There is a wealth of available biological knowledge on and experimental methods for E. coli and B. subtilis. As a result, a number of extremely important E. coli and B. subtilis resources exist. Among these is the KEIO collection, a set of single gene knockout mutants of E. coli, and the BKE library of B. subtilis, the contents of which are recognized as international standards for genetic analyses of Gram-positive and Gram-negative bacteria. Bioresources for both E. coli and B. subtilis are important for advancing science and technology in both medical and industrial fields.
