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 diferent 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 monospecifc avocado plantation. Soil-substrate mixes were evaluated for 52 weeks to evaluate organic matter decay and the carbon-to-nitrogen ratio. Amplicon-based high-throughput sequencing from internally transcribed spacer (ITS) analysis revealed signifcant diferences in fungal communities widely dominated by Fusarium sp. and Clonostachys sp.; however, less represented taxa showed relevant shifts concomitantly with organic matter content drops. Trophic guild assignment revealed diferent behaviors in fungal communities between treatments over the 52 weeks, suggesting distinct preconditioning of fungal communities in these environments. Overall, the results lead to the identifcation of promising degradation moments and inoculum sources for further consortia enrichment or bioprospecting efforts.
