Abstract:

Biocidal activities of monochloramine and peracetic acid were studied on cysts of Naegleria lovaniensis. Until recently the most commonly used biocide to disinfect cooling water systems was hypochlorite. Owing to its negative impact on the aquatic environment, ecologically less harmful alternatives have been sought. As the biocidal activity of monochloramine and peracetic acid makes them good candidates for inactivation of pathogenic Naegleria species, these biocides were tested against Naegleria lovaniensis, a relative of the pathogen Naegleria fowleri, as an alternative treatment to hypochlo

Abstract:

ABSTRACTThe main aim of this study was to develop a standardized experimental assay to enable differential antimicrobial comparisons of test biocidal aerosols. This study represents the first chlorine-matched comparative assessment of the antimicrobial activities of aerosolized sodium hypochlorite, chlorine dioxide, and electrochemically activated solution (ECAS) to determine their relative abilities to decontaminate various surface-associated health care-relevant microbial challenges. Standard microbiological challenges were developed by surface-associating typedPseudomonas aeruginosa,Staphyl

Synthetic chemicals are used to protect crops and agricultural products, thereby producing high yields. However, intensive use of these synthetic chemicals significantly affects the environment and sustainable agriculture production. Moreover, direct or indirect exposure to these synthetic chemicals may cause acute or chronic toxicity in humans and animals. Due to their biodegradability, low toxicity, and being environmentally friendly, secondary metabolites derived from plant sources are being studied as a sustainable approach.

ABSTRACT Bacteria and matrix are essential for the development of biofilms, and assays should therefore target both components.

Abstract:

In this study we identified the expression patterns of β-defensin-9 in chickens from Saudi Arabia, evaluated the antimicrobial activities of synthetic chicken β-defensin-9 (sAvBD-9) against pathogenic bacteria and fungi, and investigated the mode of action of sAvBD-9 on bacterial cells. The AvBD-9 gene of Saudi chickens encodes a polypeptide of 67 amino acids, which is highly similar to the polypeptide in duck, quail, and goose (97%, 86%, and 87%, respectively) and shares a low sequence similarity with the mammalian defensins. AvBD-9 is expressed in various organs and tissues of Saudi chickens

Abstract:

There is a growing interest in new type of biocidal compounds with antibacterial properties against bacteria. In this study, new antibacterial synthetic materials bearing curcumin and cationic polymers were synthesized. In the synthesis stage, the methacrylate functional cationic monomer was synthesized via the Michael addition route by using 3-acryloxy-2-hydroxypropyl methacrylate and 3-amino pyridine to obtain Monomer 1. Monomer 1 was further quaternized with hexyl bromide to obtain a cationic methacrylate functional monomer. Free-radical polymerization of Monomer 1 and methyl acrylate was c

Abstract:

7-Hydroxy-3',4'-methylenedioxy- and 7-benzyloxy-3',4'-methylenedioxy flavanones have been synthesized starting from 2,4-dihydroxyacetophenone. Subsequently biocidal activities of the flavanones have been investigated along with their corresponding chalcones against some bacterial and fungal strains. 2'-Hydroxy-4'-benzyloxy-3,4-methylenedioxy chalcone (5) and its corresponding flavanone (7) showed good antibacterial and antifungal activities against some selected bacterial and fungal strains. On the other hand, 2',4'-dihydroxy-3,4-methylenedioxy chalcone (4) showed no antibacterial and antifung

<strong>Abstract </strong> <strong>Objective -</strong> <em>Literature survey indicates that hydrazine the simplest diamine, is known to form fairly stable complexes with mineral and carboxylic acids. Among the different substituted dicarboxylic acids, the potential tridentate α-amino dicarboxylic acid such as aspartic acid has been found to exhibit a strong interaction towards metal ions. Though the interaction of aspartic acid with aromatic amines, imidazole, bipyridine and phenanthroline towards various metals has been well studied, the studies with simple diamine, hydrazine with the

Abstract:

Microalgae-mediated synthesis of nanoparticles (NPs) is an emerging nanobiotechnology that utilizes the biomolecular corona of microalgae as reducing and capping agents for NP fabrication. This study screened a novel microalgal strain for its potential to synthesize silver (Ag)-NPs and then assayed the biological activities of the NPs. Coelastrella aeroterrestrica strain BA_Chlo4 was isolated, purified, and morphologically and molecularly identified. Chemical composition of the algal extract was determined by GC-MS analysis. Ag-NPs were biosynthesized by C. aeroterrestrica BA_Chlo4 (C@Ag-NPs)
