Crossing the River


July 29, 2018

Two weeks ago I made my way to the Vermilion River, something I do less often than I used to now that we are living back in town. The river still charms me, I’m happy to say, and I was in special good luck July 14 because the river’s water level was low and its banks embellished with iridescent patches of Leptothrix discophora. When the water is low, I get to wade across to the other side, where I usually can find more colonies of my favorite bacterium (photos to come). The wade itself is a treat, though, and I love seeing the ripples filled with sunshine at my feet.

The shale along the shore of the Vermilion River fascinates me no matter how many times I see and photograph it. It’s especially appealing when decorated with leaves.

 


Evidence of Sulfur Bacteria in the Vermilion River


October 21, 2014

I saw something at the edge of the river Saturday, September 27, that I’d never seen before. Checking my hunch with Norrie Robbins, my knowledge source for all things microbial, I learned that this white threadlike formation is evidence of sulfur-oxidizing bacteria. The black stuff around the edges shows the presence of sulfur-reducing bacteria. Since the shale in this area is replete with pyrite (fool’s gold), and pyrite is made of iron and sulfur, it should not have been a surprise.
