Determination of poly-β-hydroxybutyrate (PHB) production by some mesophilic and thermophilic lactic acid Bacteria

Accumulated poly-β-hydroxybutyrate (PHB) was determined in lactic acid bacteria belonging to the genera Lactobacillus, Lactococcus and Streptococcus. Lactobacilli were grown in MRS broth and the others were grown in Elliker broth medium. Cell biomass was obtained by centrifugation.
