论文标题Combined effects of carbon, phosphorus and nitrogen on lipid accumulation of Chlorella vulgaris in mixotrophic culture
作者Chao Li, Yanling Yu**, Dawei Zhang, Jia Liu, Nanqi Ren, Yujie Feng*
期刊名称《Journal of Chemical Technology & Biotechnology》
期卷2016,91(3)
简单介绍Microalgae biodiesel has attracted considerable attention, however, low lipid content has significantly restricted its development. Many research studies have demonstrated that nutrient deficiency is an important factor stimulating lipid accumulation in algal cells. This present study investigated the combined effects of nitrogen, phosphorus, and carbon on algal lipid accumulation by Chlorella vulgaris in mixotrophic culture.
论文标题Effects of extractives on digestibility of cellulose in corn stover with liquid hot water pretreatment
作者Zimu Li, Yanling Yu*, Jiaxing Sun, Dongmei Li, Yudong Huang , Yujie Feng
期刊名称BIORESOURCES
期卷2016, 11(1
简单介绍Many herbaceous lignocelluloses suitable for ethanol production have high extractives contents, such as some straws and corn stover. The high extractives content might affect pretreatment or enzymatic hydrolysis. In this study, extractives were removed from corn stover, and then extractives-free corn stover and ordinary corn stover were respectively pretreated using a liquid hot water (LHW) method and hydrolyzed to evaluate the effect of extractives on cellulose digestibility. Extractives-free corn stover presented higher cellulose digestibility than ordinary corn stover after the same pretreatment conditions. A total of 87.3% of cellulose was digested in extractives-free corn stover, compared to 71.0% in ordinary corn stover, after pretreatment at 200 degrees C for 20 min. It is speculated that some water-soluble extractives could buffer H+ ions from water and acetic acid during LHW pretreatment process, reducing xylan removal. Another reason for these results might be that some extractives could condense on corn stover after LHW pretreatment, which hinders cellulose hydrolysis.
论文标题Microbial community analysis in a combined anaerobic and aerobic digestion system for treatment of cellulosic ethanol production
作者Lili Shan, Yanling Yu, Zebing Zhu, Wei Zhao, Haiman Wang, John J. Ambuchi, Yujie Feng
期刊名称Environmental Science and Pollution Research
期卷2015, 22:1
简单介绍This study investigated the microbial diversity established in a combined system composed of a continuous stirred tank reactor (CSTR), expanded granular sludge bed (EGSB) reactor, and sequencing batch reactor (SBR) for treatment of cellulosic ethanol production wastewater. Excellent wastewater treatment performance was obtained in the combined system, which showed a high chemical oxygen demand removal efficiency of 95.8 % and completely eliminated most complex organics revealed by gas chromatography-mass spectrometry (GC-MS). Denaturing gradient gel electrophoresis (DGGE) analysis revealed differences in the microbial community structures of the three reactors. Further identification of the microbial populations suggested that the presence of Lactobacillus and Prevotella in CSTR played an active role in the production of volatile fatty acids (VFAs). The most diverse microorganisms with analogous distribution patterns of different layers were observed in the EGSB reactor, and bacteria affiliated with Firmicutes, Synergistetes, and Thermotogae were associated with production of acetate and carbon dioxide/hydrogen, while all acetoclastic methanogens identified belonged to Methanosaetaceae. Overall, microorganisms associated with the ability to degrade cellulose, hemicellulose, and other biomass-derived organic carbons were observed in the combined system. The results presented herein will facilitate the development of an improved cellulosic ethanol production wastewater treatment system.
