%X The microbial fermentation of protein-rich blue algae for proteases production provides a new way to utilize the blue algae resource.The main factors of the fermentation medium affecting proteases production were studied by Serratia sp.SYBC H via the single factor experiment.The results showed that within the experimental ranges,the optimal carbon source,inorganic nitrogen source,salt and stimulant for Serratia sp.SYBC H proteases production were sucrose,urea,ZnSO4 and Tween 80,respectively.The highest protease activity reached 941 U/mL in the supernatant.The fermentation time is short.Only 18 h is required to reach the maximum protease activity in the supernatant.
