摘要：

The combined production of biomass, hyaluronic acid (HA) and lactic acid (LA) in a glucose fed-batch system was studied. The complex culture media used were formulated with commercial and residual peptones from fish by-products. In all cases, fed-batch fermentations increased the productive period of HA and LA. Tryptone led to the highest productions but with the peptones from shark by-products similar LA concentrations and prominent HA levels were reached. Moreover, with this residual peptone higher molecular weight of HA were achieved. On the other hand, the equations proposed adjusted with accuracy and high statistical robustness the experimental kinetic profiles. (C) 2008 Elsevier B.V. All rights reserved.
