Download or read book Mycorrhizal Technology in Agriculture written by S. Gianinazzi and published by Birkhäuser. This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arbuscular Mycorrhiza (AM) is the most common mycorrhizal type involved in agricultural systems, and the most widespread plant root symbiosis. The fungi involved (Glomales) are known to promote plant growth and health by acting as biofertilizers, bioprotectors and bioregulators. The main aim of this book is to provide readers with theoretical and applied knowledge essential for the use of AM fungi in improving plant health and fitness, production of high quality food and in conservation of natural resources. The different chapters target understanding the role of AM fungi in sustainable crop production, discussing ways to improve biological equilibria between microorganisms in the mycorrhizosphere, analysing genetic, physiological, cellular and molecular bases of AM functioning and establishing technologies for inoculum production, according to the regulatory guidelines for application.

Download or read book Characterization and Manipulation of the Willow Microbiome for the Phytoremediation of Petroleum Hydrocarbon Contaminated Soil written by Stacie Tardif and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Phytoremediation, a leading pioneer of green remediation, is an attractive low-cost alternative to conventional soil remediation approaches. However, it is unable to effectively compete in the market due to its lengthy decontamination rates. As such, a detailed understanding of the microbiome dynamics associated with phytoremediation systems is essential in order to optimize degradation processes. The objective of this research was to characterize the influence of compartment, contamination, cultivar type and inoculation on microbiomes associated with willow (Salix spp.) cultivars growing in petroleum hydrocarbon (PHC)-contaminated soil. Next generation sequencing of bacterial 16S rRNA gene and fungal internal transcribed spacer (ITS) region was used in combination with in-depth multivariate statistics to identify the microbial communities in the soil and in the roots and stems of Salix species. In the first phase of this study, the microbiomes of S. purpurea and S. miyabeana growing in soils from a petrochemical site at different contamination concentrations were characterized. The level of PHC-contamination significantly influenced the microbiome with compartment-specific effects, while significant differences were observed between bacterial and fungal community profiles. Root bacterial communities were made up of a subset of rhizosphere bacteria and consequently, largely shaped by the surrounding environment. Increasing contamination resulted in shifts in the microbiome composition, favoring hydrocarbon degraders and microorganisms associated with plant health. These shifts were less drastic in the rhizosphere and in the root and stem tissues as the plant provided a protective buffer zone against increasing contamination. Isolation and characterization of endophytic bacterial strains living in the roots of S. purpurea and S. miyabeana growing in high concentrations of PHCs was then performed in the second phase of this study. Candidate strains showing polycyclic aromatic hydrocarbon (PAH) degradation and plant growth promotion potential were tested in a 4-month long single and mixed strain inoculation study. Plant growth parameters were monitored over time for individual pots, in addition to the microbial community structures and decontamination percentages, which were examined at the beginning and end of the growing season. An average decontamination of 65% of the PHC-contamination was achieved across all treatments. Inoculation treatments significantly modified the rhizosphere microbial communities, an effect that remained visible after 4 months of growth. Although this inoculation did not have the expected effect on plant growth and decontamination, a legacy effect of treatment inoculation was observed on bacterial and fungal soil and root microbial communities, suggesting that the willow microbiome can be modified by inoculation with bacterial endophytes." --
Download or read book Phyto and Rhizo Remediation written by Naveen Kumar Arora and published by Springer Nature. This book was released on 2019-11-15 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing human population and the associated activities have negatively influenced the ecosystems and life on earth. The continuous addition of agrochemicals, heavy metals and industrial wastes/ effluents in the ecosystems have caused great harm, including loss of productivity, biodiversity, climate change and diseases in plants, animals and humans, resulting in increased marginal lands and endangered sustainability of life on earth. Hence, there is an urgent need to reverse the impact of dangerous pollutants through a holistic, sustainable and biotic approach. Bioremediation involves the utilization of biological systems, mainly plants (phytoremediation) or microorganisms or both in combination (rhizoremediation) for the removal or degradation of pollutants and revive the habitats in an eco-friendly manner. Recently, there have been many success stories related to bioremediation involving plants or plant-microbe interactions. These success stories are related to the removal of heavy metals, pesticides, polyaromatic hydrocarbons, explosives, radionuclides or reduction of biological oxygen demand, total dissolved solids, total suspended solids, oil spills in water bodies. Rhizoremediation has also been successfully used for reclamation of saline or marginal soils. With the range of pollutants and the total area (on earth) covered by these toxic chemicals, it is important that these eco-friendly technologies be utilized in a better way. The book throws light on the recent happenings, research and success stories related to bioremediation of polluted habitats through phytoremediation or rhizoremediation. The book also highlights some of the significantly important plant and microbial species involved in remediation, the physiology, biochemistry and the mechanisms of remediation by various plants and microbes, and suggestions for future improvement of bioremediation technology.

Download or read book In Situ Cultivation of Potential PAH Degrading Bacteria from Coastal Sediment written by Kyle Benkel and published by . This book was released on 2020 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil spills can introduce potentially carcinogenic pollutants, such as polycyclic aromatic hydrocarbons (PAHs), into coastal environments. Bioremediation uses the natural microorganisms in the environment to remove these pollutants. Traditional studies of these organisms are limited in the types of bacteria isolated due to the limitations of traditional culturing methods. In this study, diffusion chambers were used to culture and isolate potential PAH degrading bacteria from the coastal sediment obtained from the Chandeleur Islands. The diffusion chambers trapped bacteria in agar that contained 1 ppm benzo[a]pyrene. The bacteria were isolated from the diffusion chambers, and the 16S rRNA gene was sequenced to identify the bacteria. Seven unique bacteria isolates were obtained and were found to be genetically similar to bacteria from the Bacteroidetes and Alphaproteobacteria phyla. It was concluded that the diffusion chamber approach provided an environment that promoted the growth of potential PAH degrading bacteria. Exploration in the use of diffusion chambers should continue in research of PAH biodegradation and the uncultivability of microorganisms.
