Keywords: | microbial biotechnologies, new antioxidant extracts | Issue Date: | 2023 | Conference: | UGAL Invent 2023 | Abstract: | The invention relates to microbial biotechnologies, specifically to obtaining of new antioxidant extracts based on pigments from Arthrospira platensis cyanobacteria biomass, a residue from the production of the BioR remedy. The essence of the invention is the proposal of a new process for obtaining antioxidant extracts based on pigments from Arthrospira platensis cyanobacteria. The remaining biomass, dried at the temperature of +50±5°C, is ground, and mixed with 96% ethyl alcohol in the 1:10 v/v ratio. The suspension is supposed to sonication (50 W) for 5 minutes or placed in a water bath at the temperature of +45°C for 30 minutes with periodic stirring. At the end of the process, the extract is separated from the biomass by centrifugation at 3500 rpm. for 5 minutes. To obtain of the concentrated extract, the ethyl alcohol is removed using a rotary evaporator. |
