0001 The present invention relates to an invention utilizing a microalgae extract as a medium additive for culturing cultured meat. More specifically, the present invention uses an extract of chlorella, which is a kind of microalgae, as a medium additive component, thereby making it possible to effectively induce cross-differentiation from muscle stem cells into adipocytes and provide cultured meat having improved flavor by inducing cells in which muscle fat is present at the same time. In addition, the use of the medium additive of the present invention replaces fetal bovine serum, which is a culture medium component for cultured meat, or is used in combination with fetal bovine serum, thereby enabling a reduction in the use of expensive fetal bovine serum and enhancing the culture effect of cultured meat, thus providing cultured meat having excellent cost effectiveness.

Provided are gene therapy vectors designated MEV-GTVs, which are MEVs that contain an ITR-containing plasmid (also referred to as a minigene plasmid) that comprises Inverted Terminal Repeats (ITRs), such as viral ITRs, and nucleic acid encoding a product of interest, and optionally regulatory sequences. The ITRs serve to circularize the minigene plasmid. The plasmids do not contain additional viral components, so that resulting DNA is not encapsulated in a viral capsid or envelop and is not replicated by viral genes. The plasmids can be inserted into bacterial plasmids for propagation.

Methods for processing microalgae, such as seaweed, in particular brown and green seaweed, are described, to extract polysaccharides with a reduced heavy metal content, reduced iodine content, and increased calcium content. We describe a process including the steps of: providing an algal biomass; extracting the algal biomass with at least one solvent; separating the solvent from algal biomass solids to provide an algal liquid and extracted algal biomass solids; adding a source of calcium ions to the algal liquid; clarifying the algal liquid to remove particulate and/or precipitated alginate from the algal liquid, to provide a clarified algal liquid; providing a protease enzyme to the clarified algal liquid; filtering the protease-treated clarified algal liquid to provide a retentate liquid comprising a bioactive polysaccharide extract and a permeate liquid; and filtering the permeate liquid to provide a liquid comprising a bioactive polysaccharide extract enriched in beta-glucan.
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.

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.

Resumen de: WO2026181093A1
Components of oily sludge contaminate the environment, disrupt the endocrine system, and are carcinogenic. Proper and complete treatment of the oily sludge followed by its safe disposal is essential to minimize environmental impact and protect human health. Existing treatment methods for oily sludge include incineration, landfilling, pyrolysis, and supercritical water oxidation; however, these techniques are energy-intensive, costly, and pose higher risks of environmental pollution. The present invention discloses a novel process for oily sludge degradation using a mild hydrothermal-assisted microalgae-based phycoremediation strategy. The method achieves 70– 75% degradation of long-chain aromatic and aliphatic hydrocarbons within 4–6 weeks. The degradation efficiency may further increase when the treatment period exceeds 6 weeks. Compared with conventional energy-intensive technologies for oil sludge treatment, the proposed method is more economical, environmentally sustainable, and suitable for long-term scale-up, with added potential for revenue generation.

Resumen de: WO2026177699A2
The invention relates to a method for producing a micro gas bubble immobilised microalgae culture for the removal of nitrogen and phosphorus in water and wastewater treatment. Said microalgae use nitrogen and phosphorus as nutrients while simultaneously forming biomass that can be used as a raw material for energy and other products. The method that is the subject of the invention enables the microalgal biomass to remain stable at the water surface by being immobilised with micro gas bubbles. In this way, the microalgae are able to receive the light required for photosynthesis and can be easily removed after the treatment process. This innovative approach aims to increase the efficiency of treatment processes while reducing energy consumption and operating costs.
