This rigidity helps to maintain the rod shape of the cell and can withstand high intracellular pressure. Bacillus subtilis morphology describes rod-shaped, Gram-positive bacteria that show up on both positive and negative Gram stain techniques. Umbonate elevation. This protease is an active ingredient in laundry detergents, removing protein-comprised dirt in clothes. 40. 7(4):204-211. There is also research about the possibility that B. licheniformis causes changes in color in birds' feathers; this will provide information on the evolution of molting. Circular form, entire margin. B. licheniformis is also an important ingredient in laundry detergent. [5][6] It was initially named Clostridium licheniforme by H. Weigmann[7] and renamed Bacillus licheniformis by Frederick D.

Biology. 37. Bacillus subtilis morphology describes rod-shaped, Gram-positive bacteria that show up on both positive and negative Gram stain techniques. Feathers contain high amounts of non-digestible proteins, but researchers hope that, through fermentation with B. licheniformis, they can use waste feathers to produce cheap and nutritious feather meal to feed livestock. Morphology of Bacillus subtilis. Phenol is a highly persistent environmental pollutant and is toxic to living organisms. Since this bacterium grows in alkaline conditions, it produces a desirable protease that can survive at high pH levels. The ability of B. licheniformis to form endospores allows it to survive in the harsh environments required to manufacture industrial enzymes, chemicals, and antibiotics. In the identification of bacteria and fungi much weight is placed on how the organism grows in or on media. FIG. : #22892] Cell shape: rod-shaped [Ref.

The strain was identified as Bacillus licheniformis GL174 and its endophytic attitude was validated by plating surface-sterilized inoculated cuttings. High capacity of secretion of the alkaline serine protease has made B. licheniformis one of the most important bacteria in industrial enzyme production. 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. licheniformis. microbial colonies that showed mucus morphology were streaked on TSA plates to obtain pure cultures. The death kinetics for B. licheniformis ATCC 14580 spores in cloudberry jam was examined under ohmic heat inactivation and conventional heat inactivation.

It can even go as far as causing abortions in pregnancies and impair sperm motility. Bacillus subtilis is a Gram-positive, rod-shaped bacterium that is the type species of the genus Bacillus, commonly used as a model organism to describe the structure of different species of the genus. Bacillus licheniformis is a ubiquitous bacterium commonly found in the soil and wasted organic material, and is used extensively for the production of industrial enzymes, such as amylase and protease (Waldeck et al. The cells often occur in pairs and chains, where the cells are joined together by polysaccharides on the cell walls. It was found in the fetal stomach contents showing it was able to enter the bloodstream of the adult and cross the placenta to a bovine fetus. As these bacteria extract carbon and produce heat, the plastic polymers slowly degrade. The bacterium was subcultured by cutting a chunk of the agar containing the organism and placing it in the middle of a TSA plate then incubating for 1 week at 37 C. 27. ; The cells of B. subtilis are Gram-positive motile rods that form ellipsoidal to cylindrical spores present centrally or paracentrally in the swollen sporangia.
