  • Patent number: 9742152
    Abstract: A tunable distributed feedback (DFB) semiconductor laser based on a series mode or a series and parallel hybrid mode. A grating structure of the laser is a sampling Bragg grating based on the reconstruction-equivalent chirp technology. DFB lasers with different operating wavelengths based on the reconstruction-equivalent chirp technology are integrated together by a sampling series combination mode or a series/parallel hybrid mode, one of the lasers is selected to operate via a current, and the operating wavelength of the laser can be controlled by adjusting the current or the temperature, so that the continuous tuning of the operating wavelengths of the lasers can be realized. Various wavelength signals in parallel channels are coupled and then output from the same waveguide. An electrical isolation area (1-11) is adopted between lasers connected in series or lasers connected in series and connected in parallel to reduce the crosstalk between adjacent lasers.

  • Patent number: 8569469
    Abstract: Sequences of B12-dependent dehydratases with improved reaction kinetics are presented. Use of these B12-dependent dehydratases reduce the rate of the enzyme's suicide inactivation in the presence of glycerol and 1,3-propanediol. The enzymes were created using error-prone PCR and oligonucleotide-directed mutagenesis to target the DhaB1 gene, which encodes the ?-subunit of glycerol dehydratase. Mutants with improved reaction kinetics were rapidly identified using high throughput assays.

  • Patent number: 7879582
    Abstract: A method for the recombination of a gene is disclosed. The method involves the design of unpaired forward and reverse primers having homology to the 5? end of one template and to the 3? end of another template. Short primer extension periods results in a recombined template having paired 5? and 3? ends that can then be amplified. The amplified sample is devoid of any parental template.

  • Patent number: 7303900
    Abstract: Genes encoding phenylalanine ammonia-lyase (PAL), tyrosine ammonia lyase (TAL) and phenylalanine hydroxylase (PAH) have been introduced into a host organism for the production of Para-hydroxycinnamic acid (PHCA). The introduction of these genes results in the redirection of carbon flow in the host, optimizing the flow of carbon from glucose to PHCA. The intermediates, tyrosine and cinnamic acid are also produced.
