Abstract
The ability of selected lactic acid bacteria to inhibit the growth of
rope-forming Bacillus strains in laboratory experiments and in wheat bread
was investigated. Growth of Bacillus subtilis and Bacillus licheniformis was
inhibited by Lactobacillus plantarum VTT E-78076 and Pediococcus pentosaceus
VTT E-90390 in an automated turbidometry assay and in test bakings. Rope
spoilage of wheat bread was inhibited by adding 20-30 g of sourdough/100 g
of wheat dough if the sourdough was fermented with Lactobacillus plantarum
VTT E-78076, Pediococcus pentosaceus VTT E-90390 or Lactobacillus brevis
(commercial starter culture) and the pH values of sourdoughs were adjusted
below 4.0 and the amount of total titratable acidity value was >12. Addition
of lactic acid alone in concentrations comparable with those formed in
sourdoughs did not prevent rope spoilage. Copyright 2002 Elsevier Science
