Bacteria For Better Ice Cream And Artificial Snow No Longer Depends On Trek To Poles

 Perhaps we can one day publish an article with a similar title, stating, "bacteria for better biogas digestors and urban waste management no longer depends on trek to poles" -- that is, once we have proven that the psychrophiles themselves have commercial potential.
ScienceDaily (Oct. 1, 2006) The search for a type of bacteria that creates better ice cream and artificial snow has suddenly become a lot easier, thanks to a discovery by Queen's University biologist Virginia Walker.

Here are the quotes of relevance to our project: "The new technique involves the formation of an "ice finger" to select for bacteria that will gather on the surface of the ice. Incorporating bacteria into slowly grown ice is based on a method used to purify antifreeze proteins, called ice affinity selection..."Our findings will help to decrease the... See More costs involved in further discovery of such bacteria, since scientists will no longer need expeditions to the poles in order to isolate the bugs," she says. "Now they can find them in their own back yards."

Can we explore "ice affinity selection" for our work in the cold mountains of Tanzania trying to use biogas to stop cold season deforestation?

(The study was funded by a Queen's Research Chair and the Natural Sciences and Engineering Research Council of Canada (NSERC). Does anybody on our team know Queen's biologist Virginia Walker?)

Would depend on what grows "on ice" versus what grows in a low temp. From what I can tell hear the bacteria the queens people found a few years back "interacts with ice"

a concentrated growing surface for cold loving bacteria!
