Major differences in dissolved organic matter characteristics and bacterial processing over an extensive brackish water gradient, the Baltic Sea
(Elsevier Science, 2018-05)
Dissolved organic matter (DOM) in marine waters is a complex mixture of compounds and elements that contribute substantially to the global carbon cycle. The large reservoir of dissolved organic carbon (DOC) represents a ...
The disruptive effect of lysozyme on the bacterial cell wall explored by an in-silico structural outlook
(John Wiley & Sons Inc, 2018-01)
The bacterial cell wall, a structural unit of peptidoglycan polymer comprised of glycan strands consisting of a repeating disaccharide motif [N-acetylglucosamine (NAG) and N-acetylmuramylpentapeptide (NAM pentapeptide)], ...
Environmental heterogeneity determines the ecological processes that govern bacterial metacommunity assembly in a floodplain river system
(Nature Publishing Group, 2020-12-27)
How diversity is structured has been a central goal of microbial ecology. In freshwater ecosystems, selection has been found to be the main driver shaping bacterial communities. However, its relative importance compared ...
How functionalized surfaces can inhibit bacterial adhesion and viability
(American Chemical Society, 2019-09)
Device-associated infections (DAI) remain a serious concern in modern healthcare. Bacterial attachment to a surface is the first step in biofilm formation, which is one of the main causes of DAIs. The development of materials ...
Soil bacterial communities remain altered after 30 years of agriculture abandonment in Pampa grasslands
(Springer, 2020-08)
Old fields are spreading in the world because of agriculture abandonment, and they show a persistence of exotic plant species with little recovery towards the original vegetation composition. Soil biota may also differ ...
Grass dominance drives rhizospheric bacterial communities in a desertic shrub and grassy steppe highland
(Elsevier Gmbh, 2017-05)
The rhizosphere is a dynamic root-soil interface characterized by interactions between soil microorganisms and roots. These interactions can be potential drivers of the structure of the plant and bacterial communities in ...
Spectroelectrochemical examination of the interaction between bacterial cells and gold electrodes
(American Chemical Society, 2007-05)
The interaction between bacterial cells of Pseudomonas fluorescens (ATCC 17552) and gold electrodes was analyzed by cyclic voltammetry (CV) and attenuated total reflection-surface-enhanced infrared absorption spectroscopy ...
KatE from the bacterial plant pathogen Ralstonia solanacearum is a monofunctional catalase controlled by HrpG that plays a major role in bacterial survival to hydrogen peroxide
(Frontiers Media, 2020-07)
Ralstonia solanacearum is the causative agent of bacterial wilt disease on a wide range of plant species. Besides the numerous bacterial activities required for host invasion, those involved in the adaptation to the plant ...
Nanocomposites based on poly(lactic acid) and bacterial cellulose acetylated by an α-hydroxyacid catalyzed route
(Springer/Plenum Publishers, 2019-03)
Poly(lactic acid) (PLA) nanocomposite films reinforced with acetylated bacterial cellulose nanoribbons were prepared by solvent casting. Acetylation of bacterial cellulose (BC) was performed by an innovative and sustainable ...
New insights into bacterial cellulose materials: production and modification strategies
(Universidade de Araraquara, 2018-10)
Komagataeibacter xylinus cultures produced a high amount of bacterial cellulose (BC), which structure consists in a nanoporous network of interlaced fibers. When the culture is performed under static experimental conditions, ...
