Successful methods to control the damaging weed mold Chaetomium olivaceum (olive green mold) in mushroom beds are not known. An effective antibiotic (named chaetomacin) against C. olivaceum was isolated from a thermophilic Bacillus sp. This compound was shown to be an extremely potent and stable antibiotic, effective over a wide range of both pH (2 to 10) and temperature (-15 to 150 degrees C)....

The ability to induce an extracellular DNase from a novel thermophilic fungus was studied and the DNAse purified using both traditional and innovative purification techniques. The isolate produced sterile hyphae under all attempted growing conditions, with an average diameter of 2 µm and was found to have an optimal temperature of 45 °C and a maximum of 65 °C. Sequencing of the internal transcr...

Surgery is still the main treatment in hydatidosis caused by Echinococcus, which is a global health problem in human and animals. So, there is need for some natural protoscolicidal agents for instillation to prevent their reoccurrence at therapeutic doses. In this present investigation, anticestodal activity of one of the endophytic fungi Pestalotiopsis sp. from Neem plant was observed on proto...

Four novel compounds, chaephilone C (1), chaetoviridides A-C (2-4), were obtained from the culture of a deep sea derived fungus Chaetomium sp. NA-S01-R1, together with four known compounds-chaetoviridin A (5), chaetoviridine E (6), chaetomugilin D (7) and cochliodone A (8). Their structures, including absolute configurations, were assigned based on NMR, MS and time-dependent density functional ...

During a study of indoor fungi, 145 isolates belonging to Chaetomiaceae were cultured from air, swab and dust samples from 19 countries. Based on the phylogenetic analyses of DNA-directed RNA polymerase II second largest subunit (rpb2), β-tubulin (tub2), ITS and 28S large subunit (LSU) nrDNA sequences, together with morphological comparisons with related genera and species, 30 indoor taxa are r...

Fungi in drinking water are involved in the production of tastes and odours in water. Health problems are possible, originating from mycotoxins, animal pathogens and allergies. This report concerns the surveillance of mesophilic fungi in tap water and assessment of their potential for causing problems. The methods for the determination of the filamentous fungi (ff) were filtering, swabbing and ...

Grapevine Trunk Diseases (GTDs) are a major challenge to the grape industry worldwide. GTDs responsible for considerable loss of quality, production, and vineyard longevity. Seventy-five percent Chilean vineyards estimated be affected by GTDs. complex diseases caused several fungi species, including members Botryosphaeriaceae family Phaeomoniella chlamydospora , considered some most important c...

A bioassay method detecting deformations of mycelia germinated from conidia of Pyricularia oryzae P-2b, has been modified to give quantitative estimations. The method was first developed using antimitotic agents which showed characteristic curling effect. Morphological deformations include curling, swelling, hyper-divergency, beads shape and so on, and inhibition of the germination was also obs...
