A Microbial Biorealm page on the genus Bacillus licheniformis. Bacillus licheniformis is a bacterium that is commonly found in soil and bird feathers. Birds that tend to stay on the ground more than the bacollus i.

These bacteria are commonly known to cause food poisoning and food spoilage. Food borne outbreaks usually involve cases of cooked meats and vegetables, raw milk, and industrially produced baby food contaminated with B. This bacterium, although detrimental, can be modified to become useful.

Researchers are trying to turn bird feathers into a nutritious livestock feed by fermenting non-digestable proteins on bird feathers with Baci,lus. There is also research liheniformis the possibility that B.

Also, cultures of B. The complete nucleotide sequence of Bacillus licheniformis consists of the ATCC genome, which has a circular chromosome of 4, bp base pairs which contains 4, predicted protein-coding genes average size of bp7 rRNA operons, and 72 tRNA genes.

The GC content is The chromosome of B. But, although similar to B. Bacillus licheniformis is a rod-shaped, Gram-positive bacterium. It produces a variety of extracellular enzymes that are associated with the cycling of nutrients in nature. This bacterium can survive harsh environments by turning into spore-form; when conditions are good, it will turn back into a vegetative state. This protease is a desired ingredient in laundry detergent due to its ability to be used in low temperatures, which prevents shrinkage and fading colors.

Bacillus licheniformis forms spores in soil. A pathway that leads to endospore formation is initiated when the bacterium is starved. Endospore formation is actually desired and serves as a great example of prokaryotic development and differentiation. These spores are quite tolerant of heat, cold, radiation, and other environmental stresses. Under good conditions, the spores will germinate and produce vegetative cells. It is an apathogenic soil organism that is mostly associated with plant and plant materials in nature.

Although it is most common to isolate this bacterium from is soil, it is believed that B. Ecologists are studying the effects of B. It is believed that this bacterium is involved in the evolution of molting and patterns of color in birds due to its feather degrading capability.


Bacillus licheniformis is commonly associated with food spoilage and poisoning. It causes bread spoilage, or more specifically, a condition called “ropy bread” 1.

Contamination with this bacterium will make the bread sticky and stringy; the ropy bread will also start to develop a strong odor after contamination.

Rope spores is what causes the spoilage; unfortunately these spores do not get killed during the baking process. Septicaemia is blood poisoning, and is classified as having a large amount of bacteria in the blood. Dairy products are at increased risk of being contaminated with toxin-producing isolates of B.

Cooked meats, raw milk, vegetables, and processed baby foods are also at risk. The symptoms include stomach pains, acute diarrhea, and possible vomiting.

These have an onset time of hours and last no longer than 36 hours. It can cause ophthalmitis, which is the inflammation of the eye. It can even go as far as causing abortions in pregnancies and impair sperm motility. The toxins produced by B. Researchers are trying to recycle bird feathers by turning them into nutritious food for livestock. As mentioned, Bacillus licheniformis is commonly found on bird feathers; by fermentation with B.

Bacillus licheniformis

This is desired because it licheniformix cheap and nutritious. Ecologists are looking for signs of association between the plumage feathers and B. Since it can grow in alkaline conditions, it produces a protease that can survive at high pH levels. The protease has an optimum pH at around 9 and 10, which is desirable since it can remove protein-comprised dirt in clothes. Researchers culture and isolate this protease to add it into detergents. This protease prevents shrinkage and fading colors since it allows lower temperatures to be used, which in turn lowers energy use as well.

Bacitracin is composed of a mixture of the cyclic polypeptides that B. Bacitracin lyses the proplasts of B. Bacillus licheniformis is a spore-forming soil organism that contributes to nutrient cycling and has antifungal activity.

There is current research on B. Novozymes Biofungicide Green Releaf contains B. This fungicide can be licheniformiw on lawns, conifers, tree seedlings, ornamental turf and ornamental plants in outdoor, greenhouse, and nursery sites. There are concerns regarding licheniforims safety of this fungicide.


Bacillus licheniformis – Wikispecies

Reports about Bacillus licheniformis having detrimental effects on insect, avian, plant, and estuarine marine species are fortunately almost licheniforis. There have been reports of reproductive failure and mastitis caused by this baccillus in cattle, sheep and swine.

It fortunately does not have any detrimental effects on endangered species. There is an increased interest in using a protease isolated from Bacillus licheniformis in laundry detergents. Since this bacterium grows in alkaline conditions, it produces a desirable protease that can survive at high pH levels. This protease is an active ingredient in laundry detergents, removing protein-comprised dirt in clothes. The desirable properties of this protease are its prevention of clothes shrinkage and fading colors due to its capability to be used at lower temperatures.

This system uses DNA-based diagnostic tool to monitor fermentation processes such as the production of enzymes for Henkel laundry detergents. Currently there are many electrical techniques for food processing, one licneniformis example is Ohmic heating. Ohmic heating has potential uses such as blanching, evaporation and pasteurization of food; it is a high temperature, short time, and a purely bulk heating method.

There are increased concerns regarding microbial contaminations, from such bacteria as E. Current research try to find the “death kinetics” 2 of these bacteria. Death kinetics, in this case, involves the intensity of heat treatments and their correlation with the rate of death of a bacterium.

The death kinetics for B. Results of studies show that the ohmic heating has a quicker death kinetic rate, meaning shorter and less aggressive treatments can be used to kill off B.
