Changes of acidic electrolyzed water on intestinal microflora diversity of Penaeus vannawei during storage

Intestinal microflora was considered as one of the major sources to cause the corruption of aquatic products. As a new- type environmental disinfectant, acidic electrolyzed water( AEW) had gradually been applied to control the security of aquatic products,which was receiving more and more attentions due to its efficient broad-spectrum sterilization. In this paper,PCR-DGGE technology was used to analyze the variation of intestinal microflora diversity in Penaeus vannamei stored at 0℃,4℃ and 25℃,which were treated by tapwater( TW) and AEW, respectively. Compared with TW group, samples under AEW showed a decreasing diversity of intestinal microflora during storage,which indicated that intestinal microflora diversity was significantly affected by AEW. The results would be used to provide a theoretical reference for the security of aquatic products.
