Notwithstanding the value of spontaneous sourdough fermentation,
especially in the case of traditional baked goods production,
the use of selected starters is also industrially important, especially
when nutritional, technological and sensory specific standards are
desired. Industries have shown an increasing interest in type II
sourdoughs, but they require faster acidification without losing the
baking and sensorial properties (Messens and De Vuyst, 2002).
Currently, traditional and industrial processes have specific needs
such as constant rheology and flavour properties of the bread, so,
daily propagation of sourdoughs must be reduced to lower timeconsuming
processes and risks and sourdough must be adapted
for fast fermentation processes without losing the major properties
of lactic acid bacteria
