In this work, for the first time, the ability of non‐pathogenic bacterial members of the recently discovered genus Massilia to accumulate polyhydroxyalkanoates (PHAs) using glucose or starch as C and energy sources, has been reported. The highest PHAs yields were obtained when glucose was substituted by starch in the culture medium, being Massilia lutea the best producer (1.25 g/L). NMR analyses demonstrated that the PHAs obtained were PHB in spite of the C source used. These results become Massilia strains attractive candidates for use in the production of biopolymers from renewable carbon sources, but further research is needed to understand the processes involved in PHA synthesis and accumulation.
