Beer and Bacteria to be used in Toxin Cleanup

GospelHead821 writes "According to this article in Popular Science, a chemistry student at the University of Tulsa is driving research into use of toxin-munching "sulfate-reducing bacteria" (SRBs) to help cleanup toxic, solid effluent from abandoned zinc and lead mines near her home. Where does the beer come in? Apparently, it has proved an excellent food source for the bacteria and helps to extend the lifespan of the normally short-lived SRBs by several months. Currently, the procedure is in the testing phase, with models being employed to simulate the conditions that would be present in a large-scale detoxification plant, which in turn, is based on the natural wetlands from which these bacteria hail."

      You are correct, there are certain types of bacteria that have the right enzymes to break down hydrocarbons into units the bacteria can actually use as food/cell-building chemicals.

      The only problem with them is that like almost all bacteria, they are UV sensitive, so they were most effective at night and under the oil slick. In the morning, most of the colonies would get wiped out by the sunlight.

      These bacteria are slightly different in that they seem to be breaking down not hydrocarbon (oil) waste, but heavy metal waste. What I couldn't glean from the article was what the bacteria are doing with the waste once they injest it. Yes, they've broken it down, but you have to atomistic/matter conservation here, so the toxic zinc and other heavy metals have to go somewhere. Since beer is needed to feed the bacteria, they're obviously not using the heavy metals to generate more of themselves or create some special zinc-containing enzyme. My guess is that the bacteria break down the toxic form of the zinc/heavy metals and turn it into something easier for the environment to handle. However, I have no idea here what those bacteria are doing with it. I wish the popular science article had been more verbose in scientific content.

      You are correct. If I remember correctly, this bacteria was patented by the company that developed it. Others wanted to copy the bacteria and challenged the patent, and eventually the Supreme Court ruled that you could patent an organism under the U.S. Patent law. This led to the rush to patent every human gene that a start-up lab could get their hands on, by only speculating what possible uses the gene might have.

  23. Where do the heavy metals go? by caesar-auf-nihil · · Score: 5, Interesting

    While this bioremediation technology looks real cool at first glance, and creates lots of beer jokes, I can see one potential flaw with it, unless I'm missing something. The flaw is that all that toxic lead and zinc have to go somewhere, even if the bacteria chew it up and remediate the soil. So where are the heavy metals going?

    My guess is that they are taken up by the bacteria and somehow locked into a protein structure, putting the metal in the bacteria cell and not in the ground. Okay fine, you've gotten the toxic metal out of the ground and into the bacteria, but now what? If the bacteria are just left in the soil, they'll eventually decay and rather than having large chunks of zinc and lead laying around, you'll have atomisically dispersed metal all over the place.

    I wish the popular science article had been more specific or verbose in how the whole thing would be engineered. My guess is that they'll have to somehow separate the soil from the bacterial colonies and burn the colony to collect the pure metal. The metal can then be recycled or stored safely. Separating the soil from the bacteria though is going to be very difficult.

    I remember a similar technology that used plants to remove mercury from contaminated water streams rather than using bacteria. The scientists took a swamp plant that naturally had an affinity for mercury ions, and selectively bred/genetically engineered the plants to have even more affinity for the toxic mercury ions. The plants roots when then dangle in the waste streams, removing the ions and moving it to the leaves (natural defense mechanism as it turns out - animals and some bugs don't want to eat mercury-toxic leaves). After awhile the plants could be "harvested" and burned, where the mercury metal could then be collected, distilled, and recycled.

    Given the sucess of the above approach (its now used by several companies that sometimes have mercury metal in their chemical waste streams) I'm surprised that a similar approach isn't used here.

    If any of you out there know how this whole process works, or where these metals are going, please let me know via this forum, I'm very interested in finding out.

Separating the soil from the bacteria though is going to be very difficult.

      According to the article, an artificial wetland will be constructed and the bacteria will be seeded into the layer of organic material at the bottom of the water. Runoff from the mines will be directed into the wetland and the bacteria will bind the metal. The article doesn't say, but the presumption is that the metal will remain trapped in the organic layer, and it should remain there even after the bacteria die, especially after it gets covered with new layers of sediment and organic material.

      The main goal isn't necessarily to remove the metal from the environment completely -- this is mining country; the presence of metals in the environment is why they began mining there in the first place -- but to keep it contained and out of the groundwater. The main obstacle I see is keeping mine runoff confined to the wetland and keeping the wetland itself well-supplied with beer and SRB. How long does Harris propose to keep feeding it, anyway?

      Now if only they can do something about the sinkholes, which is a very serious physical danger to the community.

Once the usefull properties of this substance were revealed, a former waste product became a valuable commodity. Maybe one day this kind of recycling will be the norm rather than the exception. But for now, citizens of industrialized countries, and especially America, seem content to throw away wealth in the form of unrealized potential of used goods and byproducts, or outright burn it by spewing it out the exhaust of grossly inefficient SUVs.
