(Phys.org) —In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous ...
In the paste of Roquefort and on the surface of Camembert, the microscopic filamentous fungi Penicillium roqueforti and Penicillium camembertii are responsible for the formation of a greenish-blue mould in the former ...
