Skincare potential of a sustainable postbiotic extract produced through sugarcane straw fermentation by Saccharomyces cerevisiae

Production of a postbiotic extract using sugarcane straw as substrate of fermentation process andSaccharomyces cerevisiae as fermentative microorganism. The extract obtained showed antioxidant and anti-inflammatory activities in skin cells, as well as beneficial for skin microbiota modulation applications. This sustainable produced postbiotic extract can be used for cosmetic and skincare ingredients development AbstractPostbiotics are defined as a “preparation of inanimate microorganisms and/or their components that confers a health benefit on the host.” They can be produced by fermentation, using culture media with glucose (carbon source), and lactic acid bacteria of the genusLactobacillus, and/or yeast, mainlySaccharomyces cerevisiae as fermentative microorganisms. Postbiotics comprise different metabolites, and have important biological properties (antioxidant, anti-inflammatory, etc.), thus their cosmetic application should be considered. During this work, the postbiotics production was carried out by fermentation with sugarcane straw, as a source of carbon and phenolic compounds, and as a sustainable process to obtain bioactive extracts. For the production of postbiotics, a saccharification process was carried out with cellulase at 55 °C for 24 h. Fermentation was performed sequentially after saccharification at 30°C, for 72 h, usingS. cerevisiae. The cells-free extract was characterized regarding its composition, antioxidant activity, and skincare potential. I...
