(2) Pereira R., Martins J., Mateus C., Teixeira J. Streptomyces albus cultivated on nutrient agar. The sample was grown at 4C for one month. Since it can grow in alkaline conditions, it produces a protease that can survive at high pH levels. The rod shape also helps bacteria glide or move through watery environments and provides regular building block shapes that make biofilm formation easier. Since about 80% of the coding sequence of B. licheniformis contain B. subtilis orthologs, it is considered part of the subtilis group.
