Two lactic acid bacteria named Z40 and Y33 were selected from 98 isolates from traditional fermented fish products,both of them exhibited excellent characteristics in growth speed,acid production and salt-tolerance.And they were identified as Lactobacillus plantarum by 16S rRNA sequencing analysis.The results from the fermented surimi showed that Lactobacillus Z40 could result in a rapid pH decrease and suppression in the increase of total volatile base nitrogen(TVB-N).
