Abstract
|
|
|
A bacterial strain C8-2, which can rapidly degrade a triazole fungicide difenoconazole, was isolated from an agricultural soil.
The genome of strain C8-2 was sequenced and compared with its non- difenoconazole-degrading relative, Sphingomoans histidinilytica UM2 T . The OrthoANI value between the two strains was 99.3% thus strain C8-2 was identified as S. histidinilytica.
The genome of strain C8-2 is composed of one chromosome and one plasmid, with a total size of 5,758,685 bp, a G + C content of 67.2%, 5,393 coding genes (CDS), 114 pseudogenes and 59 RNA genes. Strain C8-2 harbors seven aromatic ringhydroxylating dioxygenases not found in strain UM2 T , and two of them showed high amino acid sequence identities (more than 96%) with the angular dioxygenases previously reported to hydroxylate the diphenyl ether group of 3-phenoxybenzoate, yielding 3-hydroxybenzoate and catechol.
