[Poly-(3-hydroxybutyrate) granules in Bacillus megaterium. Isolation and analysis of associated proteins]. / Gránulos de poli(3-hidroxibutirato) en Bacillus megaterium. Aislamiento y análisis de las proteínas asociadas.

Bacillus megaterium accumulates poly-(3-hydroxybutyrate) (PHB) as a reserve material in intracellular granules. In this work we described a method for the preparation of PHB granules from B. megaterium PV447 and the analysis by polyacrylamide gel electrophoresis of the associated proteins. By comparison with another species a function is proposed for some of these proteins.
