Marine bacteria shift between lifestyles to get the best resources — ScienceDaily


To stay, or not to stay? When it comes to nutrient resource patches, researchers from Japan and Switzerland have discovered that marine bacteria have a knack for exploiting them efficiently, timing movements between patches to get the best resources.

In a study published this month in Proceedings of the National Academy of Sciences, U.S.A., researchers from the University of Tsukuba and ETH Zurich have revealed that marine bacteria optimize nutrient uptake by switching between dispersal and resource exploitation.

Heterotrophic bacteria (i.e., those that cannot produce their own food, instead obtaining nutrition from other sources of organic carbon, such as plant or animal matter) are the main recyclers of dissolved organic matter (DOM) in the ocean.
