The planctomycete Stieleria maiorica Mal15^T employs stieleriacines to alter the species composition in marine biofilms.

ABSTRACT: Bacterial strains of the phylum Planctomycetes occur ubiquitously, but are often found on surfaces of aquatic phototrophs, e.g. alga. Despite slower growth, planctomycetes are not outcompeted by faster-growing bacteria in biofilms on such surfaces; however, strategies allowing them to compensate for slower growth have not yet been investigated. Here, we identified stieleriacines, a class of N-acylated tyrosines produced by the novel planctomycete Stieleria maiorica Mal15^T, and analysed their effects on growth of the producing strain and bacterial species likely co-occurring with strain Mal15^T. Stieleriacines reduced the lag phase of Mal15^T and either stimulated or inhibited biofilm formation of two bacterial competitors, indicating that Mal15^T em
