High similarity in the microbiota of cold-water sponges of the Genus Mycale from two different geographical areas
Sponges belonging to genus Mycale are common and widely distributed across the oceans and represent a significant component of benthic communities in term of their biomass, which in many species is largely composed by bacteria. However, the microbial communities associated with Mycale species inhabi...
