Process
The most frequent methods used are batch, fed-batch, repeated batch, and
continuous for lactic acid production. Fed-batch cultures produce higher
quantity of lactic acid than in continuous cultures. Continuous cultures
on the other hand produce higher productivity of lactic acid as well as
the possibility to continue the process for a longer period of time. The
different approaches in producing lactic acid can be found in the table
below.
