“…Furthermore, green tea spoil, pomegranate peels and potatoes peels are contain polyphenols, lignin, cellulose and hemicellulose compounds which contain effective groups that have the ability to adsorb salts ions on its surfaces and the presence of these residues in the nanosize increases its ability to reduce the concentration of salts to more than 99%. The values for polyphenols are 6.50, 5.30 and 2.92% for green tea spoil, pomegranate peels and potatoes peels, respectively, this agree with Mirdehghan and Rahemi (2007), Yang et al, (2008) and Javed et al, (2019).The adsorption improves at neutral pH, most likely due to the deprotonation of active sites that allows a better electrostatic interaction with ions, also, the decrease in the associated ions of sodium chloride in the solution enhances the binding of sodium with the adsorbents so the EC value was decreased according to Kim et al, (2017).…”

The leather industry has a high economic return, but also has harmful effects on society and the environment. One of the most important of these harmful effects is the problem of salinity of water bodies, soil and groundwater. The main objective of the research is to improve the quality of industrial effluent for safe use in agricultural purposes. Green tea (GT), pomegranate peels (PP) and potato peels (Po) were washed with hot distilled water at 85°C several times until its color fades and dried in oven at 105°C and then burned at 400°C, the dried wastes were chemically activated with 1.0 M sulphuric acid for three hours and washed several times with distilled water and dried again. The obtained carbon was ground to very fine powder and characterization by transmission electron microscopy. Nanoparticles size of green tea spoil carbon(GTCn), pomegranate peels carbon (PPCn) and potato peels carbon (PoCn) ranged between 1-50 nm. The result indicated that the effect of green tea spoil carbon nanoparticles at three layers (GTCn3) in addition to potato peels carbon nanoparticles at one layer (PoCn) on removal of salinity from tannery effluent was 99.85% and the parameters of EC, TDS, soluble cations and anions were less than permissible limits for discharge into water bodies. The agricultural residues carbon nanoparticles adsorb the hateful odor, remove yellow color and remove the turbidity.

Potato peels (PPs) are generally considered as agriculture waste. The United States alone generates over one million tons of PPs a year. However, PPs contain valuable phenolic compounds with antioxidant activities. In this study, we evaluated the efficiency of ultrasound-assisted extraction techniques in recovering antioxidants from PPs. These techniques included a direct ultrasound-assisted extraction (DUAE), an indirect ultrasound-assisted extraction (IUAE), and a conventional shaking extraction (CSE). Results of this study showed that DUAE was more effective in extracting phenolic compounds than IUAE and CSE. We also evaluated the factors affecting the yield of total phenolic compounds (TPC) in DUAE, including the temperature, time, acoustic power, ratio of solvent to solids, and size of PPs particles. TPC yield of DUAE was higher, and the extraction rate was faster than IUAE and CSE. Furthermore, TPC yield was strongly correlated to the temperature of the mixture of PPs suspension. SEM images revealed that the irradiation of ultrasound energy from DUAE caused micro-fractures and the opening of PPs cells. The extract obtained from DUAE was found to have antioxidant activity comparable to commercial synthetic antioxidants. Results of this preliminary study suggest that DUAE has the potential to transform PPs from agricultural waste to a valuable ingredient. A future systematic research study is proposed to advance the knowledge of the impact of processing parameters in the kinetics of phenolic compounds extraction from potato peels using various extraction methods.

“…In case of B. licheniformis J1 potato peel was act as biostimulator to increase the petroleum oil degradation potential (Jyoti and Rajesh 2018). According to Javed et al (2019) potato peel is an economy booster for developing countries because it is inexpensive waste of food processing industry and can support many of the industries viz. backing industry, biogas production industry, lactic acid production industry, enzyme production industry, bio-fertilizer industry, bio-fuels industry, bio-sorbent industry, pharmaceutical industry and biosurfactant production industry.…”

Background Commercialization of biosurfactant production is a big challenge due to high production cost. Biosurfactant production can be made economic by using low cost agro-industrial wastes or byproducts as media supplement. It also solves the problem of environmental pollution through waste management. In the present study attempt was made to produce biosurfactant from Sphingobacterium thalpophilum DP9 using various agro-industrial wastes or byproducts at optimum fermentation conditions evaluated by traditional and statistical methods. Partial characterization of biosurfactant was also carried out through qualitative chromatographic techniques; quantitative spectroscopic method and functional group identification by Fourier transform infrared spectroscopy. Results One factor at a time optimization experimentation showed highest emulsification in media supplemented with potato peel powder (43.12 ± 3.41%), urea (46.00 ± 3.09%), pH 7 (41.74 ± 1.15%) at 40% aeration (47.41 ± 1.62%). 1% Inoculum (O.D.600=1.00) size favored highest emulsification (26.39 ± 1.60%). Plackett-Burman design experimentation showed carbon source (potato peel powder), nitrogen source (urea) and temperature significantly affect on biosurfactant production. Response surface experimentation by central composite design showed interaction between nitrogen source and temperature significantly influenced on biosurfactant production. Validation of model was showed increase in emulsification from 43.62 ± 2.55% to 86.11 ± 3.47% on fourth day of incubation. Partial characterization showed biosurfactant contains 439.58 ± 0.0129 µg/ml carbohydrate and 507.41 ± 0.0064 µg/ml of protein. Lipid was absent in it. Fourier transform infrared spectroscopy chromatogram showed peaks at 1652.17 cm− 1, 1541.01 cm− 1, 1463.71 cm− 1 and 722.32 cm− 1 which indicated presence of peptide bond, peptide moiety, carbohydrate protons and primary as well as secondary amines. Conclusion Potato peel powder, urea and temperature have significant influence on biosurfactant production from Sphingobacterium thalpophilum DP9. When potato peel powder and urea supplied at optimum level, biosurfactant production was increased by two fold. Biosurfactant produced by S. thalpophilum DP9 was belongs to glycoprotein class and as per our best knowledge, this is the first report on glycoprotein biosurfactant produced from Sphingobacterium genus.
