Sequencing of the 16S rDNA of the isolates followed by BLAST search revealed that nine strains could be identified as<i> Bacillus licheniformis</i> and one . A wide diversity of physiological abilities is exhibited, ranging from psychrophilic to thermophilic, and acidophilic to alkaliphilic; some strains are salt tolerant and some are halophilic. The mucoid phenotype is due to the presence of a thick polysaccharide capsule. When grown on common nutrients, it forms a round, milky, rough, yellowish, or translucent colony with jagged edges. This protease is an active ingredient in laundry detergents, removing protein-comprised dirt in clothes. The complete nucleotide sequence of B. licheniformis is ATCC 14580 genome which forms a circular chromosome of 4,222,336 base-pairs (bp) containing 4,208 predicted protein-coding genes with size averaging at 873 bp, 7 rRNA operons, and 72 tRNA genes. There are increased concerns regarding microbial contaminations, from such bacteria as E. coli and B. licheniformis, when it comes to food processing. They are often beta-hemolytic.

There is current research on B. licheniformis (strain SB3086) and its effects as a microbial fungicide. Bacillus subtilis bacteriocins can affect a much wider range of potentially pathogenic bacteria than the bacteriocins of other, more commonly-used bacteria such as Lactobacillus. Bacillus licheniformis, Bacillus subtilis and Bacillus pumilus are some of the strains that are associated with food spoilage and with a wide range of different clinical conditions (Turnbull, 1997). Feather degrading bacteria may have played an important role in the evolution of molting, and patterns in feather coloration (Gloger's Rule). Because it is capable of forming endospores that can be easily disseminated, B. licheniformis can be isolated from a variety of places, though it is mainly associated with plant materials. : #22892] Cell shape: rod-shaped [Ref.
