Ice nucleation activity in the widespread soil fungus Mortierella alpina
Biological residues in soil dust are a potentially strong source of atmospheric ice nuclei (IN). So far, however, the abundance, diversity, sources, seasonality, and role of biological – in particular, fungal – IN in soil dust have not been characterized. By analysis of the culturable fungi in topsoils, from a range of different land use and ecosystem types in southeast Wyoming, we found ice-nu...
متن کاملSesamin inhibits lysophosphatidylcholine acyltransferase in Mortierella alpina.
The filamentous fungus, Mortierella alpina, accumulates complex lipids relatively rich in arachidonic acid (C(20:4) Delta(5,8,11,14)). The lignan, sesamin, has been used to reduce arachidonic acid production by specifically inhibiting Delta(5)-desaturation [Shimizu, Akimoto, Shinmen, Kawashima, Sugano and Yamada (1991) Lipids 26, 512-516]. Microsomal membrane preparations from M. alpina exhibit...
متن کاملFirst Report of Mortierella alpina (Mortierellaceae, Zygomycota) Isolated from Crop Field Soil in Korea
A new recorded species of Mortierella was recovered during the investigation of fungal communities in soil samples collected from different locations of Gangwon-do, Korea. The species was identified and described as Mortierella alpina on the basis of phylogenetic analysis of internal transcribed spacer sequences and morphological characteristics. This species has not been officially reported fr...
متن کاملEcotoxicity of a polycyclic aromatic hydrocarbon (PAH)-contaminated soil.
Soil samples from a former cokery site polluted with polycyclic aromatic hydrocarbons (PAHs) were assessed for their toxicity to terrestrial and aquatic organisms and for their mutagenicity. The total concentration of the 16 PAHs listed as priority pollutants by the US Environmental Protection Agency (US-EPA) was 2634+/-241 mg/kgdw in soil samples. The toxicity of water-extractable pollutants f...
متن کامل2,4-Dichlorophenol degradation by the soil fungus Mortierella sp.
We investigated the degradation pathways and kinetics of 2,4-dichlorophenol (DCP) by an endemic soil fungus, Mortierella sp. (Zygomycetes). Mortierella sp. degraded 32% of added DCP (final concentration, 250 microM) within 1 h. We identified four aromatic metabolites and found two DCP degradation pathways (a hydroxylation pathway and a dechlorination pathway). This is the first report of a dech...