论文标题Factors affecting microalgae harvest efficiencies using electro-coagulation-flotation for lipid extraction
作者 Dawei Zhang, Yanling Yu, Chao Li Chunyan Chai, Yujie Feng
期刊名称Rsc Advances
期卷2015, 5 (8
简单介绍Microalgae harvesting is a relatively costly process in microalgae biodiesel production. In this study, electrocoagulation-flotation (ECF) was employed to harvest microalgae (Chlorella vulgaris). Higher current density achieved higher collection efficiency, but also resulted in higher energy consumption and increased levels of dissolved aluminium. At the same ratio of current density to initial cell density, collection efficiency decreased from 99.0% of 0.24 g L611 to 30.5% of 1.17 g L611 when the electrolysis time was 20 min. For stirring and aeration, the highest collection efficiency was 98.4%, obtained by stirring at 50 rpm for 20 min. This efficiency was nearly equal to the highest collection efficiency for aeration: 98.3% for 50 mL min611 aeration at 30 min. Acidic and neutral culture conditions were beneficial due to the positively charged aluminium species in the culture; higher collection efficiencies (more than 98%) occurred with pH levels of 5–7 after 20 min. The lowest energy consumption of 0.61 kW h kg611 was achieved at pH 5. In this research, ECF exhibited higher collection efficiency (99.4%) as compared to the 93.5% collection efficiency of chemical flocculation (Al2(SO4)3).
论文标题Winter crop and residue biomass potential in China
作者Ryan Baxter, Gary Feyereisen, Yanling Yu, Tom L Richard
期刊名称Biofuels
期卷2011, 2(5)
简单介绍Background: To estimate the scale of bioenergy winter crops and summer crop residue opportunities inChina, winter rye (Secale cereal) yields were predicted using RyeGro, while straw production from corn,wheat and rice was calculated using a global agricultural database. Results: Potential winter rye biomassyields ranged from 11,099,000 to 23,745,700 Mg, while summer crop residues totaled 365,600,000 Mg afterdiscounting for losses and alternative uses. Conclusion: Widespread existing double-cropping systems, aswell as low winter precipitation and temperatures in China’s northern regions, limit the potential to directly increase biomass production using winter crops. However, winter crop synergies can increase sustainable harvests of summer crop residues, allowing China to provide a significant fraction of its energy needs from integrated food and biomass production systems.
论文标题Onsite bio-detoxification of steam-exploded corn stover for cellulosic ethanol production
作者Yanling Yu, Yujie Feng, Chen Xu, Jia Liu, Dongmei Li.
期刊名称 Bioresource Technology
期卷 Volume 10
简单介绍In the process of ethanol production from steam-exploded corn stover (SECS), a cellulose-degradationstrain of Aspergillus nidulans (FLZ10) was investigated whether it could remove the inhibitors releasedfrom steam exploded pretreatment , and thereby be used for biological detoxification on Saccharomycescerevisiae. The results showed that FLZ10 removed 75.2% formic acid, 53.6% acetic acid, and 100%hydroxymethyl furfural (5-HMF) and furfural from the hydrolysate washed from SECS after 72 h cultivation.A cellulase activity of 0.49 IU/ml was simultaneously produced while the biological detoxificationoccurred. An ethanol yield of 0.45 g/g on glucose was obtained in the hydrolysate biodetoxified byFLZ10. The glucose consumption rate of FLZ10 was much lower than that of S. cerevisiae, thereby ithad little competition with S. cerevisiae on glucose consumption. Based on SECS to ethanol mass balanceanalysis, with the onsite bio-detoxification, fermentation using S. cerevisiae effectively converted monomericglucose with 94.4% ethanol yield.
论文标题Degradation of raw corn stover powder (RCSP) by an enriched microbial consortium and its community structure
作者Yujie Feng , Yanling Yu, Xin Wang, Youpeng Qu, Dongmei Li, Weihua He, Byung Hong Kim
期刊名称Bioresource Technology
期卷Volume 102
简单介绍A microbial consortium with a high cellulolytic activity was enriched to degrade raw corn stover powder (RCSP). This consortium degraded more than 51% of non-sterilized RCSP or 81% of non-sterilized filter paper within 8 days at 40 °C under facultative anoxic conditions. Cellulosome-like structures were observed in scanning electron micrographs (SEM) of RCSP degradation residue. The high cellulolytic activity was maintained during 40 subcultures in a medium containing cellulosic substrate. Small ribosomal gene sequence analyses showed the consortium contains uncultured and cultured bacteria with or without cellulolytic activities. Among these bacteria, some are anaerobic others aerobic. Analyses of the culture filtrate showed a typical anoxic polysaccharide fermentation during the culturing process. Reducing sugar concentration increased at early stage followed by various fermentation products that were consumed at the late stage.
