Abstract: The present invention relates to a method for monitoring the progression of the bisulfite-mediated conversion of DNA during DNA methylation analysis. The method is based on the reaction of the enzyme uracil-DNA-glycosylase (UNG) with at least one labeled DNA reporter molecule, the reporter molecule comprising at least one unmethylated cytosine residue in its sequence. After bisulfite-mediated conversion of unmethylated cytosine residues in uridin residues UNG removes the uracil bases from the DNA backbone, thus making it susceptible to heat-induced hydrolytic cleavage. Finally, the labels released from the DNA reporter molecule during this fragmentation process are detected.

Abstract: The invention discloses a method for production of polyhydroxybutyrate-co-polyhydroxyvalerate (PHBV) by recombinant Escherichia coli harboring plasmid containing both phaCAB and prpE. Different percentage of hydroxyvalerate can be obtained from the recombinant E. coli when cultivated in the medium containing different concentrations of propionic acid. In this patent, we provide a method that integrated all of the genes (i.e. phaCAB, vgb and prpE) required for PHBV production into a single plasmid. The plasmids were then transformed into an E. coli host. Results showed that PHBV can be produced by this recombinant E. coli, and the ration of HV to HB in the co-polymers can be regulated by addition of different concentrations of propionic acid in the medium. The percentage of HV in the co-polymers can be adjusted from about 3% up to more than 35%.
