200 years of taxonomic confusion: Sporendonema and alliesNARA Subscribed
The genus Sporendonema ( Gymnoascaceae , Onygenales ) was introduced in 1827 with the type species S . casei for a red mould on cheese. Cheese is a consistent niche for this species. Sphaerosporium equinum is another species classified in Gymnoascaceae and has also been reported from cheese. Recently, other habitats have been reported for both Sporendonema casei and Sphaerosporium equinum . The present study aimed to investiga...
More than 20 years after remedial measures were carried out, six plots (Š1 – Š6) at the Šobov locality were examined in more detail. From a pedological viewpoint, the physico-chemical differences of the soils in these areas are not the result of pedogenesis. This is the effect of extremely acidic mineralised solutions that have leaked from or are still leaking from the heap at the site. The plant community here is most often p...
Polaramycin B, and not physical interaction, is the signal that rewires fungal metabolism in the Streptomyces–Aspergillus interactionNARA Subscribed
Co‐culturing the bacterium Streptomyces rapamycinicus and the ascomycete Aspergillus nidulans has previously been shown to trigger the production of orsellinic acid (ORS) and its derivates in the fungal cells. Based on these studies it was assumed that direct physical contact is a prerequisite for the metabolic reaction that involves a fungal amino acid starvation response and activating chromatin modifications at the biosynth...
Fungi and mycotoxins in silage can have detrimental consequences for both cattle and human health. This pilot study identified, via the routinary direct plating method, the dominant cultivable fungi in mouldy grass silages (GS) ( n = 19) and maize silages (MS) ( n = 28) from Austria. The profiles of regulated, modified, and emerging mycotoxins together with other fungal metabolites were analysed via LC-(ESI)MS/MS. Penicillium...
