  • Publication number: 20210285940
    Abstract: The inventive technology may include a tripartite fluorescent resonance energy transfer (FRET) based fusion protein complex having a ligand binding domain capable of binding to a target ligand and coupled with a donor-acceptor pair of chromophores moieties. The ligand binding domain may be positioned between the donor and acceptor chromophore moieties and may further bind to another ligand binding domain forming a homodimer complex. Ligand binding may cause dissociation of the homodimer complex leading to enhanced donor fluorescence emission and simultaneous quenching of the acceptor fluorescence emission, yielding significant decreases in the acceptor-to-donor fluorescence emission ratio. The tripartite FRET based fusion protein may be used as a biosensor, preferably for molecules responsible for bacterial quorum sensing.

  • Publication number: 20130224822
    Abstract: Genetically engineered algae strains for biofuels and bioproduct production have improved iron utilization including iron uptake and storage, and exhibit improved growth characteristics, magnetic separation, and magnetic hysteresis induced cell lysis. Pond production algal strain embodiments with high iron scavenging capabilities limit iron availability to contaminating microorganisms and invading species. Accumulation of high iron and other paramagnetic elements content in the form of ferritin enhances the cells magnetic susceptibility improving efficiency of magnetic separation and magnetic hysteresis induced cell lysis. Several genes of the embodiments are capable of improving iron acquisition including the ferritin gene fer1, iron transport gene fea1, and iron reductase gene fre1.
