Abstract: Corn flour was used as raw materials, Monascus M3428 was selected. Monascus pigment was produced by liquid-state fermentation. Through the orthogonal experiment to study the influence of the liquid volume of flasks, the table rotation，the fermentation time and the fermentation fluid initial pH to Monascus pigments production. The optimal fermentation condition was obtained: 100 mL fermentation fluid in 500 mL flasks; rotational speed of 150r/min; fermentation time of 14d; fermentation fluid initial pH of 4.5. Further preliminarily study the inhibition function against E.coli, Bacillus subtilis, White aureus, Yeast and Mycete. The results was obtained: Monascus pigments had strong inhibition function against Bacillus subtilis, had weak inhibition function against E.coli and Yeast, but had no inhibition function against Staphylococcus albus or Mycete.

Abstract: The SPI was applied in food industry widely, but its functionalities may change during storage. The effect of store temperature, time, RH and package material on emulsibility and the component of SPI were studied, when SPI was packaged in 100% N₂ and Al, 80%N₂:20%CO₂ and Al, 60%N₂:40% CO₂ and Al, vacuum and Al, white paper/plastic/HDPE, and PE and then stored for 5 months in the conditions of RH 80% and 30°C. It was observed by SDS-PAGE that the subunit of SPI disaggregated and molecules aggregated. Comparing the functionalities of SPI with different packaging material, it was shown that the sequence of the barrier property of material to T and RH was Al packaging>factory packaging>PE packaging. Analyzed by relatedness, it was shown that the 7S/11S of SPI with PE packaging storage was not significant with emulsibility. The content of -SH with PE was significantly positive with emulsibility (EAI 0.975**/ESI 0.985**), but the -S-S- of SPI in PE was significantly negative (EAI -0.975**/ESI -0.967**) correlation with emulsibility.

Abstract: In order to investigate the characteristic of atmospheric particles, TSP, PM₁₀ and PM_2.5 were collected in winter and non-winter. This study investigates the size distribution and elemental characteristics of atmospheric particles. The results show that PM_2.5 makes a great contribution to TSP, which changes with the concentration of TSP. PM_2.5/ PM₁₀ specially reaches the highest value, increased from 53.5% to 87.2%. It can indicate that the main pollution sources are fine particles from man-made pollution. Others, PM_2.5/TSP and TSP are not strictly proportional relationship. The concentration of the elements in TSP is higher than in PM_2.5, which are primarily present in coarse particles. While the contribution of S is the highest among them, in particular the contribution of S in PM_2.5 reaches 33.8%. This is mainly due to coal-fired in winter, and fine particulate accounts for large percentage in coal dust.

Abstract: Inhibitory effects of the combination of submerged macrophytes and aquatic plants on the growth of algal community in Landscape water of Hefei city were evaluated. The nutrient reduction of the water through the aquatic plants adsorption was monitored. In the coexistence culture system of submerged macrophytes (Myriophyllum aquaticum and Elodea densa) and aquatic plants (Iris germanica L.、Purple Lythrum、Cyprus alternifolius、Canna lily), the combination of Myriophyllum aquaticum and Cyprus alternifolius can remove the NH₄⁺-N, TN, meanwhile lower the chlorophyll and inhibited the growth of algae efficiently.

Abstract: As an important oxidants, Chlorine dioxide was more useful in the decolorization of Reactive Red KE-3B, Reactive Blue KN-R, Reactive Red X-3B and Reactive Blue X-BR. It was found that the optimal pH=8，the optimal initial dosage of ClO₂ and reaction time were 60 mg*L^-1 and 15 min, respectively. The optimal reaction temperature of dyes were 80°C. Chlorine dioxide seems to be viable method for achieving significant decolorization of dying industry wastewater.

