This study employs genomic and comparative analyses to search into the strain's genetic profile, safety features, and probiotic attributes. The safety assessment reveals the absence of virulence factors and antimicrobial resistance genes, while the genome uncovers bacteriocin-related elements, including sactipeptides and a cluster for putative plantaricins, strengthening its ability to combat diverse pathogens.

The films and coatings are intended for application as coating materials for mango fruits. Due to the good miscibility between native cassava starch and cationic cassava starch, the starch blend film was more hydrophobic than films produced from unblended native cassava starch and unblended cationic cassava starch.

To test carotenoid production, selected strains were cultivated in basic isolation medium (BIM), glutamate acetate medium, G5 medium and artificial acetic acid wastewater (AAW) medium. From 144 PNSB, Rhodopseudomonas palustris KTSSG46 was selected to produce carotenoids under microaerobic light conditions in BIM.

The disease is typically moderated by the use of antibiotics. To investigate the control of AHPND and maintenance of water quality without the use of antibiotics, the supplementation of shrimp feed with anti-vibrio compounds from a crude extract of probiotic Rhodobacter sphaeroides SS15 was evaluated.
