Habitat Information
This soil organism was collected at the residence of 6804 Shier Cove in Austin, Texas. The soil was very dense and rough, about 1"-2" inches in depth. It resides in soils and some colonize in the root area of some plants where B.Pumilus has antibacterial and anti-fungal activity. Some purposes of B.Pumilus that are being researched are its involvement in bacterial hay preservation, and the use of B. pumilus plasmids in gene transfer systems. The proteases from B.pumilus are used in various industries. Food,chemical,detergent, and leather industries can benefit from the proteases from B.pumilus. The useof the plasmids from B.pumilus and insertion of other plasmids to the bacteria aide in various industries, and as anti-microbials and anti-fungals.
Description and Significance
Bacillus pumillus is a spore-forming bacteria that is rod-shaped, Gram positive, and aerobic.
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Include S Ribosomal sequence that you obtained from PCR and sequencing here.
Cell Structure, Metabolism and Life Cycle
B.pumilus is a Gram Positive, Rod shaped Bacteria, the outer layer of Peptidoglicon is covered by acids containing Polyglycosyl phosphates and dissacharides that help adhesion to host cells. These phosphate groups also can provide a negative charge on cell surface allowing capture of essential cations necessary for cell survival. There are three stages in the B.pumilus life cycle, Sporangium, vegetative cell, or free spore. Sporangia is where a spore is hanging out waiting for the right condition. In the vegetative the cell will undergo germination from a free spore when the conditions are right such as temperature and timing.
Physiology and Pathogenesis
It is rare for B.pumilus to make humans sick, but occasionally can cause damage to epithelial cells and cause food poisoning which then causes stomache cramps, back pain, diarrhea. B pumilus has also been known to cause lesions.
