Recombinant DNA, microorganisms containing same and their use in the production of amylases. |
摘要 |
<p>Recombinant DNA has been developed which is derived from the plasmid pUB110. This plasmid comprises a gene coding for resistance to kanamycin or to analogous antibiotics inactivated by the nucleotidyl transferase enzyme.</p><p>The recombinant DNA containing an amylase-coding gene is prepared by the in vitro process of cleaving DNA derived from a donor microorganism and combining the resulting DNA fragments comprising the amylase-coding gene with a similarly cleaved vector which is plasmid pUB110. This recombinant DNA may then be introduced into a host microorganism and the resulting genetically engineered microorganism has been found to have enhanced stability and high copy numbers.</p><p>The host microorganism employed is preferably Bacillus subtilis and the invention is particularly suitable for the industrial scale production of the alpha-amylase of Bacillus megaterium.</p> |
