Table 1. Summary of the alkaline protease from A. pallidus C10 purification procedure.
Figure 1. Neighbor-joining phylogenetic tree on the basis of 16S rRNA gene sequence data of the thermophilic bacteria. Alicyclobacillus acidiphilus DSM 14558 was used as out-group. Bootstrap values based on 1000 replications are listed as percentages at branching points. Only bootstrap values >50% are shown at nodes. The scale bar represented 1% divergence.
