Black truffle-associated bacterial communities during the development and maturation of Tuber melanosporum ascocarps and putative functional roles.

abstract：:Iron is the most abundant redox-active metal in the Earth's crust. The one electron transfer between the two most common redox states, Fe(II) and Fe(III), plays a role in a huge range of environmental processes from mineral formation and dissolution to contaminant remediation and global biogeochemical cycling. It has ...
