The invention relates to the production of microalgae biomass. The microalgae contained in a suspension of water and microalgae are continuously phototrophically or mixotrophically cultivated in a cultivation module (1), which is passed multiple times by the suspension and has a gas part and a liquid part with a liquid supply (3), by supplying light from at least one artificial light source (5) and nutrients. According to the turbidity established by sensors, volume fractions of the suspension are repeatedly discharged from the cultivation module (1) for the harvest of microalgae and removed by means of a centrifuge (7). The cultivation of the microalgae occurs in an climate chamber forming the cultivation module (1), which is operated using water. Alongside a regulating of the temperature of the suspension, there also occurs a regulating of its pH value via the controlled addition of buffer ions and a regulating of the redox potential of the suspension and thereby also of its microbial contamination by controlling the light and nutrient supply, as well of a metered addition of oxygen. In addition, after the removal of microalgae, the remaining suspension is irradiated with UV light in order to kill unwanted microbial contamination before being returned into the cultivation module (1).

Resumen de: WO2022053689A2

The invention relates to a novel method to produce small RNAs targeting virulence factors, essential genes and /or antimicrobial resistance genes of phytopathogens. More specifically, the invention involves the expression of exogenous RNA interference (RNAi) precursor(s) in Chlorella cells, which in turn express and release Extracellular Vesicle (EV)-embedded antimicrobial small RNAs. These EVs can be collected from the cell-free medium of Chlorella cultures, and further concentrated and purified for biocontrol applications. Importantly, Chlorella EVs protect small RNAs from ribonuclease-mediated digestion, indicating that these lipid-based particles not only act as natural vectors of small RNAs towards pathogenic cells, but also presumably limit their degradation in the environment. The invention can thus likely be used to reduce the pathogenicity and growth of a wide range of pathogens or, potentially, to enhance beneficial effects and growth of plant-associated symbiotic and commensal microbes. Furthermore, because the integrity of Chlorella EV-embedded antimicrobial siRNAs remains unaltered when produced in photobioreactors, and when stored frozen, this method has the potential to be further exploited for the industrialization and manufacturing of a novel generation of microalgae-based biologicals.

A method for separating microalgae. The method comprises: providing a culture solution in which microalgae is cultivated, compounding iron nanoparticles on the surface of the microalgae to obtain a microalgae/iron nanoparticle composite; and performing magnetic separation on the microalgae/iron nanoparticle composite and removing the supernatant. The method uses the iron nanoparticles as a magnetic medium to separate the microalgae, does not require a complicated synthesis process, produces good adhesion to the microalgae, and the pH value of the culture solution does not need to be adjusted, and thereby overcoming problems existing in the prior art due to the use of Fe 3O4 magnetic beads as a magnetic medium to separate microalgae. The method has simple operations, low costs, mild reaction conditions, high separation efficiency, and is applicable to the magnetic separation and recovery of a variety of microalgae.
