This research work investigates the application of KOH impregnated jackfruit leaf powder to remove Nickel from wastewater. The removal characteristics of Nickel from wastewater was investigated under various operating variables like contact time, adsorbent dosage, initial metal concentration, solution pH, temperature and stirring speed. The results showed that the KOH impregnated jackfruit leaf...
Methods. Skin scrapings were taken from outpatients with superficial dermatomycoses and cultured in Sabouraud dextrose agar with cycloheximide. They were then evaluated under a microscope using both the KOH wet mount technique and the new contrast stain. Two investigators read the slides together but were blinded to all other test results. The new contrast stain contains 1% Chicago sky blue 6B ...
Plant lignin is one of the major wall components that greatly contribute to biomass recalcitrance for biofuel production. In this study, total 79 representative Miscanthus germplasms were determined with wide biomass digestibility and diverse monolignol composition. Integrative analyses indicated that three major monolignols (S, G, H) and S/G ratio could account for lignin negative influence on...
BACKGROUND Fatty acids (FAs) are important as raw materials for the biotechnology industry. Existing methods of FAs production are based on chemical methods. In this study potassium hydroxide (KOH)-catalyzed reactions were utilized to hydrolysis Jatropha curcas seed oil. RESULTS The parameters effect of ethanolic KOH concentration, reaction temperature, and reaction time to free fatty acid (F...
The agar diffusion assay was used to examine the effect of pH on the ability of alkaline salts of 3 fatty acids (FA) to inhibit growth of bacteria associated with poultry processing. FA solutions were prepared by dissolving 0.5 M concentrations of caprylic, capric, or lauric acid in separate aliquots of 1.0 M potassium hydroxide (KOH). Citric acid was added to the FA-KOH mixtures to reduce the ...
This research work investigates the efficiency of H3PO4and KOH impregnated jackfruit leaf powder based carbon as adsorbent to remove Ni from wastewater. The removal characteristics of Nickel using both the adsorbents were investigated under various operating variables like contact time, adsorbent dosage, initial metal concentration, solution pH, temperature and stirring speed. The results showe...
Bismuth telluride (Bi2Te3) nano particles were prepared by refluxing method in different conditions such as varying concentration of KOH and reaction timings. X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements have been performed for structural and phase formation studies. The nanoparticles are showing the same structure of bulk except broadening of peak confirmed b...
