In order to understand the mechanism behind the high production of L-malate(LMA) by Aspergillus sp.N1-14',its total DNA was extracted to be used as the template,homologous primers were designed to amplify the segment containing the full length of the pyruvate carboxylase gene(pyc) and the malate dehydrogenase gene(mdh),and sequencing was then performed.Based on the results of this sequencing,the coding regions of pyc and mdh were identified,their coding sequences were amplified from the total c DNA of N1-14...
