title: Fiber group sequencing
design: In this study, the Illumina hiseq sequencing platform was used for sequencing. A total of 519605.33 MBP of raw data (raw data) (with an average data volume of 6928.07 MBP) and 517291.29 MBP of effective data (clean data) (with an average data volume of 6897.22 MBP) were obtained after quality control. After single sample assembly and mixed assembly, a total of 14266006467 BP scaftigs were obtained. According to the results of each sample and mixed assembly, the metagenemark software was used for gene prediction, and a total of 18138008 open reading frames (ORFs) (with an average of 241840) were obtained. After redundancy removal, 3236339 ORFs were obtained, with a total length of 1776.95 MBP, of which 1501130 were complete genes, accounting for 46.38%. The non redundant gene set was compared with the micronr library for blastp, and the LCA algorithm was used for species annotation. The proportion of annotation to genera and phyla was 50.35% and 77.19% respectively. Non redundant gene sets were annotated with diamond software with common functional databases (E-value < = 10  5). 72429 (2.24%) ORFs were aligned to cazy database, 1408813 (43.53%) ORFs were aligned to KEGG database, and 1511628 (46.71%) ORFs were aligned to eggnog database. The non redundant gene set was annotated with the resistance gene database (card) (E-value < = 10  30), and 1131 genes were aligned to the card database.
