Abstract :

This study was aim to determine the growth pattern of Bacillus megaterium probiotic bacteria on varying the concentration of molasses, the combination effect of molasses concentration and incubation time on total of Bacillus megaterium probiotic bacteria and viability of Bacillus megaterium probiotic bacteria at the end of incubation on varying molasses concentration. Varying the concentration of molasses were made from molasses concentration of 0% (NB), molasses concentration of 1%, molasses concentration of 2% and 3% molasses concentration with an incubation period of 12 weeks. Data of patterns growth and viability of Bacillus megaterium probiotic bacteria on the final incubation in molasses concentration variation were obtained from the average total of Bacillus megaterium bacteria every week. Data of concentration molasses and incubation time combination on total of Bacillus megaterium probiotic bacteria were analyzed statistically by Brown Forsythe test. Differences between treatments were tested using the Games Howell. The results of total bacteria showed differences growth patterns Bacillus megaterium bacteria on molasses concentration variation. Statistical analysis showed that combination effect of molasses concentration and incubation time influenced the total probiotic bacteria of Bacillus megaterium. Viability of Bacillus megaterium probiotic bacteria at the end of the incubation period on varying the concentration of molasses is still good.
