Annual dynamics and metagenomics of marine vesicles: One more layer of complexity in the dissolved organic fraction

Limnology and Oceanography, EarlyView.
Abstract Despite the role of extracellular vesicles (EVs) in genetic and biogeochemical exchange in the ocean, there is a notable dearth of studies delving into the seasonal annual dynamics of EVs in uncultured microbial communities. Here, quantitative data from the oligotrophic Mediterranean Sea revealed that EVs mL−1 ranged from 104 to 106 throughout

Assessment Method for Leaf Litters Allelopathic Effect on Cyanobacteria [PDF]

, 2005
A new bioassay technique combining leaf disk and softagar over-layer methods was developed to investigate the allelopathic effect of deciduous leaf litters on the growth of cyanobacteria ( Microcystis aeruginosa Kütz.).

Temperature‐dependent growth and activity in a globally distributed nitrogen‐fixing haptophyte

Limnology and Oceanography, EarlyView.
Abstract Dinitrogen (N2)‐fixing microorganisms play a crucial role in supplying nitrogen (N) to the oceans by converting atmospheric N2 into bioavailable N. N2 fixation was thought to be limited to warm oligotrophic ocean waters, but the association between the N2‐fixing UCYN‐A cyanobacterium and specific haptophytes, including Braarudosphaera ...

Ecogenomics and limnological dynamics of a new Thiocapsa species blooming in the whole water column of a karstic lake

Limnology and Oceanography, EarlyView.
Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...

Metamaterial Sensing of Cyanobacteria Using THz Thermal Curve Analysis

Biosensors
In this study, we perform thermal curve analyses based on terahertz (THz) metamaterials for the label-free sensing of cyanobacteria. In the presence of bacterial films, significant frequency shifts occur at the metamaterial resonance, but these shifts ...

Design of Engineered Living Materials for Martian Construction [PDF]

arXiv
As the next step in extraterrestrial exploration, many engineers and scientists around the country revealed their intense interest to enable multiplanetary human life, including colonizing Mars. This study proposes that architecture on Mars can be realized by a synthetic lichen system, composed of diazotrophic cyanobacteria and filamentous fungi, which
