“…The use of these compounds is common due to their high safety and lack of toxicity [104]. These chemical compounds have biological activities beneficial to humans, including anti-inflammatory [105], anticancer [106], prevention and treatment of diabetes [107], and beneficial effects on the immune system [108]. Antioxidants act by inhibiting free radical reactions, suppressing oxidative processes, and avoiding consequent cell damage [109].…”

The food industry produces an exorbitant amount of solid waste of petrochemical origin as a result of the increase in the development of new products. Natural polymers are an alternative to this theme; however, their development with adequate properties is a challenge. The union of different polymers in the synthesis of packaging is usually carried out to improve these properties. The combination of agar-agar and chitosan biopolymers show particular advantages through hydrogen bonds and electrostatic attraction between oppositely charged groups, presenting a promising source of studies for the synthesis of green packaging. When combined with natural extracts with active properties, these polymers allow an increase in the microbiological stability of foods associated with lower chemical preservative content and greater environmental sustainability.

Pseudoalteromonas piscicida 2515, isolated from Litopenaeus vannamei culture water, is a potential marine probiotic with broad anti-Vibrio properties. However, genomic information on P. piscicida 2515 isscarce. In this study, the general genomic characteristics and probiotic properties of the P. piscicida 2515 strain were analysed. In addition, we determined the antibacterial mechanism of this bacterial strain by scanning electron microscopy (SEM). The results indicated that the whole-genome sequence of P. piscicida 2515 contained one chromosome and one plasmid, including a total length of 5,541,406 bp with a G+C content of 43.24%, and 4679 protein-coding genes were predicted. Various adhesion-related genes, amino acid and vitamin metabolism and biosynthesis genes, and stress-responsive genes were found with genome mining tools. The presence of genes encoding chitin, bromocyclic peptides, lantibiotics, and sactipeptides showed the strong antibacterial activity of the P. piscicida 2515 strain. Moreover, in coculture with Vibrio anguillarum, P. piscicida 2515 displayed vesicle/pilus-like structures located on its surface that participated in its bactericidal activity, representing a novel antibacterial mechanism. Nevertheless, 16 haemolytic genes and 3 antibiotic resistance genes (tetracycline, uoroquinolone, and carbapenem) were annotated, but virulence genes encoding enterotoxin FM (entFM), cereulide (ces), and cytotoxin K were not detected. Further toxicity tests should be conducted to con rm the safety of P. piscicida 2515. The results here provide a new understanding of the probiotic properties and antibacterial mechanism of P. piscicida 2515 and theoretical information for its application in aquaculture.
