"Complete genome sequence of the industrial bacterium Bacillus licheniformis and comparisons with closely related Bacillus species." [6][9] B. licheniformis is found in a wide variety of environments, but especially in soil and in the feathers of birds, where B. licheniformis degrades -keratin. Food borne outbreaks usually involve cases of cooked meats and vegetables, raw milk, and industrially produced baby food contaminated with B. licheniformis. 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. Also, cultures of B. licheniformis are made to retain its protease, which is in turn used in laundry detergent. Outbreaks are predominately associated with cooked meats, vegetables, milk products, and baby food. W.B. The ability to turn waste feathers into feed would reduce feed costs and decrease the need for pollutants currently used to degrade these feathers [3]. Endospores allow the organism to survive in a variety of harsh environments (high salt concentrations, for example) until conditions are more favorable, when it returns to a vegetative state.
