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.

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.

The system comprises a primary tank, a screening unit with a motor-driven cleaning mechanism, a flocculation tank supplied with a chemical flocculant, a sand filter, an acidification unit with pH control, a solid-liquid separation unit, an anaerobic digestion unit, and a microalga cultivation unit. The effluent is screened, flocculated, filtered, acidified to a pH from 4.2 to 5.2, preferably 4.45 to 4.75, and subjected to solid-liquid separation to remove precipitated proteins and destabilised colloidal material, thereby producing a clarified effluent. The clarified effluent is anaerobically digested at a defined organic loading rate to generate biogas and a liquid digestate. At least a portion of the digestate and/or carbon dioxide derived from the biogas is used for microalga cultivation. The system enables stable anaerobic digestion without membrane-based pretreatment and provides a conditioned stream suitable for downstream microalga growth.

The present invention relates to a symbiotic therapeutic technique based on a genetically modified eukaryotic microalga (51), preferably photosynthetic, such as for example Chlamydomonas reinhardtii, in which an expression cassette (10) codifying a biologically active peptide and/or protein comprises a secretion coding module (5) of a therapeutic agent to allow the biologically active peptide/protein to be released so that it can cross the cell wall of the microalga (51), to be secreted outside of it and enter directly into the circulation in a subject (53) in which said genetically modified eukaryotic microalga (51) has been subcutaneously or intradermally injected. The microalga can be of a type that naturally: a) lacks flagella; or b) has flagella, in which case a prior genetic modification prevents the formation or inactivates the flagella, so that the microalga remains immobilised at a subject injection site (53). The expression cassette (10) can further comprise at least one further coding module selected from: a homing module (6), for targeting the peptide/protein to a predetermined tissue and/or cell population of the subject (53); a penetrating module (7) for inducing internalisation of the protein within a cell of said subject (53) through the cell membrane or by induced endocytosis; a protection module (9). The invention also relates to a subcutaneously or intradermally injectable composition containing said microalgae, and to a kit for preparing said composition.
