A preliminary study on fermentations of poly-floral and date palm pollens by their native and complex LAB flora in selective medium indicates the succession of different LAB major genera (enterococci, lactobacilli, pediococci/leuconostocs and streptococci/lactococci) with shared growth pattern and height bacterial density (6.28- 7.5, 6.86-7.54, 6.20-7.20, and 5.60-6.80 Log10CFU/mL respectively). Synergistic effect between bacterial groups was observed and antagonism was another phenomenon (at least by lowering pH, 3.46-4.0) influencing the dynamics of LAB population during laboratory scale pollen fermentation.
