title: Microcalorimetric studies on the polyhydroxyalkanoates production of recombinant Escherichia coli.
abstract: The thermogenic curves of metabolism of two strains of Escherichia coli pUC19cab/XL-IBlue and XL-IBlue have been determined by using a LKB-2277 bioActivity Monitor and ampoule method at 37 degrees C. pUC19cab/XL-IBlue was a recombinant E. coli strain bearing a foreign plasmid pUC19cab which brought the polyhydroxyalkanoates (PHAs) production. XL-IBlue was a host bacterium without any foreign DNA. Our studies reveal that the PHA production of recombinant E. coli has an apparent influence on their thermogenic curves of metabolism and therefore the initial time of PHAs production can be determined from these thermogenic curves.
