In recent years, the increasing interest toward bakery products
made with flours different from wheat has leaded to a
diversification in the market and to the necessity of developing
more appropriate starter cultures for specific products. With the
words “starter culture” one refers to a microbial preparation of
cells that is added to a raw material to produce a fermented food
by accelerating and driving its fermentation process (Leroy and
De Vuyst, 2004).
