Bacillus thuringiensis You must discuss your chosen organism to tell us what type of microbe it is, what helpful beneficial actions it performs and which subfield of microbiology it is involved in. You must discuss only the helpful, beneficial, positive aspects of your chosen organism for your entire main discussion

Write about the microbe Bacillus megaterium and its morphological, phylogenetic, and genomic characteristics. division of labor, description of it and its role, and how it communicates in the community (thru quorum sensing? metabolites) what are its abiotic characteristics and how does it impact community function and if it is responsible for c input and n input/ output? what genes are necessary, how do they perform ?

The motile alga Micromonas: What is the minimum number of organelles this alga must have? Two types of prokaryotic cells have been distinguished: bacteria and archaea. How do these cells differ from each other? How are they similar? A 0.5-mm cell was discovered in surgeonfish and named Epulopiscium fishelsoni. It was presumed to be a protozoan. In 1993, researchers determined that Epulopiscium was actually a gram-positive bacterium. Why do you suppose this organism was initially identified as a protozoan? What evidence would change the classification to bacterium? When E. coli cells are exposed to a hypertonic solution, the bacteria produce a transporter protein that can move K+ (potassium ions) into the cell. Of what value is the active transport of K+, which requires ATP? Clinical Applications: Clostridium botulinum is a strict anaerobe; that is, it is killed by the molecular oxygen (O2) present in air. Humans can die of botulism from eating foods in which C. botulinum is growing: How does this bacterium survive on plants picked for human consumption? Why are home-canned foods most often the source of botulism? A South San Francisco child enjoyed bath time at his home because of the colorful orange and red water: The water did not have this rusty color at its source, and the water department could not culture the Thiobacillus bacteria responsible for the rusty color from the source. How were the bacteria getting into the household water? What bacterial structures make this possible? Live cultures of Bacillus thuringiensis (Dipel) and B. subtilis (Kodiak) are sold as pesticides. What bacterial structures make it possible to package and sell these bacteria? For what purpose is each product used?
