“…All isolated fungi were screened on Mineral salt agar medium supplemented with (0.50 g/l) as a sole carbon source. After incubation for ive days, the precise zone diameter was measured for each fungal colony (Alhazmi et al, 2018). Also, PHB metabolizing in shake lask experiments were conducted in 250 ml Erlenmeyer lasks containing 50 ml of the basal Mineral salt PHB medium (pH, 7) which contained (g/l): PHB (0.5), KH2PO4 (0.7), K2HPO4 (0.7), MgSO4 (0.7), Yeast extract (2.5), Glucose (1), NaCl (0.005), FeSO4 (0.002) and ZnSO4 (0.007).…”
