*3.2. Annotation of Carbohydrate-Active Enzymes*

The carbohydrate-active enzymes and carbohydrate-binding modules were annotated using the dbCAN2 Meta server (version 9.0) with default settings [24]. Predictions by at least one of the three algorithms integrated within the server (DIAMOND, HMMER, and Hotpep) were considered sufficient for CAZy family assignments. The relative abundances of CAZymes and PLs were visualized by stacked bar plots and heat maps using the ggplot2 (version 3.3.3) and pheatmap (version 1.0.12) packages in RStudio (version 1.3.1093) with R (version 4.0.3, R Foundation for Statistical Computing) [35,36].