论文标题降解未处理纤维素厌氧混合菌群的筛选及功能

期卷43 (2)
简单介绍为获得高效稳定的原木质纤维素降解微生物,利用限制性培养手段,从瘤胃残渣中筛选出了可以体外培养、分解能力强且性能稳定的纤维素厌氧降解菌群FYG - 2. 该菌群在38. 5 ℃,pH6. 4 ~ 6. 8 条件下,5 d内可以使1. 00 g 滤纸完全崩解. 转接30 代,其降解性能仍保持稳定,且纤维素底物的灭菌与否均不影响其分解. 以底物失重率、纤维素酶活和葡萄糖质量浓度为参数,考查了FYG - 2 对纤维素的分解特性: 同预处理后的木质纤维素相比,FYG - 2 更易于降解天然木质纤维素. 在初始接菌量为15%,培养3 d 时,FYG - 2 的酶活最高( 159. 7 IU) . 从FYG - 2 中分离出7 株纯菌,但其纤维素酶活均低于FYG - 2. 纯菌回接实验表明,混合菌群中的协同作用很可能存在于纤维素降解菌与非纤维素降解菌之间或存在于可培养微生物与不可培养微生物间.

期卷2016:1-8
简单介绍The high chroma of cellulosic ethanol production wastewater poses a serious environmental concern; however, color-causing compounds are still not fully clear. The characteristics of the color compounds and decolorization of biologically treated effluent by electro-catalytic oxidation were investigated in this study. Excitation-emission matrix (EEM), fourier transform infrared spectrometer (FTIR), UV-Vis spectra, and ultrafiltration (UF) fractionation were used to analyze color compounds. High chroma of wastewater largely comes from humic materials, which exhibited great fluorescence proportion (67.1 %) in the biologically treated effluent. Additionally, the color compounds were mainly distributed in the molecular weight fractions with 3–10 and 10–30 kDa, which contributed 53.5 and 34.6 % of the wastewater color, respectively. Further decolorization of biologically treated effluent by electro-catalytic oxidation was investigated, and 98.3 % of color removal accompanied with 97.3 % reduction of humic acid-like matter was achieved after 180 min. The results presented herein will facilitate the development of a well decolorization for cellulosic ethanol production wastewater and better understanding of the biological fermentation.
论文标题Carbon Footprint Analyses of Mainstream Wastewater Treatment Technologies under Different Sludge Treatment Scenarios in China
作者Chunyan Chai, Dawei Zhang, Yanling Yu, Yujie Feng , and Man Sing Wong
期刊名称Water
期卷2015, 7(3)
简单介绍With rapid urbanization and infrastructure investment, wastewater treatment plants (WWTPs) in Chinese cities are putting increased pressure on energy consumption and exacerbating greenhouse gas (GHG) emissions. A carbon footprint is provided as a tool to quantify the life cycle GHG emissions and identify opportunities to reduce climate change impacts. This study examined three mainstream wastewater treatment technologies: Anaerobic-Anoxic-Oxic (A-A-O), Sequencing Batch Reactor (SBR) and Oxygen Ditch, considering four different sludge treatment alternatives for small-to-medium-sized WWTPs. Following the life cycle approach, process design data and emission factors were used by the model to calculate the carbon footprint. Results found that direct emissions of CO2 and N2O, and indirect emissions of electricity use, are significant contributors to the carbon footprint. Although sludge anaerobic digestion and biogas recovery could significantly contribute to emission reduction, it was less beneficial for Oxygen Ditch than the other two treatment technologies due to its low sludge production. The influence of choosing "high risk" or "low risk" N2O emission factors on the carbon footprint was also investigated in this study. Oxygen Ditch was assessed as "low risk" of N2O emissions while SBR was "high risk". The carbon footprint of A-A-O with sludge anaerobic digestion and energy recovery was more resilient to changes of N2O emission factors and control of N2O emissions, though process design parameters (i.e., effluent total nitrogen (TN) concentration, mixed-liquor recycle (MLR) rates and solids retention time (SRT)) and operation conditions (i.e., nitrite concentration) are critical for reducing carbon footprint of SBR. Analyses of carbon footprints suggested that aerobic treatment of sludge not only favors the generation of large amounts of CO2, but also the emissions of N2O, so the rationale of reducing aerobic treatment and maximizing anaerobic treatment applies to both wastewater and sludge treatment for reducing the carbon footprint, i.e., the annamox process for wastewater nutrient removal and the anaerobic digestion for sludge treatment.

