Published: June 2006

A dry extract of Stereum hirsutum exhibited a significant inhibitory activity on thrombin (34%). A bioassay oriented fractionation of the extract of Stereum hirsutum has led to the isolation of two active fractions. On the basis of spectroscopic data, chemical reactions, and GC-MS analysis, complex mixtures of diacylglycerophospholipids (DAGPs) and diacylglycerols (DGs) have been isolated and identified. Docking studies suggest that some isolated compounds could bind to the thrombin active site in a similar manner as previously reported phosphonate thrombin inhibitors.

Mushroom Jin Er has attracted widespread attention in Asia over the past two decades due to its medicinal properties and nutritional values. In the present study, Jin Er basidiocarps were often found to be surrounded by fruiting bodies in their natural habitat and occasionally in artificial cultivation. The observation of two different kinds of mycelia within the hymenium and analyses of ITS sequences confirmed that Jin Er basidiocarps were composed of two fungal species, and .

Article Synopsis
  • The study focused on the fungus Stereum hirsutum, leading to the extraction of 12 isopentenyl benzene derivatives, including six new compounds named stereuins A-F.
  • The structures of these compounds were confirmed using NMR and mass spectrometry, with stereuins A-C being benzoate derivatives that include fatty acid components.
  • Stereuin A showed potential for promoting nerve cell growth in vitro, while compounds D-F demonstrated antibacterial properties against Staphylococcus aureus, with stereuin F being nearly as effective as penicillin G.

Fungi are an alternative source to animal-based chitin. In fungi, chitin fibrils are strongly interconnected and bound with glucans that justify the unique matrix. The present study aimed to extract chitin and glucans from the mycelium of several wood decay fungal strains in order to obtain flexible materials and to check correlations between chitin content and the mechanical properties of these materials.

A robust environmental monitoring program is essential to properly estimate and identify microorganisms in cleanrooms, ensuring that microbial contamination remains acceptably low and that a good state of control is maintained in the manufacturing areas. The incubation conditions are important to support optimal microbial recoveries, considering that there is no single culture medium, temperature, and incubation time that can recover all microorganisms. In particular, molds are quite sensitive microorganisms, and some species may have very specific nutritional and environmental needs.

Romania has a long history of grapevine culturing and winemaking. However, like any agricultural sector, viticulture faces devastating biological threats. Fungi responsible for grapevine trunk diseases (GTDs) and grape spoilage lead to considerable yield losses and a decline in grapevine quality.
