Resumen de: MX2025003579A
The present invention proposes a new closed design and structure for the photobioreactor in the form of an octagonal prism ringed, strong and resistant to strategic conditions provided internally with a flat rectangular geometry culture container, a controlled lighting, agitation and heating system horizontally aligned to take advantage of the internal space of the structure, integrating sensors for monitoring and controlling the variables previously mentioned as well as sensors for monitoring and measuring PH, optical density and oxygen production of the microalgal culture. It is essentially characterised in that it is a closed system designed to operate in strategic conditions. This FBR is relatively inexpensive to build and of simple operation. The space exploration industry is strengthened by this invention since it can favor the future of manned trips through survival for longer periods of astronauts. However, before large-scale cultures of microalgae are possible in missions or spatial bases, small-scale functional FBR are necessary.

Resumen de: WO2026207238A1
The present disclosure provides a system for harvesting microalgae, comprising a cylindrical vessel configured to contain a suspension of microalgae, the cylindrical vessel having a longitudinal axis oriented predominantly perpendicular to gravity. A rotation mechanism is configured to rotate the cylindrical vessel around its longitudinal axis at a speed sufficient to induce either suspension or aggregation or both of the microalgae through fluid dynamics and sedimentation. Algae can be cultivated directly in the vessel. A harvesting mechanism is configured to remove aggregated microalgae from the cylindrical vessel. Different configurations for the harvesting mechanism are proposed and viable for different applications. The system enables efficient microalgae cultivation and harvesting without chemical flocculants by utilizing controlled fluid dynamics to promote natural aggregation, thereby reducing energy consumption and simplifying downstream processing.

Resumen de: US20260275393A1
The present invention relates to methods, compositions, and systems for modulating cellular metabolism in cyanobacteria, particularly F. diplosiphon, through the administration of nanoparticles including zero-valent iron nanoparticles (nZVIs) and titanium dioxide nanoparticles (n-TiO2), β-lactam antibiotics such as ampicillin, or combinations thereof. The disclosed methods enable controlled alteration of adenosine triphosphate (ATP) concentrations, ATP synthase expression, lactate metabolism, photosynthetic efficiency (Fv/Fm), reactive oxygen species (ROS) levels, thylakoid membrane morphology, and monounsaturated fatty acid (MUFA) production. A combination regimen of ampicillin and nZVIs partially rescues ATP levels otherwise depressed by nZVI treatment alone and enhances MUFA production. Administration of n-TiO2 at optimal concentrations enhances ATP synthase expression, photosynthetic efficiency, and growth in a strain-specific manner. Applications include sustainable biofuel synthesis and bioproduct manufacturing.

Resumen de: ES3078635A1
The invention consists of a method for determining the purity of microalgae cultures, allowing the determination of the purity of the microalga of interest, as well as the percentage of contamination by other microalgae that may commonly grow alongside it. This method uses only a spectrophotometer to obtain absorbance scans between 350 and 750 nm. These scans are then normalized and analyzed using a 1D convolutional neural network trained to recognize the species of interest. The result of the invention is a quantification of the culture purity of the species of interest, as well as the percentage of other contaminants present. This allows for the rapid characterization of cultures, is low-cost, and is easily applicable in any microalgae production facility, including those for cyanobacteria.

Resumen de: US20260265101A1
The present invention discloses a process mode of microalgal cultivation in semi-continuous on wine wastewater with no need to recirculate the microalgal biomass in the reactor, without dilution and sterilisation of the effluent applied as a growth medium. The process was experimentally carried out by semi-continuously applying, without recirculation of the biomass, the cultivation of Chlorella vulgaris on the digestate from the anaerobic co-digestion of winemaking lees and waste activated sludge. The integrated anaerobic digestion-microalgae treatment process is advantageous from a circular economy perspective as it leads to the exploitation of grape processing chain waste, eliminating the economic burden on producers and involving: i) the phyto-depuration of the effluent, ii) the production of bio-methane and iii) the production of biomass containing high value-added by-products (lipids, proteins and starch) that can be used to produce biodiesel, animal feed, nutraceuticals/pharmaceuticals and for producing bioplastics.
