Biochemistry and genetics of autotrophy in Methanococcus [PDF]

open access: yes, 2009
The project investigated fundamental aspects of carbon metabolism and genetics in the methane-producing archaeon Methanococcus maripaludis. The project yielded 23 peer-reviewed publications and five reviews from 1997-2007. PDFs of the peer-reviewed publications are included in the next section. Some papers of special interest are listed below.

Autotrophic vs. heterotrophic microalgae: Juxtaposition of performances in treating organic-rich effluent

open access: yesDesalination and Water Treatment
Microalgae-based wastewater treatment is an alternative to physico-chemical and bacteria-based technologies. Microalgae-based wastewater treatment showed enormous potential, not only exhibiting excellent pollutant removal efficiencies but also unlimited ...

Net community production of oxygen derived from in vitro and in situ 1-D modeling techniques in a cyclonic mesoscale eddy in the Sargasso Sea [PDF]

open access: yesBiogeosciences, 2009
It has been proposed that the disagreement traditionally reported between in vitro incubation and in situ estimates of oxygen net community production (NCP) could be explained, at least partially, by undersampling episodic pulses of net autotrophy ...

Vegetation transitions drive the autotrophy–heterotrophy balance in Arctic lakes

open access: yesLimnology and Oceanography Letters, 2018
“Arctic greening” will alter vegetation quantity and quality in northern watersheds, with possible consequences for lake metabolic balance. We used paleolimnology from six Arctic lakes in Greenland, Norway, and Alaska to develop a conceptual model ...

Analyzing microbial communities and metabolic functions in estuaries affected by human activity to uncover bioelectrochemical system potential

open access: yesEnvironmental Advances
In the context of bioelectrochemical systems (BES), a profound understanding of the taxonomic composition within indigenous microbial communities is crucial.

Carbon fixation by basalt-hosted microbial communities

open access: yesFrontiers in Microbiology, 2015
Oceanic crust is a massive potential habitat for microbial life on Earth, yet our understanding of this ecosystem is limited due to difficulty in access. In particular, measurements of rates of microbial activity are sparse. We used stable carbon isotope

Toxicology and efficacy of tumor-targeting Salmonella typhimurium A1-R compared to VNP 20009 in a syngeneic mouse tumor model in immunocompetent mice. [PDF]

open access: yes, 2017
Salmonella typhimurium A1-R (S. typhimurium A1-R) attenuated by leu and arg auxotrophy has been shown to target multiple types of cancer in mouse models.

Net autotrophy and heterotrophy in the Pontevedra Ria upwelling system (NW Iberian margin)

open access: yesCiencias Marinas, 2005
A non-stationary state mass balance of the type advocated by the International Geosphere-Biosphere Programme/Land-Ocean Interactions in the Coastal Zone (IGBP/LOICZ) has been used to assess net ecosystem metabolism in the Pontevedra Ria (NW Spain), a ...

Effects of mutation and some environmental factors on the physiology and pathogenicity of selected bacteria [PDF]

open access: yes
Studies with mutants of Staphylococcus aureus lacking some virulence factors suggest that the presence of deoxyribonuclease correlates with mouse pathogenicity of S.
