“…The peel of the fruit contains various antioxidant compounds, such as gallocatechin (Someya et al 2002) and dopamine (Kanazawa and Sakakibara 2000). A few applications of banana peels discussed in the literature include (1) exploitation for their medicinal properties (Parmar and Kar 2008), (2) in ethanol fermentation (Tewari et al 1986), (3) application as a substrate for generating fungal biomass (Essien et al 2005), (4) use in the production of laccase (Osma et al 2007) and (5) utilization as a biosorbent for heavy metal removal (Annadurai et al 2003). On the basis of the available literature, we hypothesized that banana peels that are inherently rich in polymers such as lignin, hemicellulose and pectins (Happi Emaga et al 2007) could be used in the synthesis of silver nanoparticles.…”

Biosynthesis of metallic silver nanoparticles has now become an alternative to physical and chemical approaches. In the present study, silver nanoparticles (AgNPs) were synthesized from Cavendish banana peel extract (CBPE) and characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Atomic force microscopy (AFM), Field emission scanning electronic microscope (FESEM), Dynamic light scattering (DLS) and zeta potential (ZP). The AgNPs formation was confirmed by UV-visible spectroscopy through color conversion due to surface plasma resonance band at 430 nm. The effect of pH on nanoparticle synthesis was determined by adjusting the various pH of the reaction mixtures. The crystalline nature of nanoparticles was confirmed from the XRD pattern, and the grain size was found to be around 34 nm. To identify the compounds responsible for the bioreduction of Ag ? ion and the stabilization of AgNPs produced, the functional group present in Cavendish banana peel extract was investigated using FTIR. AFM has proved to be very helpful in determining morphological features and the diameter of AgNPs in the range of 23-30 nm was confirmed by FESEM. DLS studies revealed that the average size of AgNPs was found to be around 297 nm. Zeta potential value for AgNPs obtained was -11 mV indicating the moderate stability of synthesized nanoparticles. The antibacterial activity of the nanoparticles was studied against Gram-positive and Gram-negative bacteria. Biosynthesized AgNPs showed a strong DPPH radical and ABTS scavengers compared to the aqueous peel extract of Cavendish banana.

This study aims to determine the most effective compound used to hydrolyze soy husk waste to produce reducing sugar as raw material for bioethanol fermentation. The study was conducted at the Laboratory of Bioprocess PPPTMGB "LEMIGAS" in April-September 2015. The method used is experiment using a randomized block design consisting of two factors. The first factor is the type of compounds used in the process of hydrolysis, namely H2SO4, HCl, NaOH, and NH3. The second factor is the concentration of hydrolyze compound 0.2%, 0.4%. 0.6%, 0.8%, and 1% (v/v) and every treatment repeated 4 times. Parameters measured were content of reduced sugar hydrolysis product, and secondary data that content of cellulose and hemicellulose also the density of ethanol. Concentration of reducing sugar from hydrolysis of soybean husk is analyzed by two-way ANOVA test. ANOVA analysis result indicate that the best hydrolysis compounds in hydrolizing soybean husk is HCl with the optimum concentration is 0,4%. And there are interactions between treatment of compound used to hydrolyze as well as concentration on reducing sugar concentration (mg/mL) as product from soybean husk waste hydrolysis. Post-hoc test showed that HCl 0,4% produce the highest concentration of reducing sugar at 31.23 mg/mL.

“…As raw materials, banana pulp is rich in beneficial bioactive compounds, used in the development of phytomedicine and allopathic medicines. Other reports described the usage of banana peel extracted with ethanol (Tewari, Marwaha & Rupal, ) and methane (Bardiya & Somayaji, ; Gunaseelan, ), administrated in diets for livestock (Onwuka, Adetiloye & Afolami, ), or as adsorbents in water purification (Annadurai, Juang & Lee ). The administration of hot‐water banana peel ( Musa acuminate ) extract into diets showed enhanced resistance to pathogen infection, growth performance and immunological responses of M. rosenbergii (Rattanavichai, Chen, Chang & Cheng, ; Rattanavichai & Cheng, ).…”

Musa acuminate peel extract as an immunostimulant, administrated in the diets of Macrobrachium rosenbergii, and an assessment of a simplified process to develop low‐cost feed additives are conducted in this study. The products obtained serially, during the processes of hot‐water banana peel extraction, were administrated in the diets of M. rosenbergii, including dried banana peel powder (DBP) at 8 g/kg, hot‐water‐treated banana peel (HBP) at 8 g/kg and hot‐water extract of banana peel (BPE) at 2 g/kg during the 32 days of the feeding trial. Total haemocyte count, different haemocyte count, respiratory bursts; and activity of superoxide dismutase, glutathione peroxidase, phenoloxidase and transglutaminase, as well as an accelerated haemolymph clotting time, significantly increased in M. rosenbergii fed with diets containing HBP and BPE, 32 days post‐feeding. Furthermore, the phagocytic activity and clearance efficiency of prawns against Lactococcus garvieae infection increased significantly. The respective relative survival percentages of prawns fed with HBP, and BPE containing diets after 32 days of feeding trial were 29.2% and 41.7% against L. garvieae infection for 144 hours, and 50%, and 50% against hypothermal stress for 96 hours of exposure. We may therefore conclude that HBP, obtained from a simplified procedure, without centrifugation and lyophilization, may strategically promote tolerance to hypothermal stress, and enhance immunity and resistance to L. garvieae infection.
