Bacteria replicate from single origins while archaea and eukaryotes replicate using multiple origins. (ukri.org)
Halophilic3
In addition, often neglected predators such as Haloviruses or Protozoa feeding on halophilic archaea and bacteria are not only described but also evaluated on their impact on microbial communities in three chapters. (biomedcentral.com)
The early findings have led the experts to suggest that halophilic (thriving in salt conditions) prokaryotes, also known as archaea and bacteria, were likely the cause of the brightly colored water," UH said in a news release. (wspa.com)
Using this approach, new DAAO genes were found in the genomes of six strains of extremophilic bacteria, and for the first time in the world, one gene was identified in the genome of halophilic archaea. (actanaturae.ru)

Genes4
In recent years the presence of intron-containing genes has been documented in archaea, bacteriophages, and even some bacteria. (pressbooks.pub)
It is speculated that archaea evolved to become resistant to the antibiotics that some bacteria generated because many genes that distinguish archaea and bacteria are associated with resistance to antibiotics of bacterial origin. (scienceasker.com)
In the archaeon Haloferax volcanii, deletion of all origins or genes encoding initiator proteins leads to the initiation of replication by recombination - strikingly, this also leads to accelerated growth. (ukri.org)
The thermosome (Ths) chaperonin family represents the most salient PHX genes among Archaea. (wikigenes.org)
Methane6
The H2 and CO2 formed are further used by the methanogenic archaea to produce methane. (wur.nl)
Some archaea present in methane-predominant SIBO are responsible for sudden weight gain. (nanosingaporeshop.com)
Archaea began to be studied in the 18th century in Italy, when methane bubbling was observed in Lake Maggiore. (scienceasker.com)
This phenomenon was due to the fact that the archaea at the bottom of the lake synthesized methane gas, which rose to the surface. (scienceasker.com)
When scientific observations showed that plants, mushrooms, algae, and cyanobacteria also form methane in the presence of oxygen, this was initially attributed to enzymatic activities,' Ernst added. (labroots.com)
These steps are part of a process that ultimately leads to methane production in a variety of cell types, including bacteria, archaea, yeast, plant cells, and human cells. (labroots.com)
Microbes2
The idea is that since the surface is solid the microbes can't move around too much, and at any spot where a single cell starts initially, a whole pile of that cell and it's genetically-identical (non-sexually-produced) clone-children will form until it gets big enough to see without a microscope. (bigroom.org)
Archaea are microbes renowned for living in extreme conditions. (ukri.org)
Microorganisms1
Similarly, microorganisms exhibit patterns in relative abundance, distribution, diversity, and traits across space and time, yet it remains unclear the extent to which microorganisms follow macroecological rules initially developed for macroorganisms. (frontiersin.org)
Genome2
National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. (wikipedia.org)
Introns were initially thought to be entirely a feature of the eukaryotic genome. (pressbooks.pub)
Hydrogen1
The company said it will increase its focus on low-carbon bioenergy and also set a target to produce 0.5 million-0.7 million tons a year of low or zero-carbon hydrogen to initially supply its own refineries. (thelarkanachamber.com)
Deletion1
Initially, a pyrF deletion mutant was obtained as a starting point for the construction of further markerless mutants. (univ-brest.fr)
Prokaryotic2
They can be found very early in Earth's fossil records (about 3.25 billion years ago) as both Archaea and Bacteria, and commonly protect prokaryotic cells by providing them with homeostasis, encouraging the development of complex interactions between the cells in the biofilm. (wikipedia.org)
On the other hand, there are two groups of prokaryotic organisms (without a nucleus): bacteria and archaebacteria or archaea. (scienceasker.com)

The denitrification microbiome is initially inhibited due to high nitrate input, then they developed denitrification ability in response to high nitrate concentration. (bvsalud.org)
Clostridioides difficile is an example of an infection that is typically initially caused by antibiotic-induced disturbances of the microbiome," said Licht. (medscape.com)

Life1
Archaea can inhabit this type of extreme environments, where other forms of life are not conceivable. (scienceasker.com)
Domain2
Initially wrongly assigned to GH109 due to the shared N-terminal NAD+ domain. (cazy.org)
While bacteria were the most abundant domain, archaea and eukaryota were more abundant in non-disinfected and disinfected systems, respectively. (biomedcentral.com)
Explain1
This would also explain why archaea evolved to adapt to extreme environments, as they were looking for ecological niches that were not occupied by bacteria. (scienceasker.com)
The Zika virus was initially identified in 1947 in Uganda, where it was originally limited to rhesus monkeys. (interactivebodybalance.com)
Surface2
[8] [5] The first colonist bacteria of a biofilm may adhere to the surface initially by the weak van der Waals forces and hydrophobic effects. (wikipedia.org)
You make a solid (but wet) surface that contains whatever nutrients the microbe (bacteria, archaea, yeasts, mold spores…) you're interested in need, and then you spread a diluted mixture of the microbe on it. (bigroom.org)
