<abstract language="eng">Comparative growth studies of Pediococcus pentosaceus were done in MRS (control) culture medium as well as in culture medium of 5% sugar cane blackstrap molasses (Broth 1) enriched with yeast extract (Broth 2) and enriched with beef extract (Broth 30. The experiment was carried out in a shaker (96 rpm) in 250 mL Erlenmeyers flasks with working volume of 150 mL, initial inoculum of about 10³ - 10(4) FCU/mL, at 35 ± 1ºC temperature and 28-hour fermentation. The biomass pruductivity was higher in MRS broth (0.0375 g/L.h), followed by Broth 2 (0.0275), Broth 3 (0.0189) and Broth 1 (0.0151). The higher viable cells number occured in MRS (13.96 log10 FCU/mL), followed by Broth 2 (12.09), Broth 3 (10.12) and Broth 1 (8.42).
