Antibacterial Action of Bacillus coagulans Against Diverse Pathogens and its Relevance as Probiotics
Abstract: Probiotics are living organisms that give benefits to the host organism by improving the intestinal microbial balance. Probiotics have various beneficial effects as it maintains a healthy gut, healthy vaginal flora and boost the immune system. There are different strains of lactic acid bacteria that are used as probiotics but Bacillus coagulans is a good bacterium that is used in the form of probiotic supplements. In the present study, B. …

Characterization of Antibacterial and Biofilm Inhibition in Tin and Zinc Oxide Nanoparticle-Doped Orthodontic Composites
Abstract: Background: This study investigated the antibacterial effectiveness of orthodontic adhesive enhanced with stannous oxide (SnO₂) nanoparticles against Lactobacillus acidophilus and Streptococcus mutans, in comparison to traditional adhesives without nanoparticle infusion. Methods: A modified orthodontic adhesive was prepared by incorporating 1% w/w of tin dioxide and zinc oxide nanoparticles (SnO₂ + ZnO₂ NPs) into Transbond XT. This nanoparticle-enhanced composite was used to fabricate discs for assessing antibacterial activity against Lactobacillus acidophilus …

Exploring the Bioactive Potential of Himalayan Lichens: Phytochemical and Antimicrobial Profiling of Xanthoparmelia tinctina and Pyxine subcinerea Extracts
Abstract: The symbiotic association that develops between cyanobacteria, algae, and fungi results in the composite organism known as lichens, which has traits similar to those of plants but differs in its separate parent organisms. Lichens can have a variety of morphological characteristics, including foliose structures that resemble flat leaves, crustose structures that resemble flake crystals, fruticose branches that have short, leafless branches, and leprose-powder-like appearances. Due to their therapeutic potential, lichens …

Antibacterial, Cytotoxicity Studies of Azukia mungo (L.) Masam and Correlation with in silico Docking Studies
Abstract: Introduction and Background: Azukia genus plants rich in proteinaceous anti-nutrients like tannins (especially condensed tannins) has been shown to have anti-bacterial activity against Staphylococcus aureus and antineoplastic activity against lung and liver cancer cells. Five types of procyanidins (condensed tannins) have already been isolated from Azukia mungo and structurally elucidated. But its activity against the Methicillin resistant Staphylococcus aureus (MRSA) has not yet been shown. Hence we focus our work …

Nitric-oxide Scavenging Antioxidant Activity of the Different Extracts of Plumeria obtusa (Family:Apocynaceae)
Abstract: Plumeria obtusa (Family-Apocynaceae) has a long ethnomedicinal tradition of being used as a remedial agent in various diseases such as diarrhoea, piles, fever, gonorrhoea, antibacterial and antitumour agents etc. Antioxidant potential of the crude petroleum ether, chloroform and methanol extracts of the leaf and bark were evaluated by using nitric oxide scavenging assay. The extracts showed significant activities compared to ascorbic acid in a dose dependent mode. Moreover, the percentage …

Green Synthesis and Characterization of Silver Nano-conjugates Using Heliotropium indicum and Glycosmis pentaphylla Leaf Aqueous Extracts
Abstract: Heliotropium indicum Linn. (Family Boraginaceae), an annual herbaceous medicinal plant, is usually known as Indian heliotrope. Glycosmis pentaphylla (Retz.) DC (Family Rutaceae) is a perennial shrub, commonly known as orange-berry. These traditionally used medicinal plants originate from tropical and temperate parts of the world along with India, Southeast Asia, Northern Australia, and some other African countries. Extensive literature studies suggested that the different parts of the plant are reported to …

Preparation and Characterization of Clay-Based Hybrid Membranes for Antibacterial Biodegradable Polymer Wound Dressings
Abstract: Recent developments in the field of polymer chemistry have resulted in many new forms of Hybrid polymer. This has further revolutionized the application of polymer chemistry in numerous fields. In this research, we manufactured clay-based hybrid membrane by adding clay to the biodegradable matrix of chitosan polymer. It is widely known that microbial and pathogenic organisms are responsible for wound hampering infections such as impetigo. They can spread in bodily …

Promising Antimicrobial Compounds from an Endophytic Fungus Penicillium daleae EF 4 Isolated from the Seaweed Enteromorpha flexuosa Linn.
Abstract: AbstractThe present aim of the study is to isolate the endophytic fungi from various seaweeds and to screen their bioactivity, to analyze the β-lactamase inactivator and to evaluate the interactions between the crude extract of Endophytic fungi Penicillium daleae EF 4 and two antibiotics (penicillin G and tetracycline), against some antibiotic resistant bacterial strains. Seaweeds collected from various places of Bay of Bengal coast was subjected to Endophytic fungal isolation. …

Novel Modified Chitosan/Clay Nanocomposites with Antimicrobial Activity
Abstract: Unmodified sodium montmorillonite (Na-MMT) and montmorillonite modified by poly(methylmethacrylate) (PMMA) were used to intercalate chitosan (CS) and chitosan blended with polytertahydrofuran (CS-PTHF750). Their structures were characterized by XRD, TEM and IR techniques. The results showed that CS and CS-PTHF750 chains were inserted into silicate layers. The interlayer distance of the layered silicates in the nanocomposites enlarged as the amount of polymer increased. The thermal stability of the nanocomposites is characterized …

Antimicrobial Susceptibility Profile of Airborne Bacteria and Fungi at Owena Market, Osun State, Nigeria
Abstract: Environmental conditions and human activities influence the ubiquity and diversity of microorganisms in the atmosphere thereby acquiring the ability to resist antibiotics which poses serious public threat. Airborne bacteria and fungi isolated using settling plate method from three different points (where kolanuts, meat and onions are sold) at Owena Market, Osun state, Nigeria were assayed for antimicrobial susceptibility using disc diffusion. The microorganisms were identified as Staphylococcus aureus, Bacillus subtilis, …
