Traditional medicine using Jasminum leaves to treat oral health problems is expected due to easy access. Furthermore, due to the rising issue of antibiotic resistance, discovering a natural antibiotic that can effectively replace synthetic antibiotics would be valuable as natural antibiotics can cover the benefits, challenges, and future development. This study aims to assess the antimicrobial properties of ethanolic and aqueous extracts of Jasminum sambac L. leaves at the concentration of 50, 150, and 250 mg/ml against E. coli ATCC 25922, P. aeruginosa ATCC 10145, S. aureus ATCC 33591 and B. cereus ATCC 11778, C. albicans ATCC 10231 and A. …

The screening of lanthanide as a critical mineral and used as an anti-amoebic agent is important to identify the safest method and mode of cell death to eliminate this microorganism from the host. In this study, gadolinium ion (Gd3+) that complexed with a short acyclic triethylene glycol (EO3) and in the presence of picric acid (HPic) as counter anion for anti-amoebic activity was explored. The trivalent Gd3+ complexed with EO3 and HPic via one-pot synthesis reaction using a mole ratio of gadolinium nitrate salt, EO3 ligand and HPic in a mole ratio 1:3:4 to produce [Gd(Pic)2 …
Activated Carbon Derived From Rice Husk Biomass Using Pyrolysis-Assisted Tartaric Acid Activation For Removal Of Reactive Orange 16 Dye: Adsorption Modeling Using Response Surface Methodology, Ahmed Saud Abdulhameed, Ruihong Wu, Abdallah Reghioua, Harun M.

In the current work, rice husk (RH) biomass was pyrolyzed using tartaric acid as an activating agent to produce activated carbon (AC). For 60 min, the procedure was run at 700 °C and 5 L/min of nitrogen (N2) flow rate. The study used response surface methodology (RSM) and a 3-level Box-Behnken design (BBD) to optimize the extraction efficiency of rice husk activated carbon (RHAC) in eliminating reactive orange 16 (RO16) dye from an aqueous solution. Different process parameters, such as pH (2–12), RHAC dose (0.04 – 0.14 g), and time (60-240 min), were chosen as part of the …

The extensive use of crystal violet (CV) dyes may cause water pollution. A highly porous and functionalized activated carbon can be used for adsorption of CV dyes. Activated carbon was prepared from oil palm fronds through microwave-assisted pyrolysis and activation with phosphoric acid (H3PO4) for removal of CV dye from wastewater. The physico-chemical characteristics of oil palm fronds activated carbon (OPFAC) was employed by Brunauer-Emmett-Teller (BET) surface area analysis, Fourier transform infrared (FT-IR) analysis, Scanning Electron Methodology-Energy Dispersive X-Ray (SEM-EDX) analysis, thermogravimetric analysis (TGA), and point of zero charges (pHpzc). The adsorption parameters such …

Food poisoning caused by foodborne microorganisms is a significant public health concern. This study aims to investigate the impact of several nutritional and environmental parameters on the growth of Escherichia coli, Bacillus subtilis, Staphylococcus aureus, and Streptococc pyogenes in both model systems and food. The specific impact of temperature, pH, and UV light stress on pathogens.Applying physical stress on microorganisms is a standard method to induce cell inactivation and promote food stability.This study found that the optimal temperature for the growth of these pathogens is between 30°C and 50°C. No growth was observed beyond 50°C, indicating temperature sensitivity; low temperatures …
