Using a clustering algorithm and machine learning, a team of researchers analyzed 15,000 images of nearly 125 Clostridium thermocellum bacteria. The result is data-rich pictures showing the location of cellulosomes. Here, areas in yellow, green, and red show where cellulosomes are clustered on plant biomass particles (shaded in purple). The white rod-like shapes in the left photo are the bacteria. Credit: John Yarbrough, National Laboratory of the Rockies To the untrained eye, they look like blobs blotching the otherwise smooth surface of rod-like bacteria. But if you ask a microbiologist about "cellulosomes," they will likely tell you that those blobs are actually sophisticated cellulolytic machines.…
