Anti-microbial finishing on Cotton Using Moringa Oleifera
International Journal of Scientific Research in Engineering and Management (, 2020
Moringa Oleifera commonly known as drumstick tree is a fast growing Indian native plant whose parts have many medicinal, antimicrobial properties. Now a days as technology improves consumers are looking for more eco friendly products which won't harm them and the environment. Antimicrobial finishing are done to inhibit the growth of microorganisms when worn close to the skin. The powdered leaves and seeds of the plant along with a concentration of methanol is used to produce the aqueous solution in a soxhlet extractor. This solution is used to finish the terry structured cotton fabric. The method of application is direct method of application along with citric acid as the cross-linking agent. The antimicrobial activity of the finished fabric was assessed by qualitative(AATCC 147) and quantitative methods(AATCC 100) using the testing organisms Staphylococcus Aureus and Klebsiella Pneumoniae. The finished fabric along with Moringa seeds aqueous solution showed antimicrobial activity of 99.99% against Staphylococcus aureus and Klebsiella pneumoniae. The anti-microbial finished fabric can be used to develop hygienic products.
Antimicrobial properties of Moringa Stenopetala seed oil
Moringa stenopetala is a multipurpose tree with considerable economic and social potential as it has vital nutritional, industrial, and medicinal applications. The study was aimed to investigate the antimicrobial activities of M. stenopetala seed oil against pathogenic microorganisms. M. Stenopetala seeds were collected from three locations (Damba Gofa, Shelle, and Konso) and extracted using two different solvents (hexane and petroleum ether). Pathogenic microorganisms: bacteria (gram-positive, Staphylococcus aureus, and gram-negative Escherichia coli) and the fungal strains (Trichophyton mentagrophytes and Candida albicans) were used in this study. Standard procedures were followed to determine antimicrobial activities of M. stenopetala extract against pathogenic microorganisms. The result revealed that M. stenopetala seed extract has shown inhibitory activity against T. mentagrophytes fungi at the concentration ≥ 12.5% at all locations and both extraction solvents used. However, the extract did not show any inhibitory activity against tested bacteria and C. albicans fungi. The finding indicated that M. stenopetala seed could be used as an alternative to chemical fungicide to control T. mentagrophytes fungi. Further investigation is needed on the identification of compounds that inhibits the pathogenic microorganism.

Essential oils as the antibacterial substance in textiles are commonly demanded since they are easily found and have additional properties as relaxation therapy. This study aims to receive an antibacterial cloth using eucalyptus oil as a finishing substance gained from the leaves of Melaleuca leucadendra L. from a local industry (Perhutani Gundih, Central Java). The four types of cotton/polyester fabrics were prepared for finishing treatment with the bathing direct application method. They were 100% cotton, 100% polyester, 80%/20% polyester/cotton, and 65%/35% polyester/cotton. FTIR findings proved the existence of the eucalyptus main compound (α-pinene) in those four fabrics. Moreover, the antibacterial tests using S. aureus cultivation showed that only 100% polyester-treated fabric did not obtain antibacterial properties because the diameter of bacterial inhibition was zero millimeters. The other three fabrics potentially have antibacterial properties even if they did not gain a high diameter inhibitor zone.
In Vitro Antimicrobial Activity of Different Solvent Extracts from Moringa stenopetala Leaves
Preventive Nutrition and Food Science, 2019
This study was conducted to investigate the antimicrobial activities of different solvent extracts of Moringa stenopetala (MS) leaves against nine selected pathogenic microorganisms. The disc diffusion method was used to assess antimicrobial activity and determine minimum inhibitory concentrations (MIC). Methanol, and chloroform extracts showed significant inhibitory activity against Klebsiella pneumoniae and Bacillus cereus. The greatest antimicrobial activity, determined by lowest MIC values (62.5 μg/mL), was observed for inhibition of C. albicans by the ethanol extract and Streptococcus pneumoniae by the methanol extract. The MICs of chloroform extract were 125 μg/mL against Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus, Listeria monocytogenes, and B. cereus. Water extract showed the lowest inhibition against these microorganisms, with MIC values of 250 μg/mL. The data presented in this study suggest that MS leaves have great potential in the development of food preservatives and antibiotic drugs.
Antimicrobial activity of herbal treated cotton fabric
The study focused on the development of bacterial resistant cotton fabric using Murraya Koengii (curry leave) and Zingiber Officinale (ginger) oil. It is also intended to produce Eco-friendly antimicrobial cotton fabric and to protect the consumer from microorganism's contamination. Herbal antimicrobial finish has been imparted to the cotton fabric by pad-dry-cure method. Finish was applied in two concentrations (40g/l and 80g/l) on grey cotton fabric. Weight add-on percent of extract on treated cotton fabric was determined to observe the quantity of extract absorbed by the fabric. The antibacterial activity of the finish was assessed quantitatively using AATCC-100 test method. Qualitative analysis is carried out to measure the antimicrobial activity against Gram-positive (S. aureus, B. subtilis, B. pumilus) and Gram-negative (Pseudo, Candida, E. coli) bacteria.

