Adsorption Study of Soluos Dumpsite Leachate Treatment Using Musa sapientum Peels as Biosorbent

Dumpsite leachate has the potential to pollute ground and surface water as well as vegetation within the vicinity of the dumpsite. Its treatment therefore needs adequate attention. The aim of this work is to study the adsorption of Soluos dumpsite leachate treatment using Musa sapientum peel as biosorbent with a view of establishing the adsorption isotherm model. Musa sapientum peels sourced from Ayetoro market in Epe area of Lagos State, Nigeria were used to prepare the adsorbent. Batch adsorption was carried out with various dosage of the prepared absorbent in leachate collected from Soluos dumpsite in Lagos. The adsorption data obtained were fitted into Linear, Freundlich, Langmuir, Temkin and Hasley isotherm models. The results showed that the concentration of total dissolved solids (TDS) in the dumpsite leachate decreased as the adsorbent dosage increased. At adsorbent dosage of 10 g/L, the concentration of TDS in the leachate was 485.7 mg/L which was less than the 500 mg/L stipulated by National Environmental Standard and Regulatory Agency (NAESRA) for the discharge of wastewater. The coefficient of determination (R2) values for Linear, Freundlich and Hasley, Langmuir and Temkin isotherm models were 0.9944, 0.9936, 0.8562 and 0.9723 respectively. Linear isotherm model was jettisoned because the plot did not pass through the origin and Freundlich isotherm model was ignored as a result of N value which was less than unity hence Hasley isotherm model was adopted in this work. A good correlation existed between the experimental and predicted values, having a R2 value of 0.9965 which further validated the Hasley isotherm model as the best adsorption model for the treatment of Soluos dumpsite leachate using Musa sapientum peel as biosorbent. It was concluded that Musa sapientum peel as biosorbent can be used for treatment of Soluos dumpsite leachate.

Comparative Study on Treatment using Water-based Extract of Fresh and Dry Unripe Banana Peels with Conventional Antibiotics on UTI

Almost every part of a banana plant has use in medicine. Increased bacterial resistance to the conventional antibiotics has led to research into the development of alternative treatments to conventional antibiotics. This study focuses on the antimicrobial properties of banana peels against selected isolates from Urinary Tract Infection sample. The isolates from cultures further analysed with agarose gel electrophoresis for the presence of 16SrRNA and Phylogenetic analysis revealed Staphylococcus sciuri strain, a coagulase‐negative species, Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae and Proteus mirabilis. Fresh unripe and dry unripe were used to determine the antimicrobial activities. A measure of 150grams of both fresh unripe and dry unripe was extracted with 100ml of water solvent (sterile) respectively for about 2days. The solvent extracts were concentrated separately under reduced pressure, 10g of each concentrated solvent extracts were dissolved in 5ml of sterile distilled water and used for antimicrobial assay using agar well diffusion method. The phytochemical analysis of fresh unripe and dry unripe revealed that alkaloid, flavonoid, cardiac glycosids,and phenols were present.. Musa sapientum L peels showed some effect on Escherichia coli, Enterococcusfaecalis, Staphylococcus sciuri, Klebsiellapneumoniae and Proteus mirabilisat 80% concentrations for water. Dry unripe has advantage over fresh unripe banana peels. The peels of Musa sapientum exhibited some inhibitory activity on these selected UTIs isolates, which could be attributed to the presence of certain secondary metabolites. Finally, when compared the peels extracts against the standard antibiotics drugs as the control, the water solvent extract were less effective.

Kinetic modelling of dumpsite leachate treatment using Musa sapientum peels as bio-sorbent

Kinetics models are very vital to dumpsite operators and planners as they provide relevant information for effective treatment of leachates. The aim of this work is to model the kinetic process of treatment of Lagos dumpsite leachate using Musa sapientum peels as bio-sorbent with a view of establishing the kinetic parameters of the treatment process. Musa sapientum peels which were collected from Ayetoro market in Epe Local Government area of Lagos State were used to prepare the bio-sorbent. Kinetic process was carried out using 1 g of the prepared bio-sorbent in 100 ml Lagos dumpsite leachate in different conical flasks and at various contacting time. The kinetic data obtained were fitted to different kinetics models. The kinetics models tested were Fractional power model, Lagregren pseudo first – order model, Pseudo second – order model, Kuo – Lotse kinetic model, Blanchard kinetic model and Elovich kinetic model. Other kinetics models considered were Sobkowsk – Czerwi kinetic model, Intraparticle diffusion (IPD) model, Behnajady – Modirshahla – Ghanbery (BMG) model and Diffusion – Chemisorption model. Coefficient of determination (R2) values and the expected nature of the plots of the models were used to screen the tested models. The results revealed that the Pseudo second – order kinetic model has the best R2 value of 0.99996 and the graph followed the expected nature of the plot hence it was adopted in this work. It was concluded that Pseudo second – order kinetic model can be used to navigate the treatment process of Lagos dumpsite using Musa sapientum peels as bio-sorbent.

