Download or read book Microbial Metal Respiration written by Johannes Gescher and published by Springer Science & Business Media. This book was released on 2014-02-21 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbes can respire on metals. This seemingly simple finding is one of the major discoveries that were made in the field of microbiology in the last few decades. The importance of this observation is evident. Metals are highly abundant on our planet. Iron is even the most abundant element on Earth and the forth most abundant element in the Earth’s crust. Hence, in some environments iron, but also other metals or metalloids, are the dominant respiratory electron acceptors. Their reduction massively drives the carbon cycle in these environments and establishes redox cycles of the metallic electron acceptors themselves. These redox cycles are not only a driving force for other biotic reactions but are furthermore necessary for initiating a number of geochemically relevant abiotic redox conversions. Although widespread and ecologically influential, electron transfer onto metals like ferric iron or manganese is biochemically challenging. The challenge is to transfer respiratory electrons onto metals that occur in nature at neutral pH in the form of metal oxides or oxihydroxides that are effectively insoluble. Obviously, it is necessary that the microbes specially adapt in order to catalyze the electron transfer onto insoluble electron acceptors. The elucidation of these adaptations is an exciting ongoing process. To sum it up, dissimilatory metal reduction has wide-spread implications in the field of microbiology, biochemistry and geochemistry and its discovery was one of the major reasons to establish a novel scientific field called geomicrobiology. Recently, the discovery of potential applications of dissimilatory metal reducers in bioremediation or current production in a microbial fuel cell further increased the interest in studying microbial metal reduction.
Download or read book Microbial Biocontrol Sustainable Agriculture and Phytopathogen Management written by Ajay Kumar and published by Springer Nature. This book was released on 2022-05-04 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This first volume of a two-volume work presents the manifold applications of beneficial microbes and microbiomes in plant growth promotion, in enhancing crop resilience and in control of phytopathogens through microbial antagonists. In-depth insights into latest technologies such as biopriming of seeds and soil inoculation of rhizosphere microorganisms are provided. The two-volume work “Microbial Biocontrol” introduces mechanisms of plant-microbe interactions and explores latest strategies of how microbes can be applied in biocontrol and management of plant pathogens, replacing chemical fertilizers and pesticides. The book covers different groups of microorganisms such as bacteria, fungi, but also the interplay of entire microbiomes, and reviews their specific benefits in crop growth promotion, in enhancing the plants’ tolerance against biotic and abiotic stress as well as in post-harvest management of various plant diseases. Novel tools such as CRISPR/Cas9 and microbe derived nanoparticles are also addressed besides the legal aspects of biocontrol applications. Today, rising global population and changing climatic conditions emerge as a major challenge for agronomist farmers and researchers in fulfilling the requirements of global food production. The conventional agricultural practices utilize undistributed use of chemical fertilizers and pesticides to enhance growth and yield of agricultural products and fresh foods, but their extensive and continuous use have led to a range of negative consequences on the food quality and safety, to environment as well as to human and animal health. Microbial biocontrol applications are presented as a solution, paving the way to a sustainable agriculture in compliance with the UN Sustainable Development Goals (SDG). The book addresses researchers in academia and agriculture.

This book was released on 2021-01-22 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the success of this Research Topic http://journal.frontiersin.org/ researchtopic/3298/regulation-of-gene-expression-in-enteropathogenic-bacteria, we are happy to launch a second edition of the project. Pathogenic bacteria have evolved numerous strategies to survive in and to attack hosts, which can be reflected by transcriptional and posttranscriptional changes in specific genes especially including those encoding virulence determinants. Regulation of gene expression by regulatory proteins and non-coding RNAs enables the pathogens to adapt their metabolic needs and to coordinately express virulence determinants during different stages of infection.
Download or read book Investigations of the Periplasmic Physiology of Phenazines in Pseudomonas for Improved Mediated Electron Transfer in Bioelectrochemical Systems written by Anthony Chukwubuikem and published by . This book was released on 2022* with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenazines are natural products of some microorganisms, especially bacteria. They are very peculiar to Pseudomonas aeruginosa where they are a pathogenic factor performing several roles. These include acting as an antibiotic against non-producing bacteria, facilitating iron acquisition, and enhancing the survival of P. aeruginosa in oxygen-limited environment by shuttling electrons to distant oxygen or other extracellular electron acceptors- a process known as extracellular electron transfer (EET). The latter function is employed in a bioelectrochemical system (BES) using phenazines redox mediators to shuttle electrons from microorganisms to the anode (electrode) thereby generating electricity. This phenazine EET in the BES is being explored to develop bioprocesses, which can function even under limited oxygen conditions. Hence, biotechnologically important strains such as P. putida KT2440 and E. coli have been engineered to produce phenazines. A challenge, however, in using phenazines as electron mediators in a BES is that only a small proportion or percentage of electrons generated from the metabolism of a given substrate can be delivered to the anode, i.e., the coulombic efficiency of phenazine EET is low. We wanted to unravel the reasons behind the low coulombic efficiency, and we hypothesized that most of the electrons that are available for phenazine reduction are obtained in the periplasm of the cell. This is because no putative re-entry path into the cytoplasm has so far been described for the phenazines. Thus, it was not certain if the phenazines, once released from the cytoplasm where they are produced, can re-access this part of the cell. Consequently, only electrons emanating from the various metabolic processes in the periplasm would be available for phenazine reduction, possibly excluding electrons from the cytoplasm where the bulk of the metabolic activities occur. ...

Available in PDF, EPUB and Kindle. Book excerpt: The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.
