Araceli Veronica F. N. Ribeiro, André Romero da Silva, Tiago Pereira da Cunha, Rowenna Tonani L. dos Santos, Jairo Pinto de Oliveira, Evaldo Vitor Pereira, Marcus Vinicius V. J. Licinio, Madson de Godoi Pereira, Arnaud Victor dos Santos, Joselito Nardy Ribeiro
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.712147
Abstract:
A method for adsorption involving banana peel (BP) was studied to remove the pollutant acetylsalicylic acid (ASA) in aqueous medium. The results show that bioadsorbent has satisfactory maximum adsorption capacity (2.29 mg/g) for removing this analgesic and anti-inflammatory drug in aqueous solution (pH 7.0) using the Langmuir mathematical model. The tested concentrations of this pollutant were higher than the levels commonly found in the aquatic environment. This and other results suggest the BP as an alternative to ASA removal in water contaminated with pharmaceuticals pollutants.

Abstract: Banana industry played important roles in Chinese economics. Banana production was always affected heavily by typhoon. Selecting new cultivars with high strength was the basic way to resolve this problem. If the selecting work was performed at mature stage, it will need large area and much labor. If this work can be done at seedling stage, this process will be simplified significantly. We found that banana plants that had high strength at seedling stage always had high strength at mature stage. The physical strength of seedling pseudostem was closely related with pseudostem diameter, lignin content and the expression of 4-coumarate:CoA ligase gene Mu4CL15. Those seedlings whose pseudostem had bigger diameter, more lignin content and higher expression of Mu4CL15 always had higher strength to resist lodging. Through screening plants whose pseudostem had bigger diameter, more lignin content and higher expression of Mu4CL15, plants with high-strength pseudostem can be selected. Using this method, thousands of seedlings can be identified in short time. This process does not need large area and much labor. If this method was applied, the process of breeding new cultivars of banana with high resistance to lodging will be accelerated.

Abstract:

Excess weight and obesity are serious public health problems, which should be addressed through encouraging the consumption of foods with high amount of low digestible carbohydrates. The objective of this study was to put together spaghetti that blends unripe banana whole flour (UBWF) and durum wheat of different levels and to evaluate their chemical composition, starch digestibility and sensory characteristics. Spaghetti with 15%, 30%, and 45% of UBWF and a control spaghetti (100% durum wheat flour) were put together. The protein content decreased (10.42% to 7.74%) as the UBWF level was increased in the composite, while the amount of ash (0.87% to 1.54%) and total starch (70.24% to 73.71%) increased. Spaghetti with 15% and 45% of UBWF had similar available starch content. The addition of UBWF increased the resistant starch content from 1.98% to 10.91%, and consequently the indigestible starch fraction (14.00% to 27.29%). Spaghetti with 30% of UBWF had good consumer acceptability and was ranked higher than the control sample.

Abstract: Plasma lipoprotein(a) (Lp(a)) is known to be a strong independent risk factor for ischemic heart disease. However, it is not easily modulated by drugs that are presently available. Lp(a) is not present in many experimental animals except for Old World monkeys. In this study, we examined whether cynomolgus monkeys are useful model for research of human plasma Lp(a), and observed that plasma Lp(a) in cynomolgus monkeys varied as much as humans. As a result of 4 day-fasting in cynomolgus monkeys, the plasma Lp(a) level decreased in a monkey with originally high Lp(a) level. The Lp(a) level continued to decrease even 3 days after banana feeding, but returned to the original level 3 days after monkey chow feeding. On the other hand, in a monkey with low Lp(a) level, fasting had no effect on the Lp(a) level. However, in the third monkey having originally high Lp(a) level, the Lp(a) was not affected by decreasing the amount of monkey chow feeding by 50%. In summary, we found that cynomolgus monkeys may be an useful model for studying the effects of food on plasma Lp(a) in place of humans, and that high Lp(a) level may be controllable by strict diet regulation.

Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.515138
Abstract: Raw Banana Stalk (RBS), Acid Activated Banana Stalk (AABS) and Base Activated Banana Stalk (BABS) prepared from banana stalk were used as biosorbents to remove Lead(II) from aqueous solution. The biosorbents were characterised using proximate analysis and Fourier Transform Infrared (FTIR) spectroscopy. Pb(II) of 1000 mg/L concentration was prepared from Pb(NO3)2 salt and other concentrations were obtained from this stock through serial dilution. Effects of adsorbent dose, temperature, initial metal concentration, contact time and pH on the percentage Pb(II) removal were evaluated. The Pb(II) concentrations in the solutions were analysed using Atomic Absorption Spectrophotometer. Kinetic, isotherm and thermodynamic parameters were determined. FTIR spectroscopy showed that RBS, AABS and BABS are rich in carboxyl, hydroxyl and phenolic functional groups. At an equilibrium time of 180 minutes, the percentage Pb(II) removal was 63.97%, 96.13% and 66.90% for RBS, AABS and BABS, respectively. Pseudo-second order kinetics best described the process with R2 (0.95, 0.98, 0.97) for RBS, AABS and BABS, respectively. Langmuir isotherm (AABS) has the maximum adsorption capacity (qmax) of 13.53 mg/g and R2 (0.99). Thermodynamic parameters obtained were G0 (?18.75 kJ/mol), H0 (12.63 kJ/mol), S0 (0.05 kJ/mol·K) and Ea (4.37 kJ/mol). Banana stalk has viable characteristics for preparing biosorbents. Acid activated banana biosorbent is more efficient for removal of lead ions from its aqueous solution.

