A great demand for prebiotics is driving the search for new sources of fructo-
oligosaccharides (FOS) producers and for FOS with differentiated functionalities. In the
present work, FOS production by a new isolated strain of Aspergillus ibericus was evaluated.
The temperature of fermentation and initial pH were optimized in shaken flask to yield a
maximal FOS production, through a central composite experimental design. FOS were
produced in a one-step bioprocess using the whole cells of the microorganism. The model …
