The present invention relates to a fermented product of a lactic acid fermented with a compound of the present invention and a method for producing the fermented product. More specifically, the present invention relates to a fermented product of a lactic acid fermented with a bifidobacterium bifidum By fermenting first and fermenting it with Lactobacillus saccharum LI033 lactic acid bacteria, it is possible to enhance the activity of protecting nerve cell which inhibits cell damage and death, Fermented lactic acid bacteria having a protective activity and a method for producing the same.The fermented product of the compound mushroom lactic acid bacteria having the nerve cell protective activity and the method for producing the same, comprising the steps of: preparing a compound mushroom extract Binding and diluting the composite mushroom extract to a final 5 bricks Sterilizing the unsheltered and diluted complex mushroom extract at 120 to 125C for 13 to 17 minutes To the sterilized complex mushroom extract was added Bifidobacterium bifidum (BifidobacteriumBifidum)To 2% (v / v) Fermenting the mixed mushroom extract inoculated with Bifidobacterium bifidum at 70 to 74 hours at 35 to 40C Centrifuging the complex mushroom primary fermented product obtained through the primary fermentation step at 3 to 5C and 9,000 to 11,000 rpm for 4 to 6 minutes Sterilizing the centrifuged complex mushroom primary fermentation product at 120 to 125C for 13 to 17 minutes To the sterilized complex mushroom primary fermentation product was added Lactobacillus saccharum LI033 (LactobacillusSakeiSubsp. LI033) at 2% (v / v) Fermenting the complex fermented mushroom primary inoculated with Lactobacillus saccharum LI033 at 35 to 40C for 22 to 26 hours Centrifuging the complex fermented mushroom obtained through the second fermentation step at 3 to 5C and 9,000 to 11,000 rpm for 4 to 6 minutes Sterilizing the centrifuged composite mushroom secondary fermentation product at 120 to 125C for 13 to
