Bioluminescence production and bacterial growth of Photobacterium sp. strain MIE in luminescence media over time. The isolate was grown in luminescence media and incubated in an orbital shaker (100 rpm) for 28 hours at room temperature. Bioluminescence production (black circle) and bacterial growth (circle) were determined using Beckman Counter DTX 800 multimode detector. The error bars represent the mean ± standard deviation of three replicates.
