Serratia proteamaculans swim on the hyphae of the fungus Mucor lanceolatusBENJAMIN WOLFEThe cheese rind bacteria Serratia proteamaculans follow physical networks—microscopic “highways” created by filamentous fungi—to swim in the liquid layers on the fungal branches. This interaction could play a major role in shaping the composition of microbiomes, researchers say.
