Notes.

^aH/C ratio is the ratio of the hydrolytic zone diameter vs. the colony diameter of a colony on the plate.

^aInhibition ratio (%) was calculated by using control activity minus the relative activity of a sample with an inhibitor and the activity of a sample without any inhibitor was taken as a control (%).

PMSF

phenylmethylsulfonyl fluoride

OP 1

10-phenanthroline

P-A

pepstatin A

Pocillopora, Porites, Platygyra, Turbinaria, Faviia, Acropora, Montipora were represented by A, B, C, D, F, L, Q.
