Glutathione Reductase/Glutathione Is Responsible for Cytotoxic Elemental Sulfur Tolerance via Polysulfide Shuttle in Fungi*
TLDR
Findings that GR-deficient mutants derived from Saccharomyces cerevisiae and Aspergillus nidulans reduced less sulfur and that their growth was hypersensitive to elemental sulfur indicated a wide distribution of the GR/glutathione system among fungi.

Enzymatic hydrolyzing performance of Acremonium cellulolyticus and Trichoderma reesei against three lignocellulosic materials
TLDR
The hydrolysis of lignocellulosic materials by cellulase derived from two types of filamentous fungi is investigated and it is found that glucan-hydrolyzing activity of the culture supernatant from A. cellulolyticus was superior to that from T. reesei.

Mechanism of De Novo Branched-Chain Amino Acid Synthesis as an Alternative Electron Sink in Hypoxic Aspergillus nidulans Cells
TLDR
The results indicated that the fungus responds to hypoxia by synthesizing branched-chain amino acids via a de novo mechanism that functions in the absence of glucose-to-ethanol/lactate fermentation and oxygen respiration.

Quorum Sensing Regulates Denitrification in Pseudomonas aeruginosa PAO1
ABSTRACT Anaerobic growth of Pseudomonas aeruginosa PAO1 was affected by quorum sensing. Deletion of genes that produce N-acyl-l-homoserine lactone signals resulted in an increase in denitrification…

Proteomic analysis of Aspergillus nidulans cultured under hypoxic conditions
TLDR
Levels of xanthine and hypoxanthine, deamination products of guanine and adenine were increased in DNA from hypoxic cells, indicating an association between hypoxia and intracellular DNA base damage, and the mechanism of fungal energy conservation is altered under hypoxic conditions.

Global gene expression analysis of Aspergillus nidulans reveals metabolic shift and transcription suppression under hypoxia
TLDR
This study is the first to show that hypoxia elicits systematic transcriptional responses in Aspergillus nidulans, and down-regulated some genes involved in transcription initiation by RNA polymerase II, and lowered the cellular mRNA content.

Conserved and specific responses to hypoxia in Aspergillus oryzae and Aspergillus nidulans determined by comparative transcriptomics
TLDR
A comparative transcriptomic analysis discovered common and strain-specific responses to hypoxia in hypoxic Aspergillus species, indicating that both fungi eliminate NADH accumulation under hypoxic conditions.

Taxonomic revision of the cellulose-degrading fungus Acremonium cellulolyticus nomen nudum to Talaromyces based on phylogenetic analysis.
TLDR
Morphological and phenotypic differences between these strains in colony color, conidiophore formation, and cellulase productivity were observed and indicated that strain Y-94 belonged to the genus Talaromyces, which is proposed as a new species on the basis of morphology and molecular evidence.

Enhancement of β-xylosidase productivity in cellulase producing fungus Acremonium cellulolyticus
TLDR
Since YKX1 can produce larger amount of β-xylosidase without affecting cellulase productivity, it is considered to be beneficial for practical monosaccharide recoveries from lignocellulosic biomass.
