This book offers a comprehensive overview of the microbiological fundamentals and biotechnological applications of methanotrophs: aerobic proteobacteria that can utilize methane as their sole carbon and energy source. It highlights methanotrophs’ pivotal role in the global carbon cycle, in which they remove methane generated geothermally and by methanogens. Readers will learn how methanotrophs have been employed as biocatalysts for mitigating methane gas and remediating halogenated hydrocarbons in soil and underground water. Recently, methane has also attracted considerable attention as a potential next-generation carbon feedstock for industrial biotechnology, because of its abundance and low price. Methanotrophs can be used as biocatalysts for the production of fuels, chemicals and biomaterials including methanobactin from methane under environmentally benign production conditions. Sharing these and other cutting-edge insights, the book offers a fascinating read for all scientists and students of microbiology and biotechnology.

This book provides in-depth insights into the most recent developments in different areas of microbial methane and methanol utilization, including novel fundamental discoveries in genomics and physiology, innovative strategies for metabolic engineering and new synthetic approaches for generation of feedstocks, chemicals and fuels from methane, and finally economics and the implementation of industrial biocatalysis using methane consuming bacteria. Methane, as natural gas or biogas, penetrates every area of human activity, from households to large industries and is often promoted as the cleanest fuel. However, one should not forget that this bundle of energy, carbon, and hydrogen comes with an exceptionally large environmental footprint. To meet goals of long-term sustainability and human well-being, all areas of energy, chemicals, agriculture, waste-management industries must go beyond short-term economic considerations and target both large and small methane emissions. The search for new environment-friendly approaches for methane capture and valorization is an ongoing journey. While it is not yet apparent which innovation might represent the best solution, it is evident that methane biocatalysis is one of the most promising paths. Microbes are gatekeepers of fugitive methane in Nature. Methane-consuming microbes are typically small in number but exceptionally big in their impact on the natural carbon cycle. They control and often completely eliminate methane emission from a variety of biological and geothermal sources. The tremendous potential of these microbial systems, is only now being implemented in human-made systems. The book addresses professors, researchers and graduate students from both academia and industry working in microbial biotechnology, molecular biology and chemical engineering.

Methane (CH4) is a greenhouse gas with implications in global climate change. Methanotrophs, organisms capable of consuming CH4, play a key role in regulating atmospheric CH4 emissions. Current estimates and understanding of factors regulating microbial CH4 fluxes are limited. This work contributes to current understanding of methanotroph impacts on CH4 fluxes and biotechnological applications to mitigate CH4 emissions from wastewater.First, empirical relationships between biomarker gene and transcript amounts and activity in model methanotroph M. trichosporium OB3b grown in membrane bioreactors (MBRs) were explored. A strong correlation between per cell CH4 oxidation biomarker pmoA transcript and per cell CH4 oxidation rate was observed across three orders of magnitude. These correlations and effects of short-term substrate (CH4 and O2) limitation on gene expression were further explored in methanotrophs, Methylocystis parvus OBBP and Methylomicrobium album BG8. Results showed correlations between per cell pmoA transcript and per cell activity were maintained across the three methanotroph species studied. A potential, universal trend between cell activity and biomarker levels could allow for better estimates of in situ methanotrophic activity. Substrate limitation induced changes in central carbon metabolism gene expression and elicited a strong stress response in M. album BG8.Lastly, the feasibility of aerobic, single-stage MBRs for treatment of CH4- and NH4+-rich anaerobic wastewaters was investigated. Substrates (CH4 and O2) were delivered via membrane permeation. Effects of O2 membrane pressure, inoculation, retention time, and NO2- additions were explored. Simultaneous nitrification and denitrification occurred in single-stage reactors and removal rates were comparable to those available in the literature. O2 membrane pressure was the main driver for reactor performance and reactor microbial community composition.This work relied on MBRs in the context of microbial CH4 cycling, to explore fundamental relationships between gene expression and microbial activity, and to harness ability of extant microbes in wastewater treatment. These results serve as a foundation for CH4 oxidation biomarkers as predictors of CH4 oxidation rates. The MBR treatment method performance was comparable to available alternative technologies. The results found herein further our knowledge of CH4 cycling organisms and wastewater treatment options, with implications on the global CH4 cycle.

Type II methanotrophic bacteria are superior to Type I methanotrophs in accumulating polyhydroxybutyrate (PHB), a biodegradable alternative to polypropylene and other petro-chemical plastics, under nutrient limiting conditions. We evaluated the growth of Type I and Type II methanotrophs in a 15.2-liter bench-scale fluidized bed reactor (FBR) over a 270-day period. The aim was to identify operational characteristics and selection pressures that would favor Type II over Type I methanotrophs. The results indicate that Type II methanotrophs can be grown in an FBR under the appropriate conditions and that such a method may be a viable means of producing large quantities of biomass for PHB production.
