Steady-State Growth under Inorganic Carbon Limitation Conditions Increases Energy Consumption for Maintenance and Enhances Nitrous Oxide Production in Nitrosomonas europaea

Creator:: Mellbye, Brett L., Giguere, Andrew, Chaplen, Frank, Bottomley, Peter J., and Sayavedra-Soto, Luis A.
Abstract:: Nitrosomonas europaea is a chemolithoautotrophic bacterium that oxidizes ammonia (NH₃) to obtain energy for growth on carbon dioxide (CO₂) and can also produce nitrous oxide (N₂O), a greenhouse gas. We interrogated the growth, physiological, and transcriptome responses of N. europaea to conditions of replete (>5.2 mM) and limited inorganic carbon...

Thauera butanivorans sp. nov., a C₂–C₉ alkane-oxidizing bacterium previously referred to as ‘Pseudomonas butanovora’

Creator:: Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: The placement of ‘Pseudomonas butanovora’ in the genus Thauera was proposed previously, based on 16S rRNA gene sequence analysis, upon further studies of taxonomical characteristics. In this study, physiological characteristics and DNA–DNA reassociation data are presented and the transfer of ‘P. butanovora’ to the genus Thauera is proposed. The original...

Kinetic characterization of the soluble butane monooxygenase from Thauera butanivorans, formerly ‘Pseudomonas butanovora’

Creator:: Cooley, Richard B., Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: Soluble butane monooxygenase (sBMO), a three-component di-iron monooxygenase complex expressed by the C2–C9 alkane-utilizing bacterium Thauera butanivorans, was kinetically characterized by measuring substrate specificities for C1–C5 alkanes and product inhibition profiles. sBMO has high sequence homology with soluble methane monooxygenase (sMMO) and shares a similar substrate range, including gaseous and...

Identifying Potential Mechanisms Enabling Acidophily in the Ammonia-Oxidizing Archaeon "Candidatus Nitrosotalea devanaterra"

Creator:: Lehtovirta-Morley, Laura E., Sayavedra-Soto, Luis A., Gallois, Nicolas, Schouten, Stefan, Stein, Lisa Y., Prosser, James I., and Nicol, Graeme W.
Abstract:: Ammonia oxidation is the first and rate-limiting step in nitrification and is dominated by two distinct groups of microorganisms in soil: ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB). AOA are often more abundant than AOB and dominate activity in acid soils. The mechanism of ammonia oxidation under acidic conditions has...

Ca. Nitrososphaera and Bradyrhizobium are inversely correlated and related to agricultural practices in long-term field experiments

Creator:: Zhalnina, Kateryna, de Quadros, Patricia D., Gano, Kelsey A., Davis-Richardson, Austin, Fagen, Jennie R., Brown, Christopher T., Giongo, Adriana, Drew, Jennifer C., Sayavedra-Soto, Luis A., Arp, Daniel J., Camargo, Flavio A. O., Daroub, Samira H., Clark, Ian M., McGrath, Steve P., Hirsch, Penny R., and Triplett, Eric W.
Abstract:: Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community. Three different study sites were used to identify microorganisms that correlate with agricultural land use and to determine which factors regulate the relative abundance of the microbial...

Use of aliphatic n-alkynes to discriminate soil nitrification activities of ammonia-oxidizing thaumarchaea and bacteria

Creator:: Taylor, Anne E., Vajrala, Neeraja, Giguere, Andrew T., Gitelman, Alix I., Arp, Daniel J., Myrold, David D., Sayavedra-Soto, Luis, and Bottomley, Peter J.
Abstract:: Ammonia (NH₃)-oxidizing bacteria (AOB) and thaumarchaea (AOA) co-occupy most soils, yet no short-term growth-independent method exists to determine their relative contributions to nitrification in situ. Microbial monooxygenases differ in their vulnerability to inactivation by aliphatic n-alkynes, and we found that NH₃ oxidation by the marine thaumarchaeon Nitrosopumilus maritimus was unaffected...

Complete genome sequence of Nitrosomonas sp. Is79, an ammonia oxidizing bacterium adapted to low ammonium concentrations

Creator:: Bollmann, Annette, Sedlacek, Christopher J., Norton, Jeanette, Laanbroek, Hendrikus J., Suwa, Yuichi, Stein, Lisa Y., Klotz, Martin G., Arp, Daniel J., Sayavedra-Soto, Luis, Lu, Megan, Bruce, David, Detter, Chris, Tapia, Roxanne, Han, James, Woyke, Tanja, Pitluck, Sam, Pennacchio, Len, Nolan, Matt, Land, Miriam L., Huntemann, Marcel, Deshpande, Shweta, Han, Cliff, Chen, Amy, Kyrpides, Nikos, Movromatis, Konstantinos, Markowitz, Victor, Szeto, Ernest, Ivonova, Natalia, Mikhailova, Natalia, Pagani, Ioanna, Pati, Amrita, Peters, Lin, Ovchinnikova, Galina, Goodwin, Lynne A., and Lucas, Susan M.
Abstract:: Nitrosomonas sp. Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family Nitrosomonadaceae within the phylum Proteobacteria. Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Nitrosomonas sp. Is79 is an ammonia oxidizer of high...

Satellite-derived variability in chlorophyll, wind stress, sea surface height, and temperature in the northern California Current System

Creator:: Venegas, Roberto M., Strub, P. Ted, Beier, Emilio, Letelier, Ricardo M., Thomas, Andrew C., Cowles, Timothy J., James, Corinne, Soto-Mardones, Luis, and Cabrera, Carlos
Abstract:: Satellite-derived data provide the temporal means and seasonal and nonseasonal variability of four physical and biological parameters off Oregon and Washington (41°–48.5°N). Eight years of data (1998–2005) are available for surface chlorophyll concentrations, sea surface temperature (SST), and sea surface height, while six years of data (2000–2005) are available for...

Oceanographic and climatic variation drive top-down/bottom-up coupling in the Galápagos intertidal meta-ecosystem

Creator:: Vinueza, Luis R., Menge, Bruce A., Ruiz, Diego, and Palacios, Daniel M.
Abstract:: The impact of herbivores on primary producers in differing oceanographic regimes is a matter of intense ecological interest due to ongoing changes in their abundance, that of their predators, and anthropomorphic alteration of nutrient cycles and climatic patterns. Interactions between productivity and herbivory in marine habitats have been studied on...

Nitric oxide-mediated oxidative damage and the progressive demise of motor neurons in ALS

Creator:: Drechsel, Derek A., Estevez, Alvaro G., Barbeito, Luis, and Beckman, Joseph S.
Abstract:: Oxidative damage is a common and early feature of Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders. Dr. Mark Smith and his colleagues have built the case for oxidative stress being a primary progenitor rather than a secondary end-stage epiphenomenon of neurodegeneration. They proposed that reactive...
