(Phys.org)—Of the many microbes that – like almost all life – require iron, some live in iron-limited environments. What to do? Secrete siderophores, of course: small, high-affinity iron chelating compounds that scavenge ...
A USC-led research team has found that marine microbes with a special metabolism are ubiquitous and could play an important role in how Earth regulates climate.
