Spores of bacteria of Bacillus species are extraordinarily resistant to all manner of harsh treatments, and largely because of this resistance, spores of some Bacillus species are major agents of food spoilage and food-borne and other diseases (eg-Bacillus anthracis).

I work with Bacillus subtilis 168 wild type species, and some other bacillus species. Growth conditions are simple, first try to grow on 0.5 LB agar plate ( 1% tryptone, 0.5% Yeast extract, 0.5%.

With this operating premise, Onuchic and Levine, along with a small cadre of colleagues, plan to use the framework to engineer new, predictable behaviors in a model bacterium called Bacillus subtilis.

The bacterium, despite its simplicity, contains a well-developed cell structure which is responsible for some of its unique biological structures and pathogenicity. Many structural features are unique to bacteria and are not found among archaea or eukaryotes.Because of the simplicity of bacteria relative to larger organisms and the ease with which they can be manipulated experimentally, the.
