Potassium fixation and release by phillosilicate clay minerals in soils are very important processes influencing the availability of K to plants. This investigation was conducted to determine the potassium fixation capacity and charge characteristics of soil clays of 15 surface soils (0-30 cm) from central and northern Iran. After clay particle separation, both total and tetrahedral cation ex...
Currently, there is a worldwide growing interest in the occurrence and diversity of fungi and their secondary metabolites in aquatic systems, especially concerning their role in water quality and human health. However, this concern is hampered by the scant information that is available in the literature about aquatic fungi and how they affect water quality. There are only few published reports ...
geographical situation of gilan province, its weather and suitable conditions for agriculture, plus its neighboring with russia, have prepared the way for cultural, political and economical relations and interchanges between iran and russia. being called “the gate of europe”, the province also receives many tourists from many countries, especially russia. many of these tourists have recorded de...
Melanized fungi are frequently considered as ubiquitous saprobes commonly found on decomposing plant debris, dead plant material, rotten wood, or soil. Over 70 genera and 150 species of dematiaceous fungi have been implicated in human and animal diseases. The clinical syndromes caused by latter fungi are differentiated based on histologic criteria into phaeohyphomycetoma, chromoblastomycosis,...
Arbuscular mycorrhizal fungi (AMF) are a group of obligate plant symbionts which can promote plant nutrition. AMF communities are diverse, but the factors which control their assembly in space and time remain unclear. In this study, the contributions of geographical distance, environmental heterogeneity and time in shaping AMF communities associated with Miscanthus giganteus (a perennial grass ...
Negative population feedbacks mediated by natural enemies can promote species coexistence at the community scale through disproportionate mortality of numerically dominant (common) tree species. Simultaneously, associations with arbuscular mycorrhizal fungi (AMF) can result in positive effects on tree populations. Coupling data on seedling foliar damage from herbivores and pathogens and DNA seq...
Asthma is a complicated disorder, whose prevalence has increased over the past few decades.Asthma is characterized by infiltration of inflammatory leukocytes along with enhancedproinflammatory cytokines and chemokines. Fungi are now far more widely being considered as thedominant extrinsic trigger for asthma. Fungi are linked to the severity of asthma in many ways. Somedifferences between studi...
Background and Objective: Lead is one of the heavy metals which releases into water and soil resources through industrial wastes and poses serious harmful effects on human health. This study was conducted to determine the biosorption capacity of lead by active biomass of lead resistant fungi. Materials and methods: In this study the lead –resistant fungi were isolated from effluent of Zanjan Le...
the aim of this study was identification of fungi in indoor and outdoor of asthmatic patients´ home environment. opened plates (containing of malt extract agar media) were used for isolation of fungi in the air of indoor (n=360) and outdoor (n=180) of 90 asthmatic patients̉ home living in the city of sari at the level of breathing height. plates were incubated in room temperature for 7-14 days. ...