Utilización de la fibra de banana (musa sapientum) proveniente de los pseudotallos para la elaboración de papel y el aprovechamiento de residuos agrícolas

Ecuador es uno de los mayores productores y exportadores de banano a nivel mundial, dejando residuos de tipo orgánico, plásticos y cartones no reutilizados. La presente revisión bibliográfica analizó el aprovechamiento de los residuos de la Banana (Musa sapientum), por el potencial que tiene la fibra de esta fruta extraída principalmente de los pseudotallos, para la elaboración de papel. La investigación detalla que la obtención de la fibra comienza con la separación de lignina de la celulosa por medio de un digestor, seguido por las etapas de lavado, blanqueado, golpeado, prensado y secado. Su composición química de bajo contenido de lignina y alto contenido de alfa celulosa permite su reutilización para la elaboración de papel de buena calidad, biodegradable, económico y no tóxico. El análisis de la información y los datos recopilados mostraría que posee propiedades mecánicas como absorción, densidad, flexibilidad y resistencia, comparables con la fibra maderera. El proceso investigado, haría más eficiente y eficaz la cadena de producción del banano al reducir las pérdidas, con posibilidades de expandirse a un mundo globalizado que tiende a procesos más ecológicos. Debido a ello, a futuro se espera poner en práctica la fabricación de este tipo de papel.

The Ethanol Extract of Musa sapientum Linn. Peel Inhibits Melanogenesis through AKT Signaling Pathway

Hyperpigmentation caused by melanin overproduction can be induced by UV radiation. The quest for effective depigmenting agents continues because many anti-melanin agents have restricted use and/or produce side-effects. The present study was aimed to investigate the inhibitory activity of Musa sapientum Linn. (AA group) peel ethanol extracts (MPE) on α-melanocyte stimulating hormone (α-MSH)-induced melanin production. In addition, the molecular mechanism related to this process was examined in B16F10 mouse melanoma cells. The results indicated that MPE remarkably inhibited melanogenesis in α-MSH-stimulated B16F10 cells. Microphthalmia-associated transcription factor (MITF) and tyrosinase expressions were suppressed by MPE in a concentration-dependent manner. In addition, MPE significantly decreased the expression of melanosome transfer protein markers (Rab27a and Pmel17) in a dose-dependent manner. This study found that the elevated phosphorylation of AKT in the B16F10 cells was diminished by MPE treatment. Furthermore, microtubule-associated protein 1 light chain 3 (LC3)-II and p62 (autophagy markers) were affected after the B16F10 cells were treated with MPE. This study demonstrated that MPE might be an effective agent for anti-melanogenesis through the AKT pathway, subsequently diminishing MITF expression and tyrosinase enzyme family production. The findings indicated that MPE could potentially serve as a depigmenting agent in cosmeceuticals.

Gas Chromatography –Flame Ionization Detector, Phytochemical and Quality Control of Unripe Musa Sapientumthrough UV-Vis Spectrophotometric analysis

Musa sapientum(banana) is widely consumed for its health benefits. Its pulp, peel, leaves, bark as well as whole fruit is used in reducing the risk of chronic diseases of clinical interests. This study aims to find out whether or not there are any distinctive phytochemical constituents present in unripe Musa sapientum peel, pulp and whole fruit hydromethanolic extract using GC-FID techniques and to demonstrate the importance of spectral data in contribution to quality control of its medicinal properties. The UV-VIS profile showed different peaks ranging from 200-900 nm with different absorption respectively. UV-VIS profile showed 9 peaks with three distinct peaks at 240 nm, 400 nm, and 700 nm for both pulp and its peel while 22 peaks with four at 220 nm, 290 nm, 550 nm and 600nm for whole fruit. GC-FID analysis provided characteristic peaks determining the presence and concentration of phytochemical compounds in peel, pulp and whole fruit. Three major phytoconstituents were found almost exclusively in peel, including, Isoflavones, lunamarine and sapogenin while proanthocyanidin and resveratrol were exclusively in its pulp. Spartein, phytates, tannins and isoflavones were absent in whole fruit. The concentration of flavone was minimal. In conclusion, the study justifies the nutritional and medicinal properties of the plant and also represents an additional support to the quality control of their fruit drugs. The presence of the distinctive phytochemicals may be mechanistic link for the specific-efficacy of their physio-pharmacologic and therapeutic activities. Ingested together, these study data suggests that peel, pulp or whole fruit supplementation may be a potential alternative to conventional treatment for various types of infirmities and may confer other potential industrial, nutritional and medicinal advantages.
