Genomic and enzymatic insights into α-amylase-producing Bacillus spizizenii strains isolated from Isfahan province, Iran

The combination of robust enzymatic activity, exceptional environmental tolerance, and confirmed genetic basis positions these B. spizizenii strains as highly promising candidates for industrial enzyme applications. This work not only expands the known diversity of high-performance α-amylase producers but also provides valuable insights into the biotechnological potential of underutilized Bacillus species from unique geographical sources.
