  abstract = {{T}he aim of this work was to study the possibility of monitoring citric acid production from mussel processing wastes ({MPW}) by #{A}spergillus niger$ in solid-state culture ({SSC}) on an inert support. {T}his was conducted by measuring {CO}2 and {O}2 concentration in exhaust gases, using an automatic sampler connected to a gas chromatograph and a data acquisition system. {T}he procedure permitted information on the physiological state of the culture to be obtained. {A} relationship between citric acid accumulation and a decrease in {CO}2 production was found, allowing citric acid production to be followed in real-time. {M}oreover, respiratory activity can be estimated and the effect of different variables on this parameter studied. {I}nitial nitrogen concentration, a critical factor for achieving high production of citric acid from {MPW} in submerged culture, revealed no effect in {SSC}. {T}his indicates a tolerance of {SSC} to higher concentrations of nitrogen constituting an advantage when using residual media with high levels of protein and variability in their composition.
