    Many industrial processes may quickly proceed with biotechnological and enzymatic support. Functional and production facilitator properties of enzymes have provided variable advantages for industry. Therefore, enzyme utilization has become inevitable for industry and supplied financial advantages in case of the high energy requirement process. In the study, the amylase enzymes were isolated from thermal spring sources, and the effect on bread quality was examined. Firstly, fungal amylases were isolated from thermal spring sources (29–98 °C) in various places around Turkey. After determining the functional properties of amylase enzymes, the most active enzyme was used in bread production to examine their effect on bread quality. The maximum alpha-amylase activity (38.6 U/mg) has been detected in Aspergillus niger G 2–1 isolate. When compared with the commercially available one, native alpha-amylase increased the bread volume. A significant difference (p < 0.01) was found in the color properties and size of the bread between microbial produced in this study and commercially produced alpha-amylase. Five ppm alpha-amylase addition showed the optimum bread properties for dough processing.
