Abstract
The gene coding for a thermostable pullulanase enzyme is incorporated into chimeric plasmids which are inserted into and reproduced by E. coli or B. subtilis host microorganisms. When microorganisms containing the chimeric plasmids are grown in fermentation media, they produce the pullulanase enzyme.
