Microalgae are grown in a biofilm on carriers. The carriers may have surfaces with a small angle to the vertical, optionally forming a cone. A surface of the carrier may be flexible and optionally include a porous material. Algae are harvested from the carriers using a water jet, which may provide a substantially solid stream of water. A nozzle for producing the water jet may spin while being moved laterally over a carrier bed. The water jet may dislodge algae from a surface of the carriers in the form of large agglomerates or blobs. The dislodged algae may have a high concentration of solids or readily settle. The algae may be collected from a floor below the carriers, optionally with a moving collection device. A moving harvesting device may treat a portion of a carrier bed such that harvesting of the entire bed is distributed over time.

Resumen de: WO2025255275A2
By engineering genetic traits associated with photosynthesis in plants, transgenic plants with increased crop yield can be generated, which will ultimately lead to increased food production in the field. To obtain beneficial genetic traits for enhanced photosynthesis, accelerated evolution is applied under salt stress in a cyanobacteria species, Synechococcus elongatus PCC 7942, by conditionally suppressing its mismatch repair system. Through high-throughput screening for biomass accumulation and sucrose production, it is discovered that specific amino acid changes in the pre-Dl protein of Photosystem II (PSII), encoded by the psbA genes, can improve efficiency of photosynthesis under salt stress, as well as pathogen resistance. Next, the same amino acid changes were made in Arabadopsis and proved that photosynthetic efficiency (measured via growth rate) is also increased in this model vascular plant.

Resumen de: US2025368946A1
An algal biofilm harvesting method capable of reducing release of planktonic microalgae includes the following steps: S1: constructing an algal biofilm treatment system; S2: calculating a cutting area; S3: harvesting microalgae biomass; and S4: cyclic harvesting. By constructing an algal biofilm treatment system, a surface of an algal biofilm can be regularly cut to harvest microalgae biomass, thereby keeping activity of the biofilm in a best state all the time. In addition, the harvested microalgae biomass can be used as a high-quality substrate for subsequent fermentation, which can achieve resource saving. Quality attainment of effluent from a sewage tank with planktonic microalgae as a suspended solid indicator can be achieved, the treated effluent can be prevented from deteriorating due to an increase of the planktonic microalgae, and a risk that the planktonic microalgae in the effluent of the algal biofilm affects a subsequent treatment process is reduced.
