“…These difficulties could be solved by selecting adequate operating conditions and scale-up criteria, which should be based on the microorganism metabolism, monitoring parameters in PCB such as O 2 consumption and CO 2 production. Both have been used to estimate the growth of the microorganism 11,12 and the heat generation 9,10 of the culture. Therefore, in this work, a respirometric analysis was carried out in cultures of M. robertsii; and kinetic parameters associated with O 2 consumption and CO 2 production were mathematically estimated.…”
