To analyze the phytochemical composition and in vitro antioxidant properties of aqueous extract of Aerva lanata (A. lanata) stem. During the preliminary phytochemical analysis, the aqueous extract of A. lanata was screened for the presence of carbohydrates, proteins, phenolic compounds, oil and fats, saponins, flavonoids, alkaloids, tannins and phy...

The knowledge of traditional medicine and medicinal plants and their study of scientific chemical principles may lead to the discovery of newer and cheaper drugs. Lantana camara is well known to cure several diseases and used in various folk medicinal preparations. In last few decades, scientist and researchers around the globe have elaborately stu...

This research effort aims to evaluate the hazardous potential of the redox state (OH-) of zero-valent iron nanoparticles (nZVI) and its histopathological and oxidative stress toward Mozambique tilapia, Oreochromis mossambicus. X-ray powder diffraction (XRD) validated the nZVI nanoparticles' chemical composition, while transmission electron microsco...

The biogenic method for synthesis of nanoparticles is preferred over the traditional strategies, on account of its ease, environmental friendliness, and cost-effectivity, wherein fungi endorse themselves to be the most appropriate precursor for the same. In recent times numerous metal nanoparticles have been reported to exhibit significant therapeu...

In the current scenario nanoparticles (NPs) have gained a breathtaking impetus due to their multidimensional applications in varied fields. In the present effort, biogenic synthesis of Zinc Oxide nanoparticles (ZnO NPs) was carried out using aqueous extract of dried powder of Emblica officinalis (Amla). Physicochemical characterization of nanoparti...

Bacteria from all taxa synthesize various valuable, structural, and functional polysaccharides. Bacterial polysaccharides are biodegradable, biocompatible, and naturally nontoxic biopolymers. The bacteria secrete polysaccharides into the environment. These polysaccharides are referred to as exopolysaccharides (EPS). These microbial polysaccharides...

This book presents a comprehensive overview of the use of microorganisms and microbial metabolites as a future sustainable basis of agricultural, environmental and industrial developments. It provides a holistic approach to the latest advances in the utilization of various microorganism bioprospecting including their wide range of applications, tra...

Objectives: Microbial spoilage of food is one of the leading causes of food scarcity worldwide, which could have devastating effect on the socioeconomic of any country. Along with classical food preservation methods, various innovative approaches can significantly increase the food safety. Biosurfactants are the amphiphilic microbial metabolites, w...

Objective: This study was designed to study the prevalence and antibiotic susceptibility patterns of Acinetobacter sp. as isolated from patients lodged in intensive care units (ICUs) of a tertiary care hospital, Ludhiana, Punjab, India.Methods: The clinical samples were simultaneously streaked on Blood agar and MacConkey agar. The identification of...

Urinary tract infections (UTIs) are among ten most prominent complications encountered by diabetic patients. UTIs also responsible for worsening the clinical condition of diabetic patients by causing damage tothe urinary tract. During the study, a total of 67 urine samples were collected from (different age groups and both gender) the diabetic pati...

Present study was aimed to analyze berberine concentration in Tinospora cordifolia stems collected from Ficus, Azadirachta, Syzygium, Populus and Eucalyptus. High Performance Liquid Chromatography equipped with UV detector was used for analytical study of berberine from the stem of Tinospora cordifolia. Methanol (100%) as a diluent was used for...

Urinary tract infection (UTI) is a very common and prevalent type of bacterial infection in females, therefore current study was designed to investigate the prevalence of microorganisms in female UTIs cases and their resistance patterns. During the study, a total of 281 urine samples were collected from females clinically suspected for urinary trac...

Present study is focused on the synthesis of titanium dioxide nanoparticles (TiO2 NPs) from marine actinobacteria and to check their antibiofouling activity against the isolated biofouling bacteria. A total of five actinobacterial strains were isolated from Chennai marine sediments, Tamilnadu, India, which were designated as SV1-SV5. Two biofouling...

In the present work, we describe a low-cost, unreported and simple procedure for biosynthesis of zinc oxide nanoparticles (ZnO NPs) using reproducible bacteria, Aeromonas hydrophila as eco-friendly reducing and capping agent. UV-vis spectroscopy, XRD, FTIR, AFM, NC-AFM and FESEM with EDX analyses were performed to ascertain the formation and charac...

The purpose of the present study was to assess the effect of crude extracts of marine actinobacteria on larvicidal, repellent, and ovicidal activities against Culex tritaeniorhynchus and Culex gelidus (Diptera: Culicidae). The early fourth instar larvae of C. tritaeniorhynchus and C. gelidus, reared in the laboratory, were used for larvicidal, ovic...