In this study, the efficiency of Moringa stenopetala seed extract was compared with alum and M. stenopetala alum hybrid coagulant to remove Direct Red 23 azo dye from textile wastewater. The effects of parameters such as pH, coagulant dose, type of salt used for the extraction of coagulant and initial dye concentration on dye removal efficiency were investigated. Moreover, the existing functional groups on the structure of M. stenopetala coagulant (MSC) were determined by Fourier transform infrared spectroscopy, and the morphology of sludge produced byMSC, alum, and hybrid coagulant was characterized by scanning electron microscopy. Ninhydrin test was also used to determine the quantity of primary amines in the MSC and Moringa oleifera coagulant (MOC). According to the results, with increasing the coagulant dose and decreasing the initial dye concentration, dye removal efficiency has increased. The maximum dye removal of 98.5, 98.2, and 98.3 % were obtained by using 240, 120, and 80 mg/L MSC, alum and hybrid coagulant at pH 7, respectively. The results also showed MSC was much more effective than MOC for dye removal. The volume of sludge produced by MSC was one fourth and half of those produced by alum and hybrid coagulant, respectively. Based on the results, hybrid coagulant was the most efficient coagulant for direct dye removal from colored wastewater.

Moring oleifera seed oil was extracted by adding hexane to the seed powder in an electro-thermal soxhlet and evaporating the hexane to produce the 100% seed oil. Different concentrations (75%, 50%, and 25%) of the oil were prepared by aseptically dissolving the measured amount of oil into appropriate volume of Dimethyl Sulfur Oxide (DMSO) on volume by volume (v/v) basis. About 0.3mls of the seed oil extract of the varying concentrations were added to four agar wells and to the fifth well, gentamycin was added as a positive control. The agar plates were then incubated at 350C ± 20C for 24 hours. Effect of the Moring oil extract was assessed by measuring the zones of inhibition to the nearest millimeter, and then compared with the standard gentamycin. The results showed that the 100% seed oil is 78% as effective as the gentamycin against E. coli. It is concluded that the oil can be used as mild antimicrobial agent as skin ointment, hand spray, and sanitizers. It is also recommended that the shelf life of the oil be investigated as well as its action against other common microbes. Keywords: M. oleifera, Seed Oil, Antimicrobial Action, E. coli.

Moringa oleifera (M. oleifera) is a fast-growing, drought-resistant plant found throughout tropical and subtropical regions. A previous study found dry M. oleifera leaf powder to be similarly efficacious to non-medicated soap when used as a hand-wash, even without the use of water. These characteristics suggest that M. oleifera could serve as a potential hand-washing product in water and resource-limited contexts, such as humanitarian and emergency settings. The purpose of this study was to assess the efficacy of minimally processed M. oleifera sourced locally in Ghana as a hand-washing and antimicrobial product by assessing whether: (1) different preparations of M. oleifera have antibacterial properties against potential diarrheal pathogens through set-up of die-off studies; (2) M. oleifera is an effective hand-washing product by conducting an in-vivo trial with healthy volunteers; and (3) M. oleifera has antimicrobial properties in potentially reusable aqueous solutions, such as r...
