Natto is a functional food, but it produces an unpleasant smell during the fermentation process. To eliminate the unacceptable smell, and were used to co-ferment soybeans in this study. The optimal conditions of co-fermentation anaerobic fermentation were: fermentation time 20 h, temperature 35 °C, strain ratio 1:1, and inoculum amount 4%. After optimization, fibrinolytic activity, antioxidant activity, polyphenol content, and γ-polyglutamic acid (γ-PGA) yield of Natto were increased by 15.2%, 10.9%, 29.1%, and 72.3%. It also introduced a wealth of probiotics with lactic acid bacteria up to 1.45 X 10cfu/g. The co-fermented natto had unique fruity and lactic flavor, and high sensory score based on the flavor and sensory analysis. The activity and value of natto have been increased through co-fermentation, making it possible to improve natto.

纳豆是一种功能性食品，但在发酵过程中会产生难闻的气味。为了消除这种难以接受的气味，本研究使用[具体物质1]和[具体物质2]共同发酵大豆。共同发酵厌氧发酵的最佳条件为：发酵时间20小时，温度35℃，菌株比例1:1，接种量4%。优化后，纳豆的纤溶活性、抗氧化活性、多酚含量和γ-聚谷氨酸（γ-PGA）产量分别提高了15.2%、10.9%、29.1%和72.3%。它还引入了大量益生菌，乳酸菌含量高达1.45×10cfu/g。通过风味和感官分析，共同发酵的纳豆具有独特的果香和乳酸风味，感官评分较高。通过共同发酵提高了纳豆的活性和价值，使纳豆品质提升成为可能。
