mSphere, 2020 The ability to form biofilms is shared by many microorganisms, including archaea. Cells in a biofilm are encased in extracellular polymeric substances that typically include polysaccharides, proteins, and extracellular DNA, conferring protection while ...

Revista Brasileira de Ciência do Solo, 2010 A alta difusividade do oxigênio em diversos materiais dificulta a criação e, ou, manutenção de um ambiente livre de O2. As técnicas utilizadas são pouco eficientes na exclusão do O2 e, portanto, não expressam a condição do solo alagado.

Involvement of ethylene signalling in a non-climacteric fruit: new elements regarding the regulation of ADH expression in grapevine [PDF]
, 2004 Although grape berries have been classified as non climacteric fruits, ongoing studies on grape ethylene signalling lead to challenge the role of ethylene in their ripening. One of the significant molecular changes in berries is the up regulation of ADH

Frontiers in Physiology, 2018 Hypoxia in freshwater ecosystems is spreading as a consequence of global change, including pollution and eutrophication. In the Patagonian Andes, a decline in precipitation causes reduced lake water volumes and stagnant conditions that limit oxygen ...

The pneumococcal response to oxidative stress includes a role for Rgg [PDF]
, 2009 Streptococcus pneumoniae resides in the oxygen-rich environment of the upper respiratory tract, and therefore the ability to survive in the presence of oxygen is an important aspect of its in vivo survival. To investigate how S.

Exploring the Molecular Machinery of Denitrification in Haloferax mediterranei Through Proteomics
Frontiers in Microbiology, 2020 Many proteins and enzymes involved in denitrification in haloarchaea can be inferred to be located between the cytoplasmic membrane and the S-layer, based on the presence of a Tat signal sequence and the orientation of the active site that some of these ...

How obligatory is anaerobiosis? [PDF]
Molecular Microbiology, 2008 SummaryHistorically many bacteria have been classified as obligate anaerobes. They have been construed as wholly intolerant of oxygen, a feature that was originally ascribed to their lack of superoxide dismutases and catalases. Clostridial species were regarded as classic examples.

Continuous Anaerobiosis for Cultivation of Spirochetes.
Experimental Biology and Medicine, 1964 SummaryApparatus and procedures have been developed for bacteriological work based on a vacuum-tight glove box with lock, in which an anaerobic working atmosphere has been maintained by evacuation, followed by removal of residual and diffusing oxygen with hydrogen and a catalyst that does not require pre-heating.

Plant mitochondrial function during anaerobiosis [PDF]
Annals of Botany, 2008 Under hypoxic conditions, plant mitochondria preserve the capacity to oxidize external NADH, NADPH and tricarboxylic acid cycle substrates. Nitrite serves as an alternative electron acceptor at the level of cytochrome oxidase, with possibly complex III and the alternative oxidase also being involved.

Temperature affects the use of storage fatty acids as energy source in a benthic copepod (Platychelipus littoralis, Harpacticoida) [PDF]
, 2016 The utilization of storage lipids and their associated fatty acids (FA) is an important means for organisms to cope with periods of food shortage, however, little is known about the dynamics and FA mobilization in benthic copepods (order Harpacticoida ...
