This book was released on 2022-06-14 with total page 922 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbes and Microbial Biotechnology for Green Remediation provides a comprehensive account of sustainable microbial treatment technologies. The research presented highlights the significantly important microbial species involved in remediation, the mechanisms of remediation by various microbes, and suggestions for future improvement of bioremediation technology. The introduction of contaminants, due to rapid urbanization and anthropogenic activities, into the environment causes unsteadiness and distress to the physicochemical systems, including living organisms. Hence, there is an immediate global demand for the diminution of such contaminants and xenobiotics which can otherwise adversely affect the living organisms. Over time, microbial remediation processes have been accelerated to produce better, eco-friendlier, and more biodegradable products for complete dissemination of these xenobiotic compounds. The advancements in microbiology and biotechnology lead to the launch of microbial biotechnology as a separate area of research and contributed dramatically to the development of the areas such as agriculture, environment, biopharmaceutics, and fermented foods. Microbes stand as an imperative, efficient, green, and economical alternative to conventional treatment technologies. The proposed book provides cost-effective and sustainable alternatives. This book serves as a reference for graduate and postgraduate students in environmental biotechnology and microbiology as well as researchers and scientists working in the laboratories and industries involved in research related to microbiology, environmental biotechnology, and allied research. - Discusses important microbial activities, such as biofertilizer, biocontrol, biosorption, biochar, biofilm, biodegradation, bioremediation, bioclogging, and quorum sensing - Covers all the advanced microbial bioremediation techniques which are finding their way from the laboratory to the field for revival of the degraded agro-ecosystems - Examines the role of bacteria, fungi, microalgae, Bacillus sp., Prosopis juliflora, Deinococcus radiodurans, Pseudomonas, methanotrophs, siderophores, and PGPRs as the biocontrol and green remediator agents for soil sustainability

Available in PDF, EPUB and Kindle. Book excerpt: Technology has always played a major role in oceanography; new advances have changed how we observe the ocean. Among the many interests driving marine carbon observations, ocean acidification and marine carbon dioxide removal are at the forefront of research requiring better sensing options. There has been a recent explosion of interest in adapting existing technologies and developing new methods to provide much greater coverage of monitoring and better constraining the marine carbon cycle. As new players come to the field from various industries and backgrounds, we often field questions about why we don’t yet have commercially available in situ sensors for more biogeochemical parameters. There are many challenges to working in marine environments regardless of what we are trying to measure, and producing quality data on the time and space scales required for carbon cycle work is a huge task. Many clever people have faced these challenges with fervor and creativity, and we look forward to exciting new developments in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Existing techniques in use at the Ocean Chemistry Laboratory for measureable parameters of inorganic carbon in seawater are discussed. These parameters are dissolved inorganic carbon (?CO2), carbonate alkalinity, partial pressure of CO2 in air and seawater (pCO2), and C13/C12 ratio and C14/C12 ratio, measured by infrared analysis, potentiometric titration, mass spectrometry, and low level radioactive gas counting, respectively. The significance of the measured variability in atmospheric CO2 and exchange with oceanic CO2 is outlined.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, I present several tools to assist the community in making accurate and precise manipulations and measurements of carbonate chemistry parameters, which are essential for understanding, interpreting, and predicting the anthropogenic impact on the chemistry of our oceans. As the frequency of carbonate chemistry measurements increases with interest in the ocean's response to climate change, there is a continued need for confidence in the measurements to ensure data quality and consequent data usefulness. First, I explain the results of an international inter-laboratory comparison of various carbonate chemistry measurements. The majority of the results exhibit agreement within 0.5% of the assigned value for total alkalinity and total dissolved inorganic carbon, with significantly more variability in pH measurements. In many cases there is evidence of significant loss of CO2 from the seawater samples, a particularly alarming bias given how critical these measurements are to the understanding of increasing anthropogenic carbon in our oceans. Carbonate chemistry measurements can also be compromised when taken from environments such as coastal and estuarine seawater, as well as laboratory cultures and aquaria, containing large numbers of suspended biogenic particles. The presence of these particles in a seawater sample may alter the results of the analysis for carbonate chemistry parameters including total alkalinity, total dissolved inorganic carbon, and pH. In this dissertation, I present the verification of a filtration method using a peristaltic pump and enclosed filter housing, which does not alter the dissolved CO2 content of the seawater sample, and thus is suitable for filtration of samples before analysis. Finally, manipulation of carbonate chemistry in the laboratory is a crucial tool for studying the impacts of increasing CO2 on organisms and communities, however is not always straightforward. I developed a carefully controlled aquarium system capable of manipulating the carbonate chemistry, oxygen levels, and temperature of seawater. The multi-stressor nature of the control is critical, particularly regarding the investigation of coastal ocean conditions, which are unique in the magnitude of range and temporal variability possible in these parameters. The aquarium system is dynamically controlled such that variability in pH may be introduced across many time scales. The novel tools presented in this dissertation for the manipulation and measurements of carbonate chemistry will assist in ensuring greater accuracy and understanding of the impacts of changes in carbon dioxide on our oceans.

This book was released on 2015 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean's sequestration of anthropogenic carbon dioxide has major consequences for global change. Not only does it temper global warming by removing some of the greenhouse gas from the atmosphere, it also results in ocean acidification through the reaction of CO2 and H2O. While the environmental science community is well aware of these issues at a broad, global level, there are notable gaps in our understanding of changes occurring over smaller spaces and shorter times. This dissertation describes novel tools that are being developed and implemented in order to fill those gaps. Specifically, it focuses on autonomous, in situ systems designed to quantify total dissolved inorganic carbon (the sum of all chemical species formed in seawater directly through the addition of CO2 to H2O) and pH (a measure of the proton concentration in seawater. The first two chapters describe a "Micro-Rosette" for microfluidic quantification of total dissolved inorganic carbon (DIC) from profiling floats. Chapter 1 deals specifically with optimization of a gas diffusion cell, an integral component of any liquid-to-liquid (i.e., seawater to receiving solution) DIC extraction technique. 109 unique combinations of gas diffusion cell geometry, seawater volume, and diffusion time were tested to rigorously determine the optimal conditions needed in order to quantify DIC repeatably. Chapter 2 incorporates these findings and implements a sixteen-sample microfluidic collection manifold such that seawater can be captured and stored as a profiling float ascends from 2000 m to the surface and subsequently analyzed once the float returns to its "park depth" (~1000 m), where it remains for over a week. Chapter 1 achieves better than 0.2% repeatability in DIC measurements; the multiplexed collection and analysis in Chapter 2 attains 1%. Chapters 3 and 4 pertain to in situ measurement of seawater pH with the Honeywell Durafet. Well over 100 packages implementing the Durafet have been deployed globally; Chapter 3 lays out best practices for utilizing those packages and validating the resulting data by comparing sensor results to discrete samples and thermodynamically and empirically-derived pH values. Chapter 4 illustrates the use of a Durafet packaged specifically for mobile platforms and surface pH mapping applications.
