Metagenome of Fe-Mn enrichment culture
To obtain enrichment cultures sample sediments from Fe-Mn layers were put in laboratory bottles (1 L) with culture medium. This medium contains sterile Baikal water, remaining oxygen was replaced by flushing N2 in the bottle. The samples were stored at a temperature of 7 C in refrigerator. After 8 month of cultivation, DNA was extracted by enzymatic lysis, followed by phenol-chloroform extraction. Metagenomic sequencing were performed at the Novogene (Tianjin, China) using the Illumina 2  150 PE protocols on an Illumina NovaSeq 6000 platform
