Functional probiotic attributes of Bacillus subtilis ULB16, an endophyte isolated from marine macroalga, Ulva lactuca
Marine-derived probiotics offer a compelling alternative to traditional antibiotics in aquaculture, and *Bacillus subtilis* ULB16, an endophyte isolated from *Ulva lactuca*, demonstrates significant promise. This study validates its probiotic potential, revealing tolerance to gastrointestinal stressors and notable interactions with both enteric and aquaculture-associated pathogens. Furthermore, the isolate exhibits β-galactosidase activity, suggesting added nutritional benefits. These findings, alongside its biofilm-forming ability and epithelial adhesion, collectively position *B.

Genome-wide characterization of hemocyanin gene family and adaptive evolution of heme oxygenase across four penaeid shrimp species
Penaeid shrimp aquaculture faces escalating challenges from disease and environmental stress, highlighting the critical need for enhanced resilience. This study presents a comprehensive, genome-wide characterization of the hemocyanin gene family across four penaeid shrimp species, alongside an analysis of heme oxygenase (HO) adaptive evolution. Phylogenetic analysis revealed key divergence times, with *Marsupenaeus japonicus* exhibiting the earliest separation. The research identifies a significantly expanded hemocyanin gene repertoire and pinpoints HO, demonstrably under positive selection, as playing a vital role in immune defense and stress tolerance.
