Abstract
Solid state fermentation (SSF) systems have been studied for several processes of biomass and metabolites production. Heterogeneity of substrate represents a serious problem in physiological studies to characterize solid state cultures. Thus, comparison of liquid, surface and solid state cultures is difficult to carry out. With the use of an inert support and the same culture medium, it is possible to evaluate the type of culture for growth and glucose consumption in different culture systems. In this work, amberlite IRA 900 and a minimal culture liquid medium were used to study growth of Aspergillus niger. This system allowed accurate evaluation of biomass and sugars. Glucose utilization and growth were less affected in solid state and surface cultures than in the submerged culture at high levels of glucose.
