Common architectures in cyanobacteria Prochlorococcus cells visualized ...
2021年2月16日 · Transmission electron microscopy (TEM) applied to sliced sections of stained 10, 11, 12, 13 or frozen-hydrated cells 14, 15 has made significant contributions in this area to reveal the...
Direct interaction between marine cyanobacteria mediated by
2024年5月23日 · A combination of TEM, scanning electron microscopy (SEM), fluorescence microscopy, and imaging flow cytometry (IFC; using the Amnis ImageStream MKII system, Luminex) was used to observe and characterize nanotubes in several xenic and axenic cultures of Prochlorococcus and Synechococcus (Fig. 1 and fig. S1).
Cyanobacteria: Model Microorganisms and Beyond - PMC
In this review, the general background is provided on cyanobacteria, including morphology, cell membrane structure, and their photosynthesis pathway. The presence of cyanobacteria in nature, and their industrial applications are discussed, and …
Biogenic regions of cyanobacterial thylakoids form contact sites …
2019年4月8日 · Initial electron microscopy studies of various cyanobacteria reported a dense structure, termed the ‘thylakoid centre’, at the centre of the convergence zone 14, 15, 18. Thylakoid centres...
Ultrastructure of compacted DNA in cyanobacteria by high …
2016年10月12日 · To investigate the three-dimensional (3D) ultrastructure of the compacted DNA in the cell, it is necessary for electron microscopy to overcome two technical issues. One is the observation of a...
Organization and Flexibility of Cyanobacterial Thylakoid …
2013年2月1日 · Kirchhoff et al. used cryo-electron microscopy to examine vitreous sections and found that the grana lumen in Arabidopsis thaliana expands in the light, thereby increasing the lumenal volume and presumably facilitating protein diffusion.
Light-Dependent Electrogenic Activity of Cyanobacteria - PLOS
2010年5月25日 · Here we show that diverse genera of cyanobacteria including biofilm-forming and pelagic strains have a conserved light-dependent electrogenic activity, i.e. the ability to transfer electrons to their surroundings in response to illumination.
S-layers on cell walls of cyanobacteria - ScienceDirect
2002年1月1日 · The history of S-layer research started in 1953, when Houwink (1953), by electron microscopy of a cell section, demonstrated a regular array of uniform macromolecules forming an external surface monolayer on walls of Aquaspirillum sp. Within the next 3 years, observations of metal shadowed preparations brought distinct evidence of an analogous ...
Electron transport in cyanobacterial thylakoid membranes: are ...
2023年4月7日 · A recent study uncovered a 3.2 Å cryo-electron microscopy structure of NDH-1MS, suggesting that the Cup subunits possess a Zn 2+ –arginine coordination similar to an α-type carbonic anhydrase in humans and that CO 2 hydration is coupled with electron transport in the thylakoid membranes in a similar manner to NDH-1L (Schuller et al., 2020).
Cyanobacteria newly isolated from marine volcanic seeps display …
2024年10月29日 · Here, we isolate two novel cyanobacteria with 4.6Mbp genomes, UTEX 3221 and UTEX 3222, from a unique marine environment with naturally elevated CO₂. We describe complete genome sequences for both isolates and, focusing on UTEX 3222 due to its planktonic growth in liquid, characterize biotechnologically relevant growth and biomass characteristics.
