One of such mechanisms is exopolysaccharides, which are secreted by marine prokaryotes to interact with surface proteins of viral particles and prevent the binding of viral peplomers to receptors of potential target cells. Therefore, antiviral drugs with a wide spectrum of actions, exhibiting also the ability to modulate intercellular interactions, are found in large numbers among exopolysaccharides of marine bacteria. This review analyzes the modern views on exopolysaccharides of marine bacteria, their antiviral potential, and antioxidant and immunomodulatory activity. A brief description of the structural, physical, and chemical properties of such compounds is given and the main mechanisms of antiviral activity of the best-known representatives of this class of organic polymers are disclosed. Exopolysaccharides of marine bacteria are shown to be a promising and extremely rich source of antiviral medicinal substances.</p>","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141720881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compare the effect of nanoparticles on bacteria to that of known toxicants in several experiments to determine the growth characteristics and activity of enzymes on nutrient media and also their adhesion to human red blood cells. The following concentrations of toxicants were used: sodium selenite and potassium tellurite, 100 μg/mL; copper sulfate, 10 μg/mL; and selenium and tellurium nanoparticles, 100 μg/mL. We found that nanoparticles mainly inhibited the proteolytic, lipolytic, amylase, DNase, and hemolytic activities, whereas copper ions stimulated them. Selenium nanoparticles inhibited the pigment synthesis in <i>Pseudomonas aeruginosa</i> and <i>Staphylococcus aureus</i>. Nanoparticles and soluble forms of selenium and tellurium suppressed the bacterial adhesion to human red blood cells, while copper ions stimulated it. We also assessed the possible environmental risks of the emergence/use of the studied toxicants in the marine environment using an <i>Artemia salina</i> model. Based on the analysis of selenium and tellurium nanoparticles, we could classify them as nontoxic compounds, and sodium selenite, potassium tellurite, and copper sulfate, as toxic ones.</p>","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141720884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate a pronounced tissue specificity of the scallop AO complex along with close levels of TBA-reactive substances in all the studied organs. In the gills of the scallop, the activity of glutathione reductase (GR), superoxide dismutase (SOD), and catalase is higher than in the hepatopancreas. The activity of glutathione peroxidase (GP), GR, and catalase in the gills is higher than in the muscle. The reduced glutathione (GSH) reserve in the gills is lower than in the hepatopancreas. This indicates that both the glutathione system and the key antioxidant enzymes, SOD and catalase, significantly contribute to the antioxidant defense of the scallop gills. In the hepatopancreas, the level of glutathione is the highest and the activity of GP is high and similar to that in the gills. This reflects their significant role in the AO defense of this organ. However, the activity of GR, SOD, and catalase in the hepatopancreas is significantly lower than in the gills. The scallop muscle is characterized by the lowest GP activity and a low GSH level, close to that in the gills. The SOD activity in the muscle is comparable to its value in the gills, and the activity of catalase and GR is comparable to the values in the scallop’s hepatopancreas.</p>","PeriodicalId":49584,"journal":{"name":"Russian Journal of Marine Biology","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141720883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
