BACK TO 1f: HOT POTS OF YELLOWSTONE
THE COLLECTION PROCEDURE
the scientists tested the water in a hot pot for temperature and
pH. They used electronic gauges - although when the electronic pH
meter failed, they were forced to rely on good ol' fashioned litmus
the water tested near the desired point of 145 degrees F and pH
3, they drew samples of the water. As
one scientist drew samples, others carefully labeled them and used
notes and digital photos to document where the samples came from.
some of the samples, it was important to keep the Sulfolobus
microbes alive during their long cold trip back to the lab. The
scientists did this by introducing enough calcium carbonate to the
samples to bring the pH closer to neutral (7). As its environment
cools, Sulfolobusloses the ability to prevent acid from
destroying its cell structure.
