Research ArticleOpen accessIn the abstractAntibacterial and Anti-Quorum Sensing Activities of Selected Italian Honeys against Antibiotic-Resistant PathogensMarco Fidaleo, Roberto Lavecchia, Antonio ZuorroThree nectar honeys (eucalyptus, thyme and forest) and two honeydew honeys (fir and Metcalfa) from Italy were tested for their antibacterial activity against pathogens commonly associated with wound and burn infections, including Methicillin-Resistant Staphylococcus Aureus (MRSA), methicillin-resistant Staphylococcus epidermidis (MRSE) and Vancomycin-Resistant Enterococcus Faecalis (VREF). All honeys showed bactericidal activity against the microorganisms used, with honeydew honeys being the most … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 27 Oct 2015 · 7,050 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study on Bioelectricity Production by the Synergistic Action of Bacillus tequilensis DMR-5 and Pseudomonas aeruginosa DMR-3 Isolated from Rumen FluidJothinathan Deepika, Sundaram Meignanalakshmi, Wilson Richard ThilagarajThe present study focuses on the bioelectricity production from pure culture of Bacillus tequilensis DMR-5 and Pseudomonas aeruginosa DMR-3. Both the cultures were isolated from the anodic biofilm of pre-run MFC’s with rumen fluid as anodic substance. They were checked for the power production for 10 days both as pure isolates and co-culture. Bacillus tequilensis and Pseudomonas aeruginosa produced 250 … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 29 Oct 2013 · 6,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysicochemical and Microbial Caracteristics Performency in Wastewater Treated Under Aerobic ReactorAsma Ben Rajeb, Hamadi Kallali, Neila Saidi et al.Problem statement: The current work study the efficiency of biological wastewater treatment by an aerobic reactor which could be used in small agglomerations. RBC reduced physicochemical and microbiological load of wastewater but values remain above Tunisian standard. Approach: Experiments were conducted on a sand filled PVC column fed with wastewater treated by Rotating Biological Contactor (RBC) at a pulsed rhythm … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractExogenous Pyocyanin Alters Pseudomonas aeruginosa Susceptibility to CiprofloxacinGary D. Grant, Tian Tian Zhang, Lee S. Gloyne et al.This in vitro cell-based study identified the contributing role of pyocyanin in the resistance of Pseudomonas aeruginosa to ciprofloxacin. Problem statement: P. aeruginosa is the major pathogen in the Cystic Fibrosis (CF) lung with pyocyanin being a critical component of its virulence. Prevalence is high and, once acquired, chronic infection is difficult to eliminate. Ciprofloxacin remains a crucial oral agent … …Current Research in Microbiology, Vol. 1, Issue 1 · 30 Jun 2010 · 8,792 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytocompatibility and Antimicrobial Properties of Silver Nanoparticles-Loaded AMPs in the Oral CavityYanli Lv, Weikai ZhangPostoperative infection following oral metal implantation is a key factor that affects the success rate of surgery. This infection is mainly caused by bacterial biofilms. Traditional single antibacterial coatings have limitations, including a narrow antibacterial spectrum and poor cytotoxicity or stability. This study combined silver nanoparticles (AgNPs) and the synthetic antimicrobial peptide GL13K using electrostatic self-assembly technology to create a … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 24 Apr 2026 · 1,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Properties of Biopolymers from Corn Starch with Addition of Microalgae Spirulina platensisJúllia Koury Abreu, Loraynne Coelho Pereira, José Izaquiel Santos da SilvaThe discovery of the environmental impacts caused by petroleum-based polymers has led to the use of natural polymers gaining more and more space. Naturally occurring polymers, also known as biopolymers, are chemical compounds produced by living things or raw materials from renewable energy sources. Their main advantage is decomposition, while polymers from fossil and non-renewable energies can take hundreds of … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 1 · 16 Mar 2023 · 6,026 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout the Cyanobacteria and StromatolitesFlorian Ion Tiberiu Petrescu, Liviu Marian UngureanuStromatolites are layered biochemical accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains in biofilms (specifically microbial mats), especially cyanobacteria. Stromatolites occur widely in the fossil record of the Precambrian but are rare today. Life on Earth was born at least 3.7 billion years ago, but since then the number of living things has … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 17 Feb 2022 · 8,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Mercury from chlor-alkali Industry Wastewater using Acetobacter xylinum CelluloseA. Rezaee, J. Derayat, S. B. Mortazavi et al.In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function of pH, adsorbent dose and contact time. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 8,283 accessesView PDFCite