期刊名称Journal of Hazardous Materials
期卷2010, 175:
简单介绍The adsorption behavior of 17α-ethinylestradiol (EE2) onto inactivated sludge was investigated to assess the function of adsorption on EE2 removal in activated sludge system. The adsorption equilibrium of EE2 can be achieved in 5.0 h at the research temperature and the adsorption process could be well described by pseudo-second-order model. The equilibrium data at different temperatures were fitted by a linear regression. The thermodynamics analysis revealed that EE2 adsorption onto inactivated sludge was spontaneous (ΔG = ?15.18 to ?16.35 kJ/mol), enthalpy-driven (ΔH = ?27.2 kJ/mol), entropy-retarded (ΔS = ?39.18 J/(mol K)), and mainly physical adsorption. Effects of pH, ionic strength and coexisting organic matters (methanol and bisphenol A) on EE2 adsorption onto inactivated sludge were also examined. The amounts of EE2 equilibrium adsorption ability were unchanged as the pH values increasing from 2.0 to 6.0, but decreased from 2.14 to 1.43 mg/g MLSS when the initial EE2 concentration was 5.0 mg/L as pH above 6.0. The adsorption capacities were first increased from 2.19 to 2.50 mg/g MLSS, then sharply decreased and stabilized at 1.12 mg/g MLSS during the ionic strength was adjusted from 0 to 1 mol/L. Methanol (0.4–5%, v/v) and bisphenol A (0–200 mg/L) in the mixed liquor can decrease the adsorption capacity of EE2 from 2.19 to 1.39 and 0.75 mg/g MLSS, respectively.

期卷2009, 43 (
简单介绍Corn stover is usually treated by an energy-intensive or expensive process to extract sugars for bioenergy production. However, it is possible to directly generate electricity from corn stover in microbial fuel cells (MFCs) through the addition of microbial consortia specifically acclimated for biomass breakdown. A mixed culture that was developed to have a high saccharification rate with corn stover was added to single-chamber, air-cathode MFCs acclimated for power production using glucose. The MFC produced a maximum power of 331 mW/m2 with the bioaugmented mixed culture and corn stover, compared to 510 mW/m2 using glucose. Denaturing gradient gel electrophoresis (DGGE) showed the communities continued to evolve on both the anode and corn stover biomass over 60 days, with several bacteria identified including Rhodopseudomonas palustris. The use of residual solids from the steam exploded corn stover produced 8% more power (406 mW/m2) than the raw corn stover. These results show that it is possible to directly generate electricity from waste corn stover in MFCs through bioaugmentation using naturally occurring bacteria.

