Abstract:
Fungus belonging to the genus Aspergillus is considered highly important in the production of various types of enzymes and organic acids. Aspergillus species produce organic acids such as citric acid, itaconic acid, and malic acid, which are one of the most important alternate techniques for chemical processes. Citric acid is an important component in the manufacturing process of food and beverages, pharmaceuticals, cosmetics, toiletries, detergents, and other industries. In this work, A.niveus was isolated from the agricultural waste collected in Kotagiri, The Nilgiris, India. Submerged batch fermentation with a range of low-cost substrates, such as wheat flour, corn starch, and sweet potato, was used to successfully synthesize citric acid by the isolated fungus. In addition, production-related factors such as substrate concentration and incubation time were optimized. The maximum yield of citric acid was produced using A. niveus from corn starch at a concentration 7of 120 g/L after 168 hours at pH 3.2. Furthermore, with a degree of extraction of 91.96, citric acid was extracted from fermentation.

Abstract:
The Electrochemical Promotion of Catalysis (EPOC) or Non-Faradaic Electrochemical Promotion of Catalysis (NEMCA effect) is a phenomenon observed as a reversible change in catalytic rate (i.e. no net charge transfer rate) of a chemical reaction occurring on a catalyst film (or supported dispersed catalyst) deposited on an ionically conducting or mixed electronically-ionically conducting solid electrolyte support upon the application of an electrical potential between the catalyst and a second conductive film deposited on the solid electrolyte support.

Abstract:
For the first time, this research has developed an efficient and novel approach to high to excellent yields for synthesizing Quinazolinone derivatives. Also, the synthesis of Quinazolinone derivatives has been carried out in the presence of [email protected]/La2O3 nanocomposite as a novel heterogeneous catalyst and a green under solvent-free conditions and in a short time and excellent yields for the first time. Various structural and morphological characteristics of the nanocatalyst were employed for the catalyst characterization, such as FT-IR, XRD, FE-SEM, EDX and VSM analyses. All characterization data were checked with each other so that the structure of the nanocatalyst was exactly characterized. The reactions were carried out in the presence of a low amount of nanocatalyst at 100 °C under solvent-free conditions for a short period of time. The proposed nanocomposite exhibits excellent catalytic activity. One of the most important advantages of this method is easy magnetic nanocatalyst separation, green condition, excellent recoverability and easy workup.

Abstract:
As a vital index of the mitochondrial micro-environment, mitochondrial micro-viscosity plays a fundamental role in cell life activities. Normal mitochondrial viscosity is a necessary condition for the maintenance of normal life activities of mitochondria. Abnormal mitochondrial viscosity can lead to a series of mitochondria-related diseases. Therefore, it is essential to observe mitochondrial viscosity for physiological and pathological processes. Given the conventional viscosity measurement methods (viscometer, etc.) cannot monitor the changes in mitochondrial viscosity, the fluorescence method supplemented with the fluorescent probe is widely used to observe the changes in mitochondrial viscosity. In view of the booming development in this area, this review describes the applications of viscosity-responsive mitochondrial fluorescent probes in biological samples from the cellular and tissue levels. We hope that this review will deepen our understanding of mitochondrial viscosity and related fields, and promote the development of viscosity-sensitive mitochondrial probes and other organelle fluorescence probes.

Abstract:
Nanotechnology is starting the characterization, fabrication, and possible applications of numerous materials at the Nano-scale. Over the last few eras, nanomaterials provide a platform for researchers from diverse arenas due to the high surface-to-volume ratio and other novels, and new significant belongings. Zinc oxide nanoparticles are receiving diverse biomedical applications because of their distinctive antimicrobial, antioxidant, anticancer, antifungal, antileishmanial, anti-larvicidal, wound healing, anticholinergic, and anti-diabetic properties. Different physical and chemical approaches have been used to synthesize zinc oxide nanoparticles, but these methods cause ecotoxicity and are time-consuming and costly. Therefore, there is a need for more eco-friendly, cost-effective, and safe methods. Such biogenic Zinc oxide nanoparticles offer more advantages over other physiochemically synthesized methods. In this review, we have summarized the recent literature for the understanding of the green synthesis of Zinc oxide nanoparticles, their characterization, and their various biomedical applications.

Abstract:
Today HPLC is widely applied for separations and purifications in a variety of areas including pharmaceuticals, biotechnology, environmental, polymer and food industries. It is accomplished by injection of a small amount of liquid sample into a moving stream of liquid (called the mobile phase) that passes through a column packed with particles of the stationary phase. The separation of a mixture into its components depends on different degrees of retention of each component in the column. HPLC is just one type of liquid chromatography, meaning the mobile phase is a liquid. Reversed-phase HPLC is the most common type of HPLC. The reversed-phase means the mobile phase is relatively polar, and the stationary phase is relatively non-polar. HPLC instrumentation includes a Solvent reservoir, pump, injector, column, detector, and integrator or acquisition and display system. The heart of the system is the column where separation occurs. The information that can be obtained using HPLC includes identification, quantification, and resolution of a compound. The major applications are in the area of Pharmaceuticals, food, research, manufacturing, forensics, and bio-monitoring of pollutants.

Abstract:
Antibiotic-resistant bacteria are emerging pathogens whose resistance profiles generate a serious health crisis by holding their impact on human health. Misuse of antibiotics has directed the emergence of microbes immune to presently accessible drugs. Pathogenic bacteria become resistant by employing various mechanisms, such as; antibiotic modification, target site alteration, and biofilm formation, increasing the time they spend in the intracellular environment where antibiotics are unable to succeed at therapeutic levels. Due to this, attempts are being made to develop new alternative nanoantibiotics as a promising approach to treat multidrug resistance disease-causing bacteria. Accordingly, there is considerable contemporary attention to the use of nanoparticles (NPs) as antibacterial agents against different pathogens and as target drug delivery toward specific tissues therefore microbes are eliminated by the biocidal properties of nanoantibiotics. Additionally, the utilization of nanoencapsulation systems can help to beat the issues of, those with toxicity natures, and target drug delivery problems. This review encompasses the antibiotic resistance prevalence, mechanisms, and therefore the use of nanoparticles as antibacterial and drug delivery systems to overcome the antibiotic resistance challenges of bacteria. Overall, this review paper provides a conceptual framework for understanding the complexity of the matter of emergence of antibiotic resistance bacteria even for brand spanking new synthesized antibiotics. Therefore the availability of such knowledge will allow researchers to supply detailed studies about the applications of nanoparticles in the treatment of multidrug-resistant bacteria.

Abstract:
A micellar thin-layer chromatography method for the quantitative determination and validation of coumarin in Meliloti herba and its ethanolic extracts was developed and validated. For achieving good determination, the mobile phase of 5 x 10-4 mol/L Tween-80 in a mixture propanol-2 – water (5:95 v/v) was used. Densitometric determination was carried out at 275 nm. The calibration curve was linear in the range of 0.1-2.5 μg per band. The proposed method is simple, rapid, precise and accurate; replacing hazardous solvents by greener ones correspond to the modern requirements in “Green chemistry” concepts. The obtained data can be used for the routine analysis of coumarin in medical plant and extracts.
