Identification of Brevibacterium flavum genes related to receptors involved in bacteriophage BFK20 adsorption.

•A B. flavum library of BFK20 phage-resistant transposition mutants was prepared.•The phage resistant phenotype of B. flavum mutants was confirmed by cultivation.•The phage-resistant mutants showed decreased phage adsorption, less than 20%.•Phage sensitivity was restored in two mutants by trans-complementation.•Genes involved in the BFK20 receptor syntheses were identified.
