Degradation activity of fungal communities on avocado peel (Persea americana Mill.) in a solid-state process: mycobiota successions and trophic guild shifts.

To explore the capability of soil mycobiota to degrade avocado peel waste and identify relevant successions and trophic guild shifts, fungal communities from three environments with different land uses were evaluated in a solid-state process. Soil samples used as inoculum were collected from a pristine mature tropical forest, a traditionally managed Mayan land, and an intensively managed monospecific avocado plantation. Soil-substrate mixes were evaluated for 52 weeks to evaluate organic matter decay and the carbon-to-nitrogen ratio.

Diversity and Interactomics of Bacterial Communities Associated with Dominant Trees During Tropical Forest Recovery.

Bacterial communities have been identified as functional key members in soil ecology. A deep relation with these communities maintains forest coverture. Trees harbor particular bacteriomes in the rhizosphere, endosphere, or phyllosphere, different from bulk-soil representatives.
