Resumen de: US2024294864A1
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 and system for monitoring invasive species in an algal bioreactor utilizes a low resolution Raman spectrometer (LRRS) system and signal processing methods based upon Support Vector Machine (SVM) models. A spectrum preprocessing algorithm transforms LRRS spectra into normalized spectral data vectors. An ex-situ method is used to analyze a calibration set of known samples of a suspension containing a desired biomass, such as spirolina, together with various concentrations of invasive algal or cyanobacterial species. The ex-situ method generates SVM models and their associated SVM support vectors for classification modeling. An in-situ method uses the SVM models to provide an output vector of probability values corresponding to the presence of invasive species in an unknown sample, and optionally to provide an additional output vector of probability values corresponding to concentrations of the invasive species in the unknown sample.
