Food is important for survival organisms. Food preservation is an important method preserving food. There are many issues on it, to avoid these problems and reduce side effects when using traditional methods of food preservation. The use of probiotics has been resorted to. Lactic Acid Bacteria (LAB) is among the distinct groups of bacteria as probiotics. It produces many antimicrobial contents, including antifungal. Therefore, secondary metabolites were extracted for some locale LAB isolates (Pediococcus sp., Enterococcus sp. and Lactobacillus sp.) in synergy with aqueous extracts of Syzygium and Cinnamon and Aspergillus niger was treated with these extracts. The results of statistical analysis showed a synergistic antifungal activity of these extracts against A.niger The highest synergistic effect was  of Lactobacillus sp (L2) extract  that synergy with Syzygium extract with a significant difference  at probability 0.05  and it was % 96 with growth area 50.24 mm2 as compared with area growth of control 1674.66 mm2, while the synergistic activity of bacterial extracts with Cinnamon extract were less than with  Syzygium extract. As the highest inhibition against A. niger was reached for Lactobacillus sp (L2) that synergistic with Cinnamon extract, the percentage was %57 with growth area as 706.5 mm2 compared with control.
