Antibacterial Activity of Silver Nanoparticles of Seaweeds

  title={Antibacterial Activity of Silver Nanoparticles of Seaweeds},
  author={B.Vasudeva Rao and Meganathan Boominathan},
  journal={American Journal of Advanced Drug Delivery},
In the present study, antibacterial activity of silver nanoparticles synthesized from the seaweeds of Ulothrixflacca, Ulva fasciata and Caulerpataxifolia were analyzed against four gram positive and gram negative bacterial strains of common fish and human pathogens. As these pathogens cause enormous damage to aquaculture as well as pose harmful threat to humans and their emergence as multidrugresistant strains is a major problem in the control of infections. Further antibacterial activity of…

Synergistic and Antagonistic Effects of Metal Nanoparticles in Combination with Antibiotics Against Some Reference Strains of Pathogenic Microorganisms
AgNPs and ZnONPs demonstrate a good synergistic effect with antibiotics and this may open the door for a future combination therapy against pathogenic bacteria.
The Preventive Effects and Mode of Actions of Ulva Fasciata Synthesized Silver Nanoparticles in Doxorubicin-Induced Hepatotoxicity in Wistar Rats
It can be concluded that U. fasciata counteracts doxorubicin-induced toxicity by suppression of inflammation, oxidative stress and apoptosis and was the most potent in improving hepatocyte integrity and liver histological architecture.
Characterization of Ulva fasciata Ethanolic Extract-mediated Biosynthesized Silver Nanoparticles and Evaluation of their Nephrocadiopreventive Effects in Doxorubicin-injected Wistar Rats
U. fasciata, which is more potent, could have preventive effect against doxorubicin-induced renocardiotoxicity in Wistar rats and this effect could be mediated, at least in part, via enhancement of the antioxidant defense system.
Photocatalytic Activity of Revolutionary Galaxaura elongata, Turbinaria ornata, and Enteromorpha flexuosa’s Bio-Capped Silver Nanoparticles for Industrial Wastewater Treatment
Silver nanoparticles are stabilized and capped with bioactive compounds such as Galaxaura elongata, Turbinaria ornata, and Enteromorpha flexuosa from marine macroalgae extracts to produce Ag[GE], Ag[TE], and Ag[EE] NPs which were applied to photodegrade hazardous pigments under sunlight irradiation.
Control of Virulent Listeria monocytogenes Originating from Dairy Products and Cattle Environment Using Marine Algal Extracts, Silver Nanoparticles Thereof, and Quaternary Disinfectants
P. pavonica extract showed promising antimicrobial properties, calling for further comprehensive studies prior to it being applied in the food industry to enhance the safety, quality, and shelf life of products and protect public health.


Antimicrobial effects of silver nanoparticles.
Antimicrobial Activities of the Extracts of Marine Algae from the Coast of Urla (İzmir, Turkey)
Diethyl ether was the best solution for extracting the effective antimicrobial materials from the algae species used in this experiment, with the exception of D. linearis, for which ethanol was the most effective extraction solution.
An Assessment of the Antioxidant and Antimicrobial Activity of Six Species of Edible Irish Seaweeds
It was found that dried methanolic extracts of red and green seaweeds had significantly lower antimicrobial activity than the brown species; H. elongata had the highest antimacterial activity with up to 100% inhibition.
Effect of proteins from the red seaweed Hypnea musciformis (Wulfen) Lamouroux on the growth of human pathogen yeasts
The complete growth recovery following fetuin treatment indicated that chitinase and b-1,3-glucanase were not involved in the growth inhibition of these yeasts, and the inhibitory action was shown to be fungistatic and the presence of the glycoprotein fetuin abolished the antifungal action.
Antibacterial activities of some marine algae from the Aegean Sea (Turkey)
In this study, methanolic extracts of six marine algae belong to Rhodophyceae (Corallina officinalis), Phaeophyceae (Cystoseira barbata, Dictyota dichotoma, Halopteris filicina, Cladostephus
Antibacterial activity of extracts of six macroalgae from the northeastern brazilian coast
Hexane, chloroform and ethanol extracts of six marine macroalgae from North Ceara coast (Northeast Brazil) were evaluated for antibacterial activity by the single disk method and best results were shown by the hexane extracts of Amansia multifida against enteric Gram-negative strains.
Antagonistic activity of marine actinomycetes from Arabian Sea coast
The sponge-microbial association is a potential chemical, ecological phenomenon, which provides sustainable source of supply for developing novel pharmaceutical leads, and counts of actinomycetes were found maximum in sponges during south west monsoon season.
Wound management in an era of increasing bacterial antibiotic resistance: a role for topical silver treatment.
The silver-coated dressing was particularly rapid at killing the tested bacteria and was effective against a broader range of bacteria, with silver nitrate being the most efficacious andsilver nitrate the least efficacious.
