Microalgae and cyanobacteria as microbial substrate and their influence on the potential postbiotic capability of a bacterial probiotic.

ABSTRACT: Postbiotics are metabolic by-products from microorganisms that provide health benefits to the host. Their secretion can be influenced by various conditions affecting bacterial metabolism. This study presents a novel approach for producing potential postbiotics, specifically extracellular products (ECPs), from the probiotic strain Shewanella putrefaciens SpPdp11, grown under different culture conditions. These conditions include aquafeed media, with partial or total microalgae/cyanobacteria replacement as the microbial substrate, as well as variations in temperature and growth phase. The use of microalgae/cyanobacteria as substrates may represent a valuable strategy for generating novel postbiotics with unique properties. The ECPs assessed were evaluated for their in vitro cytotoxic, hydrol
