Extracellular Polyhydroxyalkanoate Depolymerase by Acidovorax sp. DP5

Table 1

The degradation index based on the formation of clear zone on MSM-P(3HB) agar.

Isolates	Clear zone diameter (); (cm)	Colony diameter () (cm)	DI; ()
DP1	3.80	1.40	2.71
DP2	3.00	0.80	3.75
DP3	2.30	1.00	2.30
DP4	3.85	1.55	2.48
DP5	4.50	0.75	6.00
DP8	3.75	1.50	2.50
DP10	4.45	0.80	5.56
DP12	2.20	2.10	1.05

Cells were grown for 4-5 days at 30°C before the clear zone was formed. Values are mean of two replicates.
Degradation index (DI) is calculated based on clear zone diameter/diameter of colony.
