NºPublicación: US2019263871A1 29/08/2019

Solicitante:

DEXTER JASON [US]

WO_2018017828_A1

Resumen de: US2019263871A1

The invention comprises a photoautotrophic organism, generally having simpler nutritional requirements than heterotrophic organisms, utilized as a chassis for the heterologous expression and function of enzymes, or derivatives of said enzymes, that show activity toward the degradation/detoxification of toxins known to be associated with and specific to harmful algal blooms. As an example, a cyanobacterial strain (Synechocystis sp. PCC 6803) modified to express Sphingomonas sp. USTB-05 MlrA enzyme functionality, showing the capability of degrading microcystins (results shown here) and nodularins, is presented. Under modelled natural conditions, results indicate that heterologous enzymatic activity against microcystin-LR is more stable over time when utilizing a photoautotrophic chassis in comparison to use of a heterotrophic bacterial strain. In addition, both the viability and cell density of the photoautotrophic host is maintained for a significantly longer period of time, compared to a heterotrophic host.

WO_2017214077_A1

Resumen de: US2019225932A1

A Tris-Acetate-Phosphate-Pluronic (TAPP) medium that undergoes thermoreversible sol-gel transitions to efficiently culture and harvest microalgae without affecting productivity. After seeding microalgae in a TAPP medium in solution phase at 15 degrees C., the temperature is increased by 7 degrees C. to induce gelation. Within the gel, microalgae grow in large clusters rather than as isolated cells. Such clusters are easily harvested gravimetrically by decreasing the temperature to bring the medium to a solution phase. The settling velocity of the microalgal clusters is approximately ten times larger than that of individual cells cultured in typical solution media. Hence, microalgae can be cultured without constant mixing and about 90 percent of the biomass can be harvested in an energy efficient fashion.

Resumen de: AU2019204906A1

An IBTL system having a low GHG footprint for converting biomass to liquid fuels in which a biomass feed is converted to liquids by direct liquefaction and the liquids are upgraded to produce premium fuels. Biomass residues from the direct liquefaction, and optionally additional biomass is pyrolyzed to produce structured biochar, hydrogen for the liquefaction and upgrading, and CO2 for conversion to algae, including blue green algae (cyanobacteria) in a photobioreactor (PBR). Produced algae and diazotrophic microorganisms are used to produce a biofertilizer that also contains structured biochar. The structured biochar acts as a nucleation agent for the algae in the PBR, as a absorption agent to absorb inorganics from the biomass feed to direct liquefaction or from the liquids produced thereby, and as a water retention agent in the biofertilizer. The ratio of cyanobacteria to diazotrophic microorganisms in the biofertilizer can be selected to optimize the so as to achieve desired total chemically active carbon and nitrogen contents in the soil for a given crop.
