Effect of Salt Concentration on the Production of α-Amylase and Protease by Bacillus coagulans and Wastewater Treatment Potential

Tran Quang Vinh, Nguyen Hoang Dung, Do Dang Giap, Phan Van Dan & Tran Trung Kien · Biotechnology Journal International · 2025

Bacillus coagulans is a moderately halotolerant bacterium with potential applications in enzyme production and wastewater treatment in brackish aquaculture systems. In this study, we examined how different NaCl concentrations (0 - 5%) affect the growth and extracellular α-amylase...
