| Comparative studies on the growth of Micrococcus varians were carried out in BHI culture medium (control) as well as in a culture medium with 2% diluted sugar cane blackstrap molasses, enriched with 0.1% yeast extract. The experiment was conducted with three samples of the experimental and control media in a 5 liter fermentor with working volume of 3.5 liters, continuous agitation (150 rpm), 35 ± 0.1°C temperature, 0.7 L air. l-1 medium. min -1, initial pH 7.0 ± 0.2, 24 hour fermentation period, and approximate inoculum of 6.0 log10 CFU/ml. Samples were collected at 2-hour intervals. Micrococcus varians grew in the two culture media studied, which confirms the experimental medium viability for the growth of this species. The final average concentration of... |

| Comparative studies of Lactobacillus plantarum were carried out in MRS broth (control) and in 3% (w/v) sugar cane blackstrap molasses enriched as follows: 0.5% yeast extract, 0.5% ammonium citrate and 0.5% sodium acetate (Medium 1) and 0.5% yeast extract, 0.5% ammonium citrate, 0.5% sodium acetate, 0.5% ammonium phosphate, 0.2% ammonium citrate, 0.1% Tween 80 and 0.005% manganese sulphate (Medium 2). The experiment, was carried out at a 5 L fermentor, with 3.5 L as working volume. At the end of the fermentation period MRS presented the highest viable cells production (28.68 log CFU/mL) while in Medium 2 it was 25.80 and in Medium 1 19.36 log CFU/mL. Biomass productivity was 0.0865 g.L-1.h for MRS (control), 0.0768 and 0.0507 g.L-1.h for Medium 2 and Medium... |
