov. (Schizoporaceae, Hymenochaetales) from Hainan, southern China
Publication date: Available online 13 May 2017 Source:Mycoscience Author(s): Yu-He Kan, Wen-Min Qin, Li-Wei Zhou Hyphodontia mollissima is described from Hainan Province, southern China, as a new species. This species is characterized by resupinate, soft corky basidiocarps, poroid hymenophores, a pseudodimitic hyphal system with clamped generative hyphae, presence of both bladder-like and apically encrusted cystidia, and broadly ellipsoid, colorless, thin-walled, smooth basidiospores. Morphologically, H. mollissima except for poroid hymenophores, fits the concept of Palifer. A potential member of Palifer, Hyphodontia ...

Corticolous myxomycetes assemblages in a seasonally dry tropical forest in Brazil
Publication date: Available online 13 May 2017 Source:Mycoscience Author(s): Aline B.M. Vaz, Daniela S. dos Santos, Domingos Cardoso, Cássio van den Berg, Luciano P. de Queiroz, Fernanda Badotti, Paula L.C. Fonseca, Laíse H. Cavalcanti, Aristóteles Góes-Neto Corticolous myxomycetes are a distinct ecological group consisting of species typically associated with the outer bark surface of living trees. The current study aimed to characterize the community structure of corticolous myxomycetes and their associated trees, analyzing the influence of geographic distance, bark pH, and tree diameter on myxomycete asse...
