The incomplete degradation of bio-based and biodegradable plastics (BBPs) in soils causes
multiple threats to soil quality, human health, and food security. Plastic residuals can interact with
soil microbial communities. We aimed to link the structure and enzyme-mediated functional traits of
a microbial community composition that were present during poly (butylene succinate-co-butylene
adipate (PBSA) decomposition in soil with (PSN) and without (PS) the addition of nitrogen fertilizer
((NH4
)2SO4
). We identified bacterial (Achromobacter, Luteimonas, Rhodanobacter, and Lysobacter) and
fungal (Fusarium, Chaetomium, Clonostachys, Fusicolla, and Acremonium) taxa that were linked to
the activities of ß-glucosidase, chitinase, phosphatase, and lipase in plastic-amended soils. Fungal
biomass increased by 1.7 and 4 times in PS and PSN treatment, respectively, as compared to nonplastic amended soil. PBSA significantly changed the relationships between soil properties (C: N
ratio, TN, and pH) and microbial community structure; however, the relationships between fungal
biomass and soil enzyme activities remained constant. PBSA significantly altered the relationship
between fungal biomass and acid phosphatase. We demonstrated that although the soil functions
related to nutrient cycling were not negatively affected in PSN treatment, potential negative effects
are reasoned by the enrichment of plant pathogens. We concluded that in comparison to fungi, the
bacteria demonstrated a broader functional spectrum in the BBP degradation process
