Un approccio alla costruzione di comunità di biofilm multispecie dal suolo della rizosfera

Overview

This study presents a standardized procedure for establishing synergistic multispecies biofilm communities derived from rhizosphere soils. The protocol aims to advance synthetic biobacterial communities, transitioning the focus from single-strain to community-level applications as potential second-generation biofertilizers.
