Fig 1. Serial dilution and drop plates.

Fig 1

Plate “A”: Representative example of L. plantarum control (grown in sulfite free media) utilized for drop plate counts at 6 hours, in sulfite free media. Plate shows four replicates of dilutions from 10−3 to 10−5, 10μl/drop. Section labels (3, 4 and 5) correspond to dilution factors. Plate “B” Representative example of L. plantarum test plates (grown in media containing 10–50 and 1000- 2000ppm NaHSO3). Plate shows four replicates of dilutions from 10° to 10−3, 10μl/drop. Section labels (0,1,2,3) correspond to dilution factors.
