Piliostigma Thonningii

Iron nanoparticles have gained tremendous attention due to their application in magnetic storage media, ferrofluids, biosensors, catalysts, separation processes, environmental remediation and antibacterial activity. In the present paper, iron nanoparticles were synthesized using aqueous flower extract of Piliostigma thonningii, a natural nontoxic herbal infusion. Iron nanoparticles were generated by reaction of ferrous chloride solution with the flower extract. The reductants present in the flower extract acted as reducing and stabilizing agents. UV-vis analysis of the iron nanoparticles showed continuous absorption in the visible range suggesting the iron nanoparticles were amorphous. This was confirmed by X-ray diffraction (XRD) analysis which did not have distinct diffraction peaks. Scanning electron microscopy (SEM) analysis revealed that the synthesized iron nanoparticles were aggregated as irregular clusters with rough surfaces. FT-IR studies showed the functional groups that participated in the bio-reduction process to include a C-H stretch (due to alkane CH3, CH2 or CH), C=O stretch (due to aldehydes), O-H bend (due to tert-alcohol or phenol), C-O stretch (due to aldehydes or phenols) and C-O stretch (due to alcohols) corresponding to absorptions at 2929.00, 1721.53, 1405.19, 1266.31 and 1030.02 cm-1 respectively. The iron nanoparticles showed significant antibacterial activity against Escharichia coli and Staphylococcus aureus suggesting potential antibacterial application.

Iron nanoparticles (FeNP) were synthesized using Acacia nilotica seedless pods extract. The synthesized FeNP were characterized by Fourier transform infrared (FTIR), UV/Vis spectroscopy, dynamic light scattering (DLS), electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD). The XRD pattern confirmed the synthesis of crystalline phase of α-Fe2O3. EDS spectroscopy showed the presence of elemental iron and oxygen, indicating that the nanoparticles are essentially present in oxide form. UV absorption in the range of 450–550 nm confirmed the formation of FeNP. DLS indicated an average FeNP particle size of 229 nm. The synthesized FeNP was tested for adsorption and oxidation degradation of methyl orange (MO) under different conditions and found to be effective in both degradation and adsorption processes. Furthermore, the synthesized FeNP has the potential to terminate the pathogenicity of several human opportunistic pathogens; belongs to gram-negative and gram-positive bacteria and one species of Candida as well.

The study has an objective of isolating and characterizing suspected Streptomycetes with the potential to decompose organic compounds in arable soil. The isolates were grown on a culture media and a total of 61 slopes were inoculated and labeled using the following characterization tests: catalase test, gram staining, oxidase test, motility test, and oxidative-fermentative test. After characterization tests, data generated in the laboratory were analyzed and the study showed that isolates A2 (c, e), B2 (c), C1 (b), C2 (a), D1 (e) and D2 (d) were suspected to be Streptomycetes species. Isolates D1 (d) and D2 (b) were suspected to be Escherichia coli while isolates A1 (a), B2 (a, b) and D1 (a) were suspected to be Bacillus species. Isolates A1 (b), C1 (a), D1 (c), D2 (e) were suspected to be Pseudomonas species. Further identification showed that isolates A2 (d) and B1 (b) could be Enterobacter species while isolates A2 (a, b) were suspected to be Klebsiella species. The study tentatively identified Streptomycetes species; Escherichia coli; Bacillus species; Enterobacter species; Pseudomonas species and Klebsiella species. The suspected Streptomycetes identified were considered as potential organic matter decomposers in arable soil.

Research on the potential of Ashoka (Ixora javanica) flower as a natural food and beverage coloring agent in terms of pH stability during the storage period. This study aims to determine the stability of Asoka flower extract on the effect of pH during the storage period. The time used was 10 days and the variation of pH of  2,3,4,5 and 6, respectively. The results show that Asoka flower extract was stable at pH 2 after a 10-day storage period with degradation presentation of 36.21%, while Ashoka flower extract dyes were unstable at pH 6 after a 10-day storage period with degradation percentage is 78.02%. This proves that the different acidic atmosphere influences the stability of Ashoka flower extract. Keywords : Dyes, stability of Ashoka flowers, degradation

Cattle Market

A pregnant cow of Kuri breed, estimated age of six years old with second calving was transported on land from Maiduguri, Borno state Nigeria. The journey took four days to the Akinyele International Cattle Market. The pregnant cow calved immediately on arrival at the market. A week after calving, the nursing cow was offered for sale and slaughter. The nursing cow and the calf were purchased and put under intensive medical and management care of an experienced cattle stockman in the market. The nursing cow became diarrheic on the second week of arrival at the market. Clinical examination by visual observation revealed projectile watery faeces, stained hindquarter and the pair rectal sterile swab samples were collected. Though the temperature and pulse rate were within the normal range. Standard bacteriological faecal culture of the rectal swab incubated overnight at 370C in selenith F- broth, Nutrient and blood agars at 370C for 24 hours were done, revealing heavy mixed growth of Escherichia coli, Klebsiella species and Bacillus species. Identification of colonies were based on morphology, gram staining, cultural and biochemical characteristics. In-vitro Antibiotic sensitivity testing on discrete colonies of bacteria faeces were done, using agar- Disk diffusion method. The E. coli, Klebsiella and Bacillus species were sensitive to ciprofloxacin® (10μg) and pefloxacin® (30μg). Sulfanol® (sulphadimidin) a broad spectrum antibiotic was administered immediately intramuscularly at 333mg in 3ml per 10kg for four days. Defaecation of the nursing cow stopped for two days after treatment. On the third day of the treatment, the faeces became pasty but the cow died overnight despite the good response to therapy.

AbstractIn majority cities of Pakistan, ground water is the main source of drinking water supply in the taps. Studies from different areas of Pakistan reported the presence of arsenic (As3/5+) and fluoride (F−) in drinking water supplies and can be envisaged as a deep-rooted cause of daily exposure of these in humans. The present study was planned with three way approach, i.e., to assess drinking water quality in Multan city, a highly populated and industrial activity area; synthesis of nano-adsorbent for simultaneous, effective and low-cost removal of fluoride and arsenic and manage waste by utilization of kitchen waste for synthesis of the nano-adsorbent. Out of 30 samples collected, 80% and 73% samples were found exceeding maximum residual limits (MRL) for F− and As3/5+, respectively, while 53% samples had both As3/5+ and F− concentrations greater than MRL. All these water samples were then treated with prepared nano-adsorbent, i.e., iron nanoparticles doped kitchen waste charcoal after evaluating the optimized experimental parameters and application of adsorption, kinetics and thermodynamic models. The nano-adsorbent showed high removal efficacy 81–100% for F− and 13–100% for As3+.
