The response to stepped pH profiles obtained by successive alkalisation was examined in cultures of seven species of lactic acid bacteria.
For at least four species, these conditions, combined with glucose fed-batch, promoted greater efficiency of nutrient consumption, stimulated
biomass and bacteriocin production, and prolonged the productive period of the culture. In addition, they determined the appearance of
heterofermentative phases absent in conventional culture, with pH either in spontaneous evolution or controlled to a stable level. The advantages
and difficulties of various approaches here developed for the mathematical modeling of this system are discussed in useful terms to incorporate
with control purposes to the software of a biorreactor, and the implication of the pH gradient is suggested in results from other authors, relative
to the metabolic typology and production conditions of bacteriocins.
