The current study describes the application of the marine probiotic Enterococcus durans E23 for fermenting and biologically extracting Ulva fasciata . The prepared extract (RE) exhibited promising antibacterial activity against Pseudomonas fluorescens , Enterococcus faecalis , Klebsiella pneumoniae , E. coli , Bacillus sp., and Staphylococcus aureus (inhibition zone diameters 10–21 mm). Total phenolics, flavonoids, and GC–MS a...

Nattokinase (NK), a protease enzyme produced by Bacillus subtilis , has various biological effects such as lipid-lowering activity, antihypertensive, antiplatelet/anticoagulant, and neuroprotective effects. Exposure to environmental toxicants such as bisphenol A (BPA) or γ-radiation (IR) causes multi-organ toxicity through several mechanisms such as impairment of oxidative status, signaling pathways, and hepatic and neuronal f...
