So other microbes «denitrify» ecosystems, converting the element back into forms not available for living things.

Your very existence depends on clean water and
so does that of every
other plant, animal and
microbe on the planet.
I used to work down the hall from him,
so I'm sure that some of my enthusiasm for the tiny creatures can be blamed on him, along with USC's out - of - control
microbe - lover Ken Nealson (Shewanella oneidensis is his bug, among
others).
«It also may be possible to modify the test
so that it could be used to detect pathogens
other than viruses, including bacteria, fungi and
other microbes, as well as genes that would indicate the pathogen is resistant to treatment with antibiotics or
other drugs,» said co-author Kristine Wylie, PhD, assistant professor of pediatrics.
So the bacteria evidently form a sort of conductive chain, comprising biological nanowires and possibly pyrite grains embedded in the mud, that allows electrons from the oxidation of hydrogen sulfide and carbon within the sediment to contribute to the reduction of oxygen by
other microbes at the sediment surface.
Some of the
microbes seem to lack a metabolism,
so can not feed themselves and may be reliant on
other species for survival.
He has a postdoctoral student and a graduate student trying to grow the consortium in a laboratory, knowing that the reason he and
other microbiologists failed to do
so in the past is that the
microbes grow extremely slowly.
The
microbes rely on oxygen, carbon and
other nutrients in their deep environment to live, but Røy's team found that carbon is
so limited that the cells respire oxygen 10,000 times slower than bacteria in lab - grown cultures.
The studies open up new opportunities to uncover microbial genomes from
other environments, revealing how
microbes alter global carbon and nitrogen cycles, how microbial metabolism evolved, and how
so many different kinds of
microbes can coexist, says biological oceanographer Paul Falkowski of Rutgers University in New Brunswick, New Jersey.
So for example, if one
microbe is resistant to antibiotics and the
other one isn't, if we let them have sex, maybe one of them will pass the resistance gene on to the
other one and we can figure out where it is by seeing how long it takes for that gene to get from one
microbe to the
other.
Next, studies involving germ - free mice (that is, mice that lack
microbes) and
other research uncovered ties between these
microbes, our
so - called microbiota, and health — with bacteria playing potentially key roles in immunity, obesity, and development.
If
microbes once survived in these pockets on early Earth, they could potentially have done
so on
other planets too, Airo says.
It is even possible that life on Earth may have evolved from life forms ejected from Venus, because pieces of planets were blasted off of each
other much more frequently in the early Solar System by asteroidal and cometary impacts, and
so microbes from Venus could easily have ended up landing on Earth (Sean Henahan, Access Excellence, February 5, 1997; and David Grinspoon, 1997).
In my lab we engineer
microbes so that they can not only synthesize new proteins and
other molecular building blocks, but also orchestrate the assembly of those building blocks into higher order structures and functional materials.
In
other words, the
microbes that cause food to rot need water to live,
so if the burger loses its water and is kept in a dry place, it's not going to rot.
So we're just that
other 10 %, a shell providing a habitat for this mass of
microbes.
The things you're working with like dirt and
microbes and plant compounds, they really run the gamut, but what lets you run the line between kids» stuff and adults» stuff when
so many feel they're just one or the
other?
So, just as our body protects itself with the immune system against
microbes or viruses, it also tries to protect itself with
other systems — and the endocannabinoid system is one of them.
Others may become
so over time, as
microbes catch up with those who would tame them.
