Fig. 1.
Growth curves of Bacillus subtilis and Lactobacillus rhamnosus. The incubation time was used as the abscissa, and the absorbance was used as ordinate to plot on the plot. The mid-logarithmic growth phase of these two strains was determined.
Fig. 2.
Fusion of the protoplast of the two strains; a, Protoplast of Bacillus subtilis; b, Protoplast of Lactobacillus rhamnosus; c, Fusion of the protoplast.
Fig. 3.
Acid production stability of the 5 regenerated bacterial strains.
Fig. 4.
Genetic stability of the 3 regenerated bacterial strains.
Fig. 5.
An image of growth on solid medium of three bacterial strains and a microscopy image of three bacterial strains (10×100): a and d were Bacillus subtilis, b and e were Lactobacillus rhamnosus and c and f were fusion of RH-3.
