Ammonia oxidizing bacteria (AOB) play a central role in the nitrogen cycle by oxidizing ammonia to nitrite. Nitrosomonas europaea ATCC 19718 has been the single most studied AOB that has contributed to our understanding of chemolithotrophic ammonia oxidation. As a closely related species,...

Aerobic methanotrophic bacteria lessen the impact of the greenhouse gas methane (CH4) not only because they are a sink for atmospheric methane but also because they oxidize it before it is emitted to the atmospheric reservoir. Aerobic methanotrophs, unlike anaerobic methane oxidizing archaea,...

Gomes-Yakiwchuk, Sujani

The current understanding of how ammonia oxidizing bacteria (AOB) produce the potent greenhouse gas nitrous oxide is incomplete and inaccurate since most studies are focused on the model organism for the group, Nitrosomonas europaea, which does not represent the physiological diversity of AOB....

Ammonia oxidizers come from two different domains of life, the Archaea and Bacteria, and control a vital step in the global biogeochemical Nitrogen cycle; the conversion of ammonia to nitrite. They are abundant in a wide range of environments including marine and freshwaters, terrestrial soils,...

Methanotrophic bacteria are capable of converting single carbon sources such as methane or methanol, two common industrial waste products, into value-added compounds like bioplastics or biofuels. These microorganisms have significant potential for the mitigation of these low-value industrial...

Methanotrophic bacteria have the potential to act as a platform for several novel bio industrial processes, due to their capacity to convert methane, often from impure sources, into valuable products. These products can include, but are not limited to, isoprenoids for the development of bio-jet...

Animals live in close association with communities of microbes that play important roles modulating host nutrition, immunity, health, and behavior. Many of these microbes live on or in their animal host, most notably in the vertebrate gut, but microbiome studies now encompass disparate taxa from...

Studies on copper as a critical nutrient in methane-oxidizing bacteria (MOB) have mostly focused on the well-characterized “copper switch” in species with dual methane monooxygenase (MMO) variants (Takeguchi & Okura, 2000, Knapp et al., 2007, Kenney et al., 2016). Copper availability dictates...

Methane and methanol are inexpensive and sustainable carbon feedstocks for bioconversion to value-added products. Methane being a greenhouse gas, its conversion has the added benefit of mitigating emissions that affect climate change. Methanotrophic bacteria consume methane and methanol as sole...

Outer membrane vesicles (OMVs) are extracellular vesicles released from the outer leaflet of the membrane of Gram-negative bacteria. These membrane-derived vesicles are found in numerous different phyla of Gram-negative bacteria. OMV functions are as diverse as the bacteria that produce them,...
