In high dentity fermentation, the cellular respiration, energy metabolism, highest bacterial density and dry bacteria weight of the G830 strain were markedly better than control strains PA1 and BL21, The expression of recombinant prolyl endopeptidase in G830 and PA1 under the above condition was high and stable. Their growth situation and fermentation parameters were similar with their parental strains without plasmids, and resided plasmids maintained stably in those strains.
