Burkholderia bryophila sp nov and Burkholderia megapolitana sp nov., moss-associated species with antifungal and plant-growth-promoting properties

• A polyphasic taxonomic study including DNA–DNA reassociation experiments and an extensive biochemical characterization was performed on 14 Burkholderia isolates from moss gametophytes of nutrient-poor plant communities on the southern Baltic Sea coast in northern Germany. The strains were classified within two novel species, for which the names Burkholderia bryophila sp. nov. and Burkholderia megapolitana sp. nov. are proposed. The former species also includes isolates from grassland and agricultural soil collected in previous studies. Strains Burkholderia bryophila 1S18T (=LMG 23644T =CCUG 52993T) and Burkholderia megapolitana A3T (=LMG 23650T =CCUG 53006T) are the proposed type strains. They were isolated from Sphagnum rubellum and Aulacomnium palustre, respectively, growing in the ‘Ribnitzer Großes Moor’ nature reserve (Mecklenburg-Pommern, Germany). All moss isolates of both novel species showed antifungal activity against phytopathogens as well as plant-growth-promoting properties.
