The interaction between endophytic biocontrol agent Chaetomium spirale ND35 and the soil-borne plant pathogen Rhizoctonia solani was studied by light microscopy and transmission electron microscopy (TEM), as well as further investigated by gold cytochemistry to assess the potential role of cell wall degrading enzymes (CWDEs) during the mycoparasitic process. Macroscopic observations of fungal g...

Exposure of the fungus Chaetomium cancroideum to an NAD(+)-dependent HDAC inhibitor, nicotinamide, enhanced the production of aromatic and branched aliphatic polyketides, which allowed us to isolate new secondary metabolites, chaetophenol G and cancrolides A and B. Their structures were determined using spectroscopic analyses, and their absolute configuration was elucidated by electronic circul...

The multisubunit eukaryotic translation initiation factor 3, among which the subunit b (eIF3b) is a major scaffold protein, plays essential roles in protein synthesis. Here, we report the crystal structure of the WD40 domain of Chaetomium thermophilum eIF3b, revealing a nine-bladed β-propeller fold. Sequence analysis indicates that this propeller architecture is common to all eIF3b orthologs. R...

The application of a simple system for measuring the oxygen uptake rate (OUR) to determine the activity of pellet-forming fungi is described. A non-invasive easy-to-use respirometric system was used to measure the OUR as an activity parameter. The model sensor system was optimized in shake flask experiments with Pleurotus sapidus (DSMZ 8266) and Chaetomium globosum (DSMZ 1962). The toxicity of ...

40 This study represents both a study case about the fungal microflora deteriorating historical textiles in the Egyptian Museum and the Coptic Museum in Cairo, and evaluation of the efficacy of several combinations of consolidants for reinforcement of textiles and fungicides for prevention of fungal deterioration. Two different methods were used for isolation of fungi from historical textile ob...

Three new records of Ascomycota species (Chaetomium acropullum, Phialemonium globosum, Phialemonium atrogriseum) from field soils in Korea are presented in this study. These newly discovered fungal isolates were isolated from field soils from various places across Gyeongnam, Korea in 2016. All the isolates were identified and described based on morphological characteristics, and rDNA internal t...
