  abstract = {{T}he aim of this work was to study the capability of amylolytic lactic acid bacteria to hydrolyse the glycogen in mussel processing wastes ({MPW}) for lactic acid production. {F}rom four strains tested, #{L}actobacillus plantarum$ {A}6 was selected. {C}ultures of this strain on {MRS} medium with starch or mussel glycogen, showed similar levels of amylase production for both polysaccharides. {W}ith glycogen, sugar comsumption rate was lower than with soluble starch and, although the micro-organism produced higher yields of enzyme, a fraction of approximately 20% of the total sugars remained undergraded. {H}owever, the different substrates did not seem to induce the production of different types of amylase and the values of the apparent {K}m for starch and for glycogen were close, revealing a similar affinity for both substrates. {T}herefore, the differences in hydrolysis and consumption of the substrate seem to be related with the higher grade of branching of glycogen. {C}ulture in {MPW} showed a decrease in p{H} unfavourable for amylolytic activity and uncoupling between lactic acid and biomass production. {B}y controlling p{H} and increasing the initial protein concentration to avoid uncoupling, similar lactic acid production and higher yields than obtained with starch were reached with {MPW}.
