a Identification of phospholilpases in the six Collimonas genomes with PFAM signatures of the different phospholipase groups. b Identification of peptidases in the six Collimonas genomes as inferred from MEROPS 9.12 database. c Extracellular protease activity of Collimonas strains Ter331, Ter6, Ter91, Ter291, Ter10 and Ter282. A halo indicates extracellular protease production. d Siderophore production of Collimonas strains Ter331, Ter6, Ter91, Ter291, Ter10 and Ter282 plated on a CAS plate. An orange halo indicates of siderophore production. Gene clusters involved in iron acquisition in Collimonas strains. Five loci are presented: (e) Ornibactin locus. Underneath the genes are the module and domain organization of orbI and orbJ. The domains are as follows: C, condensation; A, adenylation; T, thiolation; and E, Epimerization. Underneath the domains are the amino acids that are incorporated into the peptide moiety. The number associated with the amino acid refers to the position of the amino acid in the peptide chain. f ftr _bcc ABCD locus. g bfr (bacterioferritin) encoding gene and adjacent genes bfd and tonB-exbB-exbD cluster. h fecIR operon. i hmu operon (or bhu Burkholderia haem uptake operon)