Abstract: The composition of major nutrients, i.e. nitrogen, phosphorus and potassium (NPK), is a critical factor in banana cultivation and also influences crop yield. This study was aimed to analyze the concentrations of NPK in different banana growing locations of coastal areas of Sindh, Pakistan. A total of 15 composite soil samples at the depth of 0 - 15 and 15 - 30 cm and the same number of banana leaves were collected. The samples were analyzed for the concentration of N, P, K, Ca, Mg, Zn, Mn and Cl concentrations. Results showed that the surface and sub-surface soils of coastal areas were heavy in texture, non-saline, medium alkaline and moderately calcareous in nature. Medium to adequate in Organic Matter (OM), medium in total nitrogen, medium to optimum in available phosphorus, medium to high in exchangeable potassium and deficient in available zinc at both tested depths. The analysis of soluble anions indicated that the carbonates were absent and that chlorides were dominant as compared with bicarbonates. Nitrogen and zinc concentrations of banana leaves were below the critical level, whereas P, K, Mn and chloride ion concentration were above the critical levels. In addition, the relative percentages for K, Ca and Mg were 57.72 to 61.72, 19.05 to 21.00 and 17.70 to 20.00 respectively.

Abstract: The erosion of drains is a major limitation of the quality, the increasing of banana production and the environmental protection of industrial banana in Côte d'Ivoire. It leads inundations, death of banana trees and significant loss of production. Thence, the construction and the maintenance of drain costs too much and causes injure, snake bite, physical traumatisms, many diseases, … These events compromise the sustainable production of banana by reducing seriously worker’s the activities and finally increase the cost of production. The aim of the present work is to contribute to the sustainable development and human capacity building in the third world nations as far as banana production is concerned. The methods used so far to address this phenomenon proved inefficient. The technology innovation in this area has been to grow grass on the outer edges of the channels drained water. This resulted in a systematic reduction of erosion. Better still, it helped fertilize the soil, reduce the deportations of fertilizer and improve the quality of landscape of the plantations. Stenotaphrum secondatum is the best vegetable specie adapted to the biological control against water erosion of drains.

Abstract: Fruit wastes which are perishable pose a big problem to pollution monitoring agencies; however these problems can be reduced by utilizing the high value compounds present in the food waste. Banana peels contain a reasonable number of antioxidant compounds such as gallocatechin and dopamine. This paper investigates the anti-oxidant potential of two different varieties of Banana peels (Dwarf cavandish and Musa omini). The peels were extracted with two different solvents (Methanol and Ethanol) using the soxhlet extractor. The results show that ethanolic extracts have higher phenolics and flavonoid contents (336.83 - 383.83 mgGAE/100g, 242.83 - 252.82 mgRutin/100g) compared to the methanolic extracts of the same banana varieties (299.42 - 344 mgGAE/100g, 240.77 - 241.23 mgRutin/100g). However methanolic extracts exhibit higher DPPH Antioxidants Activity (30.82% - 51.66%) compared to ethanolic extracts (25.44% - 30.27%). This implies that antioxidative compounds other than phenolics and flavonoids were also involved in inhibiting the DPPH Radicals. It was also observed that at any concentration between 0.5 - 2.5 mg, ethanol extracts of both dwarf cavandish and musa omini had higher reducing power than the other two varieties.

Abstract: The banana is a food of great importance and it is consumed in almost the entire world. However, its harvest generates large quantities of mostly lignocellulosic waste, which can be used for the production of biofuels such as bioethanol. In this work, the potential for bioethanol production from agro-industrial plantain crop residues was evaluated with different operating conditions. A 24?experimental design was used, having as study variables: time of hydrolysis, pH of hydrolysis, concentration time, and fermentation time. The samples used were scraps consisting of a mixture of stems, leaves, and banana peels. The bioethanol obtained was characterized by physicochemical properties such as density, refractive index, and FTIR. As a result, it was obtained that the volume of bioethanol represented higher yields; using NaOH as a hydrolyzing agent, with hydrolysis time of 30 minutes, high fermentation time, and low concentrations. The chemical characterization of banana agro-industrial waste indicated that, the raw material could be considered as a potential source for bioethanol production, since it has a high content of cellulose.

Abstract: We present draft genome sequences for three strains of Xanthomonas species, each of which was associated with banana plants ( Musa species) but is not closely related to the previously sequenced banana-pathogen Xanthomonas campestris pathovar musacearum. Strain NCPPB4393 had been deposited as Xanthomonas campestris pathovar musacearum but in fact falls within the species Xanthomonas sacchari. Strain NCPPB1132 is more distantly related to Xanthomonas sacchari whilst strain NCPPB 1131 grouped in a distinct species-level clade related to X. sacchari, along with strains from ginger, rice, cotton and sugarcane. These three newly sequenced strains share many genomic features with the previously sequenced Xanthomonas albilineans, for example possessing an unsual metE allele and lacking the Hrp type III secretion system. However, they are distinct from Xanthomonas albilineans in many respects, for example showing little evidence of genome reduction. They also lack the SPI-1 type III secretion system found in Xanthomonas albilineans. Unlike X. albilineans, all three strains possess a gum gene cluster. The data reported here provide the first genome-wide survey of non-Hrp Xanthomonas species other than Xanthomonas albilineans, which is an atypical member of this group. We hope that the availability of complete sequence data for this group of organisms is the first step towards understanding their interactions with plants and identifying potential virulence factors.