期卷2015, 66:1
简单介绍采用间歇式水热预处理方法,考察了不同水热预处理温度和处理时间对玉米秸秆主要成分变化的影响以及水热预处理后的纤维素酶解效率。在180~220℃,10~25 min范围内,随温度升高和时间延长预处理后半纤维素移除率和纤维素损失率也随之增大,但木质素质量并未减少反而有所增加。在210℃,25 min时得到最大半纤维素移除率为86.0%。以半纤维素移除率、木质素移除率和纤维素损失率为因变量,处理温度和处理时间为自变量通过多元线性回归分析或二次方程(多元线性回归方程拟合度不佳时)拟合分别获得回归模型。模型显示处理温度和处理时间对三者均具有显著影响。分析敏感性显示处理温度对三种因变量的影响均大于处理时间。经210℃,20 min处理后,纤维素酶解率最高为76.2%,继续提高处理温度和延长处理时间半纤维素移除率提高,但纤维素酶解率下降。

简单介绍为获得高效稳定的原木质纤维素降解微生物,利用限制性培养手段,从瘤胃残渣中筛选出了可以体外培养、分解能力强且性能稳定的纤维素厌氧降解菌群FYG-2.该菌群在38.5℃,pH6.4~6.8条件下,5 d内可以使1.00 g滤纸完全崩解.转接30代,其降解性能仍保持稳定,且纤维素底物的灭菌与否均不影响其分解.以底物失重率、纤维素酶活和葡萄糖质量浓度为参数,考查了FYG-2对纤维素的分解特性:同预处理后的木质纤维素相比,FYG-2更易于降解天然木质纤维素.在初始接菌量为15%,培养3 d时,FYG-2的酶活最高(159.7 IU).从FYG-2中分离出7株纯菌,但其纤维素酶活均低于FYG-2.纯菌回接实验表明,混合菌群中的协同作用很可能存在于纤维素降解菌与非纤维素降解菌之间或存在于可培养微生物与不可培养微生物间.
论文标题酸处理秸秆生产乙醇过程中解毒方法的比较
作者于艳玲,冯玉杰,刘佳,高霏
期刊名称化工进展
期卷2008:108-1
简单介绍以糖浓度、乙醇浓度和乙醇产率为指标,比较了水洗、 ca(OH)2过量、加大酿酒酵母接种量三种方法在以酸处理秸秆为原料发酵生产乙醇过程中的解毒效果.结果表明,水洗法和Ca(OH)2法都可以解除抑制 物对纤维素酶和酵母的抑制作用,但是这两种方法的最大乙醇产率仅分别是理论产率的57.5%和74.2%,这是因为在解毒过程中,这两种解毒方法造成了原 料损失.加大酵母接种量法(10 g/L)既能通过细胞的代谢作用解除抑制物对纤维素酶的抑制,又保留了部分细胞的活性,在SSF(simultaneus saccharification and fermentation)工艺中,发酵16 h,乙醇产率达到理论产率的95.8%.
论文标题以玉米秸秆为底物的纤维素降解菌与产电菌联合产电的可行性
作者冯玉杰,王鑫,王赫名,于艳玲,李冬梅
期刊名称环境科学学报
期卷2009,29( 1
简单介绍利用单室空气阴极微生物燃料电池(MFC)反应器,以玉米秸秆为底物,以本实验室筛选和保存的纤维素降解菌Chaetomium sp.和Bacillus sp.,以及纤维素降解混合菌PCS-S和H-C为秸秆降解的生物催化剂,探讨了以汽爆秸秆固体为底物进行微生物产电的可行性.结果表明,在MFC系统内,纤维素降解纯菌和混合菌均能使纤维素降解,但产生的电压很低(<90mV,1000Ω),升高温度(30~38.5℃)对电压输出无明显影响.单独以生活污水作为菌源不能直接降解秸秆产电.只有将H-C和生活污水(产电菌源)混合作为接种体,MFC才能获得较高的电压输出.此时得到的以汽爆秸秆固体作为底物时的最大功率密度为406mW.m-2,仅比葡萄糖作为底物时所得到的最大功率密度510mW.m-2低20%.
