The isolation, structural elucidation and biological activities of oligosporon (1), oligosporol A (2) and oligosporol B (3), three new antibiotics from cultures of the predacious deuteromycete, Arthrobotrys oligospora, are reported. The structures were elucidated by means of high resolution mass and high field N M R spectroscopy. The compounds exhibited weak antimicro bial, cytotoxic and hemol...
The first report, to our knowledge, on the occurrence of filamentous fungi in the hypersaline (340 g salt l-1) Dead Sea is presented. Three species of filamentous fungi from surface water samples of the Dead Sea were isolated: Gymnascella marismortui (Ascomycota), which is described as a new species, Ulocladium chlamydosporum and Penicillium westlingii (Deuteromycota). G. marismortui and U. chl...
The Cordyceps genus includes many species of fungi, most of which are endoparasitoids on arthropods.The distribution of these fungi is cosmopolitan, but many occur in regions such as Asia with a hot, humid climate. These pathogens of insect pests are promising candidates for use as biological control factors. Entomopathogenic fungi including the famous Cordyceps sinensis produce bioactive compo...
Since 1869 when RAULIN reported that Aspergilluts niger excreted some growth-promoting substances into its medium, a number of investigators have studied the phenomenon of auxithal synthesis by fungi. For a comprehensive review of this the reader is referred to FRIES (2) and SCHLENKER (7). The writers (5) have referred briefly to this subject; the present paper reports a more exhaustive study. ...
A range of fungi occur in the mangrove ecosystem although these differ as to their location and some fungi occur more frequently than others. In a study dealing with the frequency of occurrence of manglicolous fungi on Avicennia and Bruguiera from a mangrove habitat of Kerala, South India, 32 manglicolous marine fungi belonging to 23 ascomycetes, 1 basidiomycete and 8 mitosporic fungi were obta...
The authors carried out a time-series study to determine whether short-term increases in the concentrations of spores were associated with emergency department visits from asthma among children 0 to 9 years of age in Montreal, 1994-2004. Concentrations of spores were obtained from one sampling monitor. The authors used parametric Poisson models to model the association between daily admissions ...
Mangrove ecosystem is well known for the productivity. Fungi play an important role in the nutritive cycle and support the mangrove ecosystem. In the present investigation the authors tries to elucidate marine fungi in selected mangrove ecosystem of North Malabar region of Kerala. 30 marine fungi including 19 Ascomycetes, 1 Basidiomycete and 10 Mitosporic fungi were encountered. Backwater suppo...
in the course of studies about fungi associated with pistachio (pistacia vera l.) die-back disease in the ghaen region of southern khorasan (iran), one species of geosmithia was found. the isolates were identified as geosmithia lavendula (raper & fennell) pitt based on its morphological and molecular properties. the genus geosmithia (ascomycota: hypocreales) is belonging to mitosporic filame...
In the present article, two new mitosporic spccies are introdued, namely: Cercospora fraxinicola Ershad, sp. nov. on Fraxinus rotundifolia and Ramularia rubicola Ershad, sp. nov. on Rubus caesicus.
