Russians Find "New Bacteria" In Lake Vostok

samzenpus posted about a year ago | from the new-germ-on-the-block dept.

Science 147

tverbeek writes "Russian scientists believe they have found a new type of bacteria in the sub-glacial Lake Vostok. From the article: 'The samples obtained from the underground lake in May 2012 contained a bacteria which bore no resemblance to existing types, said Sergei Bulat of the genetics laboratory at the Saint Petersburg Institute of Nuclear Physics. "After putting aside all possible elements of contamination, DNA was found that did not coincide with any of the well-known types in the global database," he said. "We are calling this life form unclassified and unidentified," he added.'"

Re:"life form unclassified" (5, Informative)

Samantha Wright (1324923) | about a year ago | (#43110995)

That's hyperbole, I'm afraid. It's a bacterium, just a very distant cousin. Great for studying evolution, irrelevant to Michael Chrichton. Based on the other bacteria recovered from the borehole sample, its hobbies most likely consist of "feeding on geothermal heat" and "being adapted to an extremely stable, homogeneous environment with no predators or other forms of life," which as a general rule means it's as helpless as the Kakapo [wikipedia.org].

Re:"life form unclassified" (1)

bennomatic (691188) | about a year ago | (#43111167)

I understand the rationale behind the general rule as stated, but is it totally impossible that a strain of this could survive even an extreme change in environment, adapt and thrive to such a degree that it would become a danger to the natives of that environment?

I mean, I know it's more extreme than, say, eucalyptus trees in California or rabbits in Australia, but to write off the possibility completely seems like an exaggerated response.

I was going to be more glib in my response, but your sig implies that you've got some experience with the biological sciences, so my question is sincere.

Re:"life form unclassified" (5, Informative)

Samantha Wright (1324923) | about a year ago | (#43111425)

Based on circumstantial evidence (another species found nearby), the bacterium is a thermophile that depends on geothermal heat for warmth. Because of the way thermophiles evolve, it is pretty much certain that the proteins in this species are non-functional at colder temperatures; the samples collected were either dead or in a deep state of antifreeze-clogged hibernation.

It's also 700 million years (or more!) behind on immune defences, which means it's vulnerable to everything from the toxins that all plants constantly secret all the time to the macrophages in our blood. The immune game is a Red Queen scenario [wikipedia.org]—either a pathogen is at the forefront of innovation, or it's susceptible to the most basic form of detection.

The only environment this could possibly intrude upon is one comparable to its own—maybe a heat vent in another frozen lake. Even if it wasn't a thermophile, it would be dead meat on the surface because of bacteriophages (viruses). To add insult to injury, as far as we know this bacterium has no competitors and is not part of a community, making it highly unlikely that it has any competition or any defences.

Gene retention is like lactose tolerance—if you don't use it, you'll lose it. For animals, this typically takes a few thousand years. For bacteria it happens much more quickly. They're very simple organisms, and they're very good at adapting, but only if they've had time to adjust to their new setting. In this case, every single one of its (probably several thousand) genes has spent millions of years being fine-tuned for the most boring environment possible. It has absolutely no hope.

Re:"life form unclassified" (0)

Anonymous Coward | about a year ago | (#43112451)

"Even if it wasn't a thermophile, it would be dead meat on the surface because of bacteriophages"
I've heard that bacteriophages are very specific about their potential hosts, wouldn't you need a phage that targets other similarly structured bacteria, and this one having diverged some 700mya couldn't those prove to be tricky to come by?

Re:"life form unclassified" (1)

Samantha Wright (1324923) | about a year ago | (#43112551)

If not phages then something else. Protists. Nematodes. If it's really been isolated for this long, it probably has a really slow doubling time; that may be bad enough that predation could overwhelm it.

That being said, though, evolutionary pressure is still key. Viruses are host-specific because the hosts keep changing; an older bacterium is more likely to have exploitable sugar moieties on its surface.

Re:"life form unclassified" (0)

Anonymous Coward | about a year ago | (#43112623)

Oh, absolutely, i'm not disputing that it's extremely vulnerable out in the big bad world, but was curious about just how susceptible it would be to modern phages.
  "an older bacterium is more likely to have exploitable sugar moieties on its surface.", while not making a great deal of sense to me, is very roughly the kind of thing i was curious about, had i been able to express the question without feeling that it looked stupid, it would have been appended to my initial question as an or, thanks.
I shall now spend some time looking stuff up and remaining baffled!

Re:"life form unclassified" (1)

Samantha Wright (1324923) | about a year ago | (#43113003)

Viruses decide what to stick to by looking for unique features on the outsides of cells. Bacteria are more or less all the same on the inside, so once it's in, it's in. Phages have their own reproductive machinery for the most part; they just need a cell to reside in. One of the unique features they can stick to are glycoproteins and glycolipids embedded in the exterior cell wall (a second phospholipid bilayer that surrounds the membrane). To be honest it's fairly likely that these evolve so quickly that no phage would be able to recognize them—i.e., the arms race has moved on—but an exceptionally nonspecific phage might still be able to exploit it, or this old species might have a stump of a more complex carbohydrate tree found on newer species (the opposite of a master key, if you will.) I'm not really a membrane buff, though, so I can't tell you much more than that.

You do know Antarctica was part of the super-continent the dinosaurs inhabited eh? Its also only been frozen for around 25 million years too.

Re:"life form unclassified" (2)

Samantha Wright (1324923) | about a year ago | (#43113245)

Yyyyeah, well... if it was only isolated from the rest of the biological tree for 25 million years, we'd only see about 0.5-1% difference in the 16S rRNA. TFA reported (what I think) is at least 14% difference, which is at least 700 million years. Either all of its relatives died off, or it's been down there at that thermal vent this whole time, only vaguely aware (in an "evolutionary pressures" kinda sense) of the ice around it.

Also, if it was really that nasty, it probably would have "got out" long ago instead of only surviving in the depths of a nearly frozen lake.

Maybe it chills the human body down, and dissipates the resulting negentropy by animating it.

I'm not exactly sure if this invalidates your comment, but Uranus is not believed to have a distinct surface underneath its atmosphere. The most popular model suggests that it just gets denser and denser, culminating in a rapidly-spinning mantle-ocean of water, ammonia, and other gasses long before the actual rocky core.

I don't think it's published yet. TFA mentions "less than" 86% DNA "similarity", which I think was supposed to be 86% 16S RNA homology, in which case, the bacterium has been separated from the nearest known species for at least 700 million years.

I don't know how this stuff works so can only stupidly speculate that it will be interesting to try to follow the mutations this wee beastie underwent to let it survive in its current home, and that it somehow could be interesting if not useful when comparing that to some of its closer cousins on our side of the lake.

Might there be clues that let us make more robust some of our helpful bacteria? Or even clues to help combat some of the 'super-bugs' that are really scary in their resistance to anti-biotics, given the extent of nosocomial infection?

Re:Hope this doesn't go the way of arsenic life (1)

Samantha Wright (1324923) | about a year ago | (#43112561)

There's a good chance it has some neat antifreeze proteins. It's most likely very vulnerable to antibiotics, though; biological war far is an arms race. We can only learn from analysing the enemy and things similar to it.

Re:Welp, game over (2)

Actually, there's a pretty good chance it'll die off before then. It's been isolated for at least half a million years (possibly a lot longer), and their drill bit was contaminated with at least sixteen species of other bacteria. You get the picture—entropy, genies, bottles, et cetera.
