Table 4 Amino acid (AA) profile of mixed microbial biomass protein of C. utilis and B. lactofermentum in beet pulp containing mixed substrate medium in a 75-L fermentor (working volume 50 L). Fermentation product containing unutilized beet pulp, cell mass and fermentation broth was dried with hot air. The dried test samples were hydrolyzed with HCl and analyzed using an automated amino acid analyzer

From: Production of microbial biomass protein from mixed substrates by sequential culture fermentation of Candida utilis and Brevibacterium lactofermentum
