Abstract (EN): The rates were monitored on biomass increase, polysaccharide production and viscosity development of whey broth and a control synthetic broth during fermentation by Rahnella aquatilis and organic acids, lactose, peptides and free amino acids were measured, Growth curves were similar and characterized by maximum specific growth rates of 0.61 h(-1) for whey and 0.63 h(-1) for synthetic medium. The yields of polysaccharide were 0.59 g/g(lactose) for the synthetic medium and 0.56 for whey, Small peptides (<4,000 Da) and most free amino acids in both fermentation media were consumed within 24 h.
