ResumenThe reparameterization of two classic growth models (the logistic and Gompertz equations), and the dynamic modification of the integrated form of the first of these, was applied to the description of the kinetics and metabolic behaviour of six strains of lactic acid bacteria in four media: three of these from visceral waste from fishing products, and one commercial medium. The descriptions obtained –always consistent models and statistically significant parameters– provided a wide range of reliable numerical values on notable characteristics of microbial growth and bioproductions, which allowed the assessment of the individual systems by direct comparison, and also the suggesting of the potentially most suitable groups (of species of fish and of bacteria) for bio-silage processes
