Article Title: Fungal duo isolated from toxic lake produce novel antibiotic
Summary: In Montana there is an abandoned mining pit called Berkeley Pit. Since it was abandoned in 1983 water has leaked in and make it into a toxic pool with a pH of 2.5. It is so toxic that thousands of snow geese died last winter after they landed in it. However microbes love the pit. Two scientist from the University of Montana Andrea A. Stierleand and Donald B. Sterile who have been studying the fungus in the lake have found that two Penicillium fungus together make a new antibiotic. The antibiotic isn’t really a super new shape but it seems to act differently from know antibiotics.
Connection: Antibiotics we learned we discovered from a penicillin fungus by Alexander Fleming, so I thought it was really cool that we still find antibacterials like that. Could it be that fungus are adapting their antibacterials to fight resistant bacteria? This article also connects to the section on what bacteria use as energy sources, as finding life in an inhospitable place like an abandoned mining pit with pH2.5 is incredible and show how microbes can adapt to use almost anything.
Critical Analysis: The article doesn’t give much on the antibacterial agent it’s self, however it does provide us with a picture of the its chemical structure and a link to the article that the scientists published. The purpose of the post must have been to inform the public of a new discovery in science and I think it does this very well. How the article starts by describing the location of the discovery really draws readers and helps the mission of the article.
Question: We have learned a bit about how bacteria survive in inhospitable places like this pit, but how do fungus do it? How do fungus deal with low pH and high concentrations of heavy metals? Also what do the fungus use as an energy source?
