“…Moreover, ASVs belonging to the fermentative family Prevotellaceae and the genus Caproiciproducens were observed in higher abundance in the anaerobic incubation in the later stages of the experiment. Prevotella is associated with glycan degradation 37 , whilst members of the genus Caproiciproducens can produce acetic acid, butyric acid, caproic acid, lactic acid, and H 2 as metabolic products 38 , 39 . In addition, ASVs assigned to Acidaminococcaceae, which use numerous amino acids as their carbon sources, were detected in the leaf biofilms from anaerobic assays.…”

Biofilms are important in the natural process of plant tissue degradation. However, fundamental knowledge of biofilm community structure and succession on decaying leaves under different oxygen conditions is limited. Here, we used 16S rRNA and ITS gene amplicon sequencing to investigate the composition, temporal dynamics, and community assembly processes of bacterial and fungal biofilms on decaying leaves in vitro. Leaves harvested from three plant species were immersed in lake water under aerobic and anaerobic conditions in vitro for three weeks. Biofilm-covered leaf samples were collected weekly and investigated by scanning electron microscopy. The results showed that community composition differed significantly between biofilm samples under aerobic and anaerobic conditions, though not among plant species. Over three weeks, a clear compositional shift of the bacterial and fungal biofilm communities was observed. The alpha diversity of prokaryotes increased over time in aerobic assays and decreased under anaerobic conditions. Oxygen availability and incubation time were found to be primary factors influencing the microbial diversity of biofilms on different decaying plant species in vitro. Null models suggest that stochastic processes governed the assembly of biofilm communities of decaying leaves in vitro in the early stages of biofilm formation and were further shaped by niche-associated factors.
