FIG. 2.

Lipase (FDPr) and dehydrogenase (RSZ) enzymatic activities of T. vulgaris measured every 30 min. The enzymatic activity of dormant spores is seen at t = 0; that of activated spores is seen at t = 0.5 h. The measurements between 1 and 5 h show the enzymatic activity during the spore development from activated spore status toward the vegetative cell status. Error bars indicate the standard deviations from the means of four repeats. Statistical analysis with analysis of variance and Scheffe’s test indicated that a < b (P < 0.05).
