Foodie TWiM reveals that bacteria in human saliva are major components of Ecuadorian indigenous beers, and an unusual E. coli that produces atypical light cream-colored colonies in chromogenic agar.

The TWiMmers get cozy with symbionts: bacteria that allow a giant shipworm to oxidize sulfur, and algae that live within salamander cells.

The microbophiles investigate the ratio of bacterial to human cells in our bodies, and how placing solar panels on a bacterium enables it to carry out photosynthesis.
