The identification by classical method showed that they belonged to the genus <em>Bacillus</em>.</p> <p>The nucleotide sequence of the 16S-RNA<strong> </strong>gene of these two strains showed that the one of the strain <em>Bacillus</em> IBT012 had 98% homology with the one of the strain<em> Bacillus subtilis </em>2633 and<em> </em>the one of the strain<em> Bacillus </em>HA401 had<em> </em>97% homology with the one of the strain <em>Bacillus subtilis </em>2633<em>. </em>Therefore, these two isolated strains belonged to the species <em>Bacillus subtilis. </em></p> The nucleotide sequence of the16S-RNA gene of the strain<em> Bacillus </em>HA401<em> </em>was submited to the NCBI genbank database with the genbank accession number: AY279207.
