The invention relates to the technical field of microorganisms, and particularly discloses a process for producing acrylamide in a rate-controllable manner based on a microbiological method. A controllable rate type acrylamide production process based on a microbiological method comprises the following steps: preparation of a fermentation liquid: firstly, adding a strain into a seed culture medium for culturing to obtain a seed liquid; adding the seed solution into a fermentation culture medium for fermentation to obtain a fermentation solution; preparing a catalyst, namely adding sodium alginate and carrageenan into the fermentation liquor, uniformly stirring to obtain mixed liquor, adding the mixed liquor into a calcium chloride solution, standing for reaction, filtering and washing to obtain the catalyst; hydration: acrylonitrile is added into water, then a catalyst is added, a reaction solution is obtained, a hydration reaction is performed, and an acrylamide hydration solution is obtained; filtering: fil
