FIG. 3.

Influence of culture conditions on the growth, production of pigment, and antibacterial activity of Phaeobacter strain 27-4 and Silicibacter sp. strain TM1040 in MB at 25°C. The data represent the mean of duplicate cultures (error bars represent standard deviations). (A) Growth was measured by plate counts. □, shaken culture of Phaeobacter strain 27-4; ○, static culture of Phaeobacter strain 27-4; ▿, shaken culture of Silicibacter sp. strain TM1040; ▵, static culture of Silicibacter sp. strain TM1040. (B) Pigment formation, as measured by absorbance at OD₃₉₈. (C) Antibacterial activity represented by the zone of inhibition (in millimeters), as determined by using the well diffusion assay with V. anguillarum.
