Characterization and Molecular Study on Polyhydroxybutyrate Produced from Rhodococcus equi
Many soil samples were collected from different places and screened for PHA production by Sudan Black B stain. Twenty isolates had a positive result for Suddan Black B stain. The results were confirmed by staining the viable colonies with the selective stain Nile Red; three isolates gave positive results. One isolate with a more pink fluorescent with Nile Red stain was selected for the present study.
