Isolation of Methanobacterium bryantii from a Deep Aquifer by Using a Novel Broth-Antibiotic Disk Method.
Methanobacterium bryantii was isolated from a mixed-culture enrichment of a water sample from a deep aquifer by using a complex growth medium supplemented with antibiotic susceptibility disks to inhibit the growth of non-methanogenic bacteria.
