Potential importance of bacteria and fungi in nitrate assimilation in soil
Soil microorganisms can use a wide range of N compounds but are thought to prefer NH4 . Nevertheless, N isotope dilution studies have shown that microbial immobilization of NO3 can be an important process in many soils, particularly relatively undisturbed soils. Our objective was to develop a method for measuring NO3 immobilization potential so that the relative contributions of bacteria and fu...
متن کاملCultivation Effect of Chitinase-Transgenic Cotton on Functional Bacteria and Fungi in Rhizosphere and Bulk Soil
Background: In consideration for the increasing widespread use of genetically modified (GM) crops, one of the important issues for assessment is the effect of GM crops on soil microbial communities Objectives: In this study, T2 chitinase-transgenic cotton (line #57) and its non-transgenic line were investigated for bacterial and fungal dynamics...
متن کاملFungi and bacteria as helping agents for remediation of a Pb - contaminated soil by Onopordum acanthium
Phytoremediation is a promising method for remediation of heavy metals (HMs) contaminated environments. However, the main failures are the limited bioavailabilty of HMs such as lead (Pb) in the soil and/or suppressed plant growth in contaminated sites. These limitations specifically occur in semi-arid zone environments such as calcareous soils. Arbuscular mycorrhizal fungi (AMF) and plant growt...
متن کاملDetermination of the relative abundance and distribution of bacteria and fungi in Bonny light crude oil-contaminated sandy loam soil
This study was undertaken to investigate the effects of Bonny light crude oil (specific gravity = 0.81; API gravity 43.2 0 ) on the numerical composition of soil bacteria and fungi and relative distribution of Gram positive and Gram negative soil bacteria. Eight different levels of the crude oil (0.5, 1.0, 2.0, 2.5, 5.0, 10.0, 15.0 or 20.0% v/w of soil) were used for the controlled pollution of...
متن کاملInteractions between Soil Bacteria and Arbuscular Mycorrhizal Fungi
Toljander, J.F. 2006. Interactions between Soil Bacteria and Arbuscular Mycorrhizal Fungi. Doctoral dissertation. ISSN 1652-6880, ISBN 91-576-7088-9 The extraradical mycelium (ERM) of mycorrhizal fungi constitutes an important pathway for the translocation of energy-rich photoassimilates from plant to soil. Because of the large surface of the mycelium, and its provision of carbon, the ERM poten...
