Table 1 Classification of PBSA and PBS film-degrading fungi on agarose plate based on degradation rates

From: Degradation of biodegradable plastic mulch films in soil environment by phylloplane fungi isolated from gramineous plants

Class-index^a	I	II	III	IV	V
PBSA	12	19	8	12	4
PBS	18	29	5	2	1

^aClass-index: I: 0% degradation, no change in film color; II: less than 25% degradation (breakdown of film periphery), loss of film gloss, or thinning of film; III: 26% to 50% degradation; IV: 51% to 90% degradation; and V: over 91% degradation.
