Abstract
|
|
|
|
Repeated-batch and continuous cultures of Lactococcus sp. 1112-1 were carried out for bacteriocin production using a glucose-casein medium. Repeated-batch culture did not efficiently enhanced the bacterlocin production. Continuous production was possible at the dilution rate of 0.4 h^-1. Maximum specific production rate (Q_p), bacteriocin production and biomass at the dilution rate were 347,136 IU/g/h, 2,121 IU/㎖ and 2.45 g/L, respectively.
