OBJECTIVE To develop a simple rapid procedure for bioreduction of silver nanoparticles (AgNPs) using aqueous leaves extracts of Catharanthus roseus (C. roseus). METHODS Characterization were determined by using UV-Vis spectrophotometry, scanning electron microscopy (SEM), energy dispersive X-ray and X-ray diffraction. RESULTS SEM showed the formation of(More)
Lactic cultures were screened for their ability to accumulate γ-aminobutyric acid (GABA) in the culture medium. Lactobacillus bulgaricus CFR 2028 produced the highest yields of GABA (22.7 mM) from the substrate monosodium glutamate (MSG). Instrumental characterization by high-performance liquid chromatography and structural characterization by mass(More)
Biosurfactants are surface-active compounds derived from varied microbial sources including bacteria and fungi. They are secreted extracellularly and have a wide range of exciting properties for bioremediation purposes. They also have vast applications in the food and medicine industry. With an objective of isolating microorganisms for enhanced oil recovery(More)
Phenol and its derivatives are considered among the most hazardous organic pollutants from industrial wastewater and they are toxic even at low concentrations. Besides the existence of phenol in natural water source it can lead to the formation of other toxic substituted compounds. So this has led to growing concern on setting up of rigid limits on the(More)
Phase diagrams and the compositions of coexisting phases of poly(ethylene glycol) (PEG) 6000 + sodium succinate + water system have been determined experimentally at 298.15, 308.15, and 318.15 K. The effects of temperature on the binodal curve and tie lines have been studied. The binodal curves were successfully fitted to a nonlinear equation relating the(More)
