The current context of land restoration and increasing the quality of urban ecosystems represent a challenge in the areas where historical pollution with heavy metals is present. The aim of this paper is to show the presence of adaptative mechanisms in the functional microbiome of 5 urban soils after a phytoremediation process. Total activities revealed that 3-7 times increase in the activity is visible in the first 72 hours of incubation and is almost double after 96 hours. This indicates an adapted microbiome to heavy metals conditions and its ability to develop as a community. An in-depth
analysis reveals that carbohydrates and carboxylic acids were the most prominent guilds from the community, but with a distinct functional signature in each of the analyzed sites. Interestingly, polymers, amino acids and amines/amides guilds which represent almost 40% of the activity reported to the entire community, even though these guilds have a reduced functional profile. The results indicate that plant presence in polluted ecosystems represents a factor that enables the recovery of functional microbiome and maintenance of a high activity.
