Strains sequenced in this work are indicated by gray shadings. 9628 refers to J. agaricidamnosum, 1522 to J. lividum, 23865 to D. phyllosphaerae and 16928 to D. zoogloeoides. Violacein (μg/ml) was extracted after growth for 24 h in R2A. Amylolytic and proteolytic activities were measured after 72 h of growth on plates and lipolytic activities after 144 h of growth on solid media containing starch, skim milk, or tributyrin. Activities were recorded as diameter of clearing zones around individual colonies. Chitinolytic activity was determined after 1 week of growth in M9 lacking glucose and supplemented with chitin. +, enzymatic was observed; ++, strong activity; +++, very strong activity; (+), weak activity; –, no activity observed, data are mean values of at least three independent biological test; ± indicates the standard deviations.