Abstract: Degradation of acid dye wastewater has been studued by using resin D072 load Fe²⁺ as heterogeneous Fenton catalyst. The effects of the initial PH of solution,the H₂O₂ adding doses,the amount of catalyst and the reaction temperature on the degradation of acid dye wastewater have been investigated in detail. According to experimental results, the optimal pH was pH3, the H₂O₂ adding doses was 333mg/L, the amount of catalyst and the reaction temperature were 10g/L and 27°C, respectively.

Abstract: In order to improve treatment efficiency of coke plant wastewater with membrane bioreactor, this paper has discussed the treatment efficiency of coke plant wastewater with membrane bioreactor and contamination of membrane after added bioflocculant. Results show that after 6 days running, effluent water goes to stable, all of the concentration of phenols is below 10 mg/L, average concentration of phenols in effluent water is 3.95mg/L, and the lowest is 1.11mg/L. The removal efficiency of phenols keep to 98.9% at the end of run，and the highest is 99.6%. Concentration of NH3-N is maintained at 10mg/L，removal efficiency is 95.8%. Removal efficiency of COD comes to 96.5%, and the concentration of COD in effluent water is 43mg/L. At the beginning, the Flux of membrane is 14.3ml/min. At the end of running, it is 7.3ml/min with bioflocculant added, and it becomes 6.9ml/min with no bioflocculant added, which indicates that there is no evident effect of bioflocculant added on membrane flux.

Abstract: Laboratory-scale sequencing batch reactors (SBRs) were operated on activated sludge processes were used to study enhanced biological phosphorus removal (EBPR) from wastewater. Polyphosphate-accumulating microorganisms (PAOs) play an important role during the enhanced biological phosphorus removal (EBPR) process. Fluorescence in situ hybridization (FISH) was applied to assess the proportions of microorganisms in the sludge. The aim of this study was to optimize hybridization of PAOMIX and RHC439 probes by orthogonal design. Orthogonal optimization test of the four factors were conducted under the individual three levels. The optimal hybridizition conditions were as follow: hybridization temperature 46°C, hybridization time 2.5h, washing time 15min, formamide concentration 35%(PAOMIX probe); hybridization temperature 50°C, hybridization time 2.5h, washing time 20min, formamide concentration 20% (RHC439 probe).

Abstract: According to the IPCC WGII Fourth Assessment Report, more than 89% of observational data series and studies are consistent with the greenhouse gas change, which is produced from human activities, as a response to global warming. In the previous point, the tourism and leisure industry is regarding as the non-smokestack industry. However, with an increase of leisure and tourism activities, the carbon dioxide emission and energy use have been growing. Recognizing these risks, the Agenda 21 for the Tourism and Travel Industry promulgated by the World Travel and Tourism Council, the WTO and the Earth Council addressed energy consumption as a key issue of concern. The buildings are a major part of the leisure industry. Therefore, this work aims to investigate the energy use and carbon emission of a hotel building, located in the middle of Taiwan, for four seasons. The consumption generated from each visitor activating in the building also were conducted. The results will be used as a reference for further investigations into the reduction of energy use and carbon emission in the leisure buildings. By investigation of proposed carbon neutral model, the willing price to pay is highly larger than both of the shifted and non-shifted prices. Most people has always inclined to pay for self-related GHG emission. Green development and sustainable operations in the leisure industry should be attended because the real costs of a green building are less than you think.

Abstract: All-silica zeolite beta (BEA) was tested for the ability to remove nitrobenzene and benzoic acid from aqueous solution. The effect of contact time, temperature, initial concentration and initial pH were investigated in a batch reactor system. Adsorption of nitrobenzene decreased with increase in temperature. The equilibrium isotherm was L-shaped. Nitrobenzene adsorption was independent of pH. Adsorption of benzoic acid increased with increasing temperature from 5 °C to 22 °C and decreased with increasing temperature from 22°C to 32 °C. The equilibrium isotherm was approximately S-shaped. Benzoic acid adsorption was dependent of pH. At pH8.0, benzoic acid can also be adsorbed effectively. The results above confirmed that BEA had the potential to be utilized as relatively effective adsorbent for nitrobenzene and benzoic acid removal.
