Preparation and characteristics of biodegradable mulching films based on Fermentation industry Wastes
International Biodeterioration & Biodegradation, 2016Co-Authors: Ma Zefeng, Ma Yubo, Lizhen Qin, Jixiang LiuAbstract:Abstract To solve the serious environmental pollution caused by both Fermentation industry Wastes and traditional plastic mulching film, a novel biodegradable mulching film (BMF), based on the combination of hydrogen peroxide (H2O2) oxidation and polyvinyl alcohol (PVA) polymeric modification technologies, was prepared from citric acid Fermentation Wastes (CAFW). The tensile strength (TS) and elongation at break (%E) of BMF could reach 16.43 MPa and 446.96% respectively at oxidant concentration of 4% (w/v) and CAFW/PVA ratio of 70/30. Meanwhile, the water vapor barrier properties of BMF were improved. In the soil covering test, BMF degradation and increased soil temperatures and moisture were achieved, which lead to effectively improving crops growth, soil microbial community structure and soil enzyme activities. Finally, after 80 days of degradation, the weight loss of BMF reached 72.6%. These results indicated that the degradation performance of BMF could facilitate crops growth in different growing periods.

Innovative Biogas Multi-Stage Biogas Plant and Novel Analytical System
Energy Procedia, 2012Co-Authors: F. Moedinger, F. Ast, M. Ragazzi, P. Foladori, Elena Cristina Rada, R. BinnigAbstract:The here presented applied research and development project is targeted to the development and application of new and improved techniques in plant design, performance analysis and process control. Hereto following the required steps are illustrated and the goals are outlined. The project covers the development of a previously patented anaerobic digestion process, adaption of flow cytometry as an analytical instrument and investigation of innovative ways of disposal of solid Fermentation Wastes. The preliminary experiences with a newly built research plant employing a novel anaerobic biogas digestion technique are discussed. In this paper the first outcomes concerning the construction and operation are discussed. A novel method of disposal of the Fermentation Wastes is also discussed and first results are shown.

Valorization of Escherichia coli waste biomass as a biosorbent for removing reactive dyes from aqueous solutions
Desalination and Water Treatment, 2015Co-Authors: Sok Kim, Sung Wook Won, Chul-woong Cho, Yeoung-sang YunAbstract:AbstractIndustrial waste biomass of Escherichia coli was developed as a biosorbent of Reactive Yellow 2 (RY2). The raw biomass was modified by esterification under acidic conditions to remove the carboxyl groups that could interfere with the binding of RY2 to the biomass. The maximum uptake of the esterified biomass was 335.16 ± 5.81 mg/g, which was 1.5 and 8.3 times higher than those of the raw biomass and ion-exchange resin (Amberjet 4200), respectively. This study can be a step forward to the feasible valorization of microbial Fermentation Wastes as an adsorbent.

Removal of 1-ethyl-3-methylimidazolium cations with bacterial biosorbents from aqueous media.
Journal of hazardous materials, 2012Co-Authors: Sung Wook Won, Sun Beom Choi, Juan Mao, Yeoung-sang YunAbstract:This study aims to determine whether biosorption can be used for the removal of ionic liquids (ILs), especially their cationic parts, from aqueous media. As a model IL, 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc) was used. Five types of bacterial biosorbents were prepared from Fermentation Wastes through chemical modification of the bacterial surface. Screening study was performed to compare the cationic [EMIM] biosorption capacity among the bacterial biosorbents, indicating that the succinated Escherichia coli biomass (SB-E) was the best biosorbent for removing [EMIM] cations. The [EMIM] biosorption performance of SB-E was evaluated in detail through various experiments. The optimal pH range for [EMIM] biosorption was from 7 to 10, and biosorption equilibrium was reached within 10 min. The maximum uptake of SB-E was also estimated to be 72.6 mg/g. Moreover, [EMIM] cations were easily desorbed from [EMIM]-sorbed SB-E by adding acetic acid.
