Enzymatic and non-enzymatic bioactive compounds, and antioxidant and antimicrobial activities of the extract from one selected wild berry (Rubus coreanus) as novel natural agent for food preservation

Oxidative Stress-Mediated Repression of Virulence Gene Transcription and Biofilm Formation as Antibacterial Action of Cinnamomum burmannii Essential Oil on Staphylococcus aureus

“…Given that a similar accumulative pattern of MDA (Figure 4A) and ROS (Figure 4B) in CBLEO-treated S. aureus cells was positively associated with the degree of bacterial growth inhibition, material release, and cell membrane damage (Figures 1-3), it seems certain that CBLEO-induced oxidative stress may be one crucial bactericidal effect. Our results were consistent with the effect of the essential oils from different plants and natural compounds (such as carvacrol, citral, flavonoid, anthocyanin, dihydromyricetin, and eugenol) on S. flexneri, S. aureus, E. coli, and P. digitatum [7,8,14,16,17,19,28,55,56] and also evidenced by previous studies showing that the effects of antibacterial agents (such as fluconazole, cerulein, catechin, chitosan, miconazole, indomethacin, and hypocrellin A) could cause oxidative stress with the consequence of ROS accumulation and membranous damage destined for bacterial cell death [44,[57][58][59][60].…”

Excitation of Reactive Oxygen Species and Damage to the Cell Membrane, Protein, and DNA are Important Inhibition Mechanisms of CO2 on Shewanella putrefaciens at 4 °C

“…Compared with Figures A–C and S1C, the testing results of T-AOC were mainly consistent with the ROS scavenging activity and concentration of GSH, which synergistically proved that a weaker defensive system was caused by CO 2 . Chen et al also demonstrated that there was a positive correlation between T-AOC and ROS scavenging ability.…”

“…coli were accompanied by accumulated ROS. According to Chen et al, more carbonyl content and MDA accumulation in Salmonella enteritidis was proved to be positively associated with the concentration of ROS. In this research, corresponding higher levels of lipid peroxidation and cell membrane damage were also observed in the pure CO 2 group, as shown in Figure A–D.…”

“…Therefore, the expression of protein and extracellular protease was disturbed and presented an inverse relationship with more accumulation of ROS. Chen et al also demonstrated that accumulated ROS caused by oxidative stress led to protein oxidation and eventually resulted in cell death.…”

New Trends in Supercritical Fluid Technology and Pressurized Liquids for the Extraction and Recovery of Bioactive Compounds from Agro-Industrial and Marine Food Waste

“…Discovering that Nordic microalgae are a potential source of carotenoids such as neoxanthin, violaxanthin, antheraxanthin, lutein, c-lutein, astaxanthin, β-carotene, chlorophyll b, chlorophyll a, polyphenols and compounds with antioxidant activity [134]. Also, were investigated wild Berry Rubus coreanus as a new source of bioactive compounds with antioxidant and antimicrobial activity against pathogenic bacteria such as S. enteritidis, V. cholerae, E. coli, S. barbata, S. typhimurium, and S. aureus [135].…”
