Evolution, metabolism and molecular mechanisms underlying extreme adaptation of euryarchaeota and its biotechnological potential
Archaeal organisms harbor many unique genotypic and phenotypic properties, testifying their peculiar evolutionary status. Thus, the so‐called extremophiles must be adequately adapted to cope with many extreme environments ...
Revealing archaeal diversity patterns and methane fluxes in Admiralty Bay, King George Island, and their association to Brazilian Antarctic Station activities
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The study of Antarctic archaeal communities adds information on the biogeography of this group and helps understanding the dynamics of biogenic methane production in such extreme habitats. Molecular methods were combined ...
Comparative in vitro evaluation of forage legumes (prosopis, acacia, atriplex, and leucaena) on ruminal fermentation and methanogenesis
(KIELANOWSKI INST ANIMAL PHYSIOLOGY NUTRITIONJABLONNA, 2012)
Two experiments in vitro were conducted to evaluate four Egyptian forage legume browses, i.e., leaves of prosopis (Prosopis juliflora), acacia (Acacia saligna), atriplex (A triplex halimus), and leucaena (Leucaena ...
Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ...
The geomicrobiology of iron, cobalt, nickel and manganese in lateritic tropical soils from the Santa Elena Peninsula, Costa Rica
There is an increasing interest in the biogeochemistry of metals, like cobalt, fuelled by the growing need for batteries and other high technology products. Bioprocessing of Co has been proposed to improve its recovery ...

Efluxo de metano relacionado com ácidos orgânicos no solo e carbono de exsudados radiculares no cultivo do arroz irrigado
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2018-07-20)
In worldwide greenhouse gases generation (GHGs) agriculture is one of the principal activities. In Brazil, as a reflection of the importance agriculture in economy, it is estimated that 75% of emissions of carbon dioxide ...
