The main constituents of plant cell walls are celluloase, hemi-cellulose, and pectin, which are degraded and absorbed by microorganisms through complex and effective processes in herbivore rumen. Rumen microorganisms are extreme anaerobes, including fungi, protozoa and bacteria, and the breakdown of fibrin is mainly responsible for bacteria and fungi. However, most of these microorganisms are not well known because they are difficult to cultivate. Among the ruminal microorganisms known to date, bacteria that are mainly involved in digesting plant cell walls include Fibrobacter succinogenes), luminometer Caucus Playa Pacifica beret Enschede (Ruminococcus flavefaciens), luminometer Cocu live bus (Ruminococcusalbus), Libby brick Booty avoid debris Sol Bence (Butyrivibrio fibrisolvens), oil cake Te Solarium cellulite with a brush Bence (Eubacterium The bacteria belonging to the genus cellulosolvens), frame Beam telra (Prevotella), and some of Clostridium (Clostridium) have been identified. To date, most microbial DNA in the digestive organs of cows, rabbits, and kangaroos, or the metagenome (referred to as the total DNA of environmental microorganisms) has been studied to identify the most abundant enzymes in the rumen, A number of glucanases and cellulosome complexes have been identified through this process.

As a result, Ad was determined to use 5 units of HindIII and 2.5 units of Lq (Fig. 1). The partially cleaved DNA fragments were clipped from 10 kb to 50 kb using the Pulse-Field Gel electrophoresis method, from which the insert DNA fragments were again prepared. The prepared DNA was subjected to terminal smoothing reaction and ligated to the pCC1FOS vector by ligation reaction. After the ligation reaction, it was transformed into DH5alpha E. coli by electrical shock method to construct a gene bank. In order to confirm the average insertion size of the constructed fosmid gene bank, NotI enzyme treatment was performed and it was confirmed by electrophoresis that 30 kb for Ad and 31 kb for Lq (FIG. 2). For each of these, 150 plates of 384 well plates were inoculated on cryopreservation media and stored in a cryogenic freezer (-70 ° C).

The extracted plasmid DNA was averaged 220 bp in length using an Ion Personal Genome Machine (PGM) 100 times more shotgun sequencing data. The resulting data was converted to fasta format and assembled using the Newbler 2.5 de novo assembler program. A total of three consensus sequences were constructed, and a total of 34,870 bp of metagenomic sequence information was obtained with a length of 22,495 bp, 9,103 bp, and 3,272 bp, respectively.
