A pilot process of solid state fermentation from sugar beet pulp for the production of microbial protein

The bioconversion of sugar beet pulp (SBP) into microbial protein by the process of solid state fermentation (SSF) was studied. Two SSF reactors (each having overall dimensions of 17.6 x 3.6 x 2.0 m) with appropriate control systems were constructed. This pilot plant has a maximum working capacity of 50 metric tons (20% dry metter). The production strain used was Aspergillus tamarii 827, which was isolated by our laboratory. The protein content of the products amounted to 22.4% in 48 h.
