text: 'Poly-3-hydroxybutyrate (P3HB) is a promising alternative to persistent conventional
plastics, capable of biodegrading within months. However, its microbial-driven
degradation raises concerns about nutrient immobilization and impacts on plant
growth. The biodegradation process occurs in multiple stages, during which shifts
in the microbial community can alter soil properties and influence utilization
of both intrinsic and polymer-derived organic matter. This study employs a novel
approach to investigate how nutrient dynamics during the late stage of P3HB biodegradation
affect lettuce (Lactuca sativa var. capitata cv. Brilliant) growth. Soil-to-sand
mixtures (100_0, 80_20, 60_40, 40_60, 20_80, and 0_100 ratios) were spiked with
P3HB, allowed to biodegrade for eight weeks, and then planted with sprouted lettuce
seeds, which were cultivated for another eight weeks. P3HB addition inhibited
plant growth and root development in all soil-sand mixtures. However, increasing
the sand proportion enhanced plants'' nitrogen content by 13-45 % compared to
100 % soil + P3HB. Depending on the sand-to-soil ratio, P3HB stimulated most enzymes
involved in carbon, nitrogen and phosphorus acquisition. Basal and substrate-induced
respirations were 9-209 % higher under P3HB addition compared to P3HB-free soil,
likely due to an increase in the stabilized soil organic matter fraction. Residual
P3HB analysis revealed that diluting soil with 20 % sand accelerated biodegradation,
despite a decrease in bacterial abundance. In the 80_20 variant, the microbial
community shifted toward higher fungal abundance, 19 % more than in 100_0 soil.
While microbial proliferation was observed, it effect was outweighed by negative
impacts on dry aboveground and root biomass. The highest P3HB biodegradation rate
occurred in the 80_20 variant, underscoring soil texture as a critical factor
in P3HB biodegradation. While microbial communities can degrade bioplastics, this
process may compromise plant nutrient availability and hinder plant growth. '
