Our aim was to determine the effects of two secondary metabolites secreted by Trichoderma harzianum, pachybasin and emodin, on the mycoparasitic coiling behavior and cAMP content of T. harzianum. The number of T. harzianum coils around Nylon 66 fiber was increased in the presence of R. solani. The number of T. harzianum coils around R. solani hyphae and Nylon 66 fiber were significantly increased in the presence of pachybasin and emodin. The cAMP level in T. harzianum was significantly increased by close contact with R. solani and much higer cAMP level in the presence of exogenous pachybasin and emodin. A cAMP inhibitor diminished the effect of pachybasin and emodin on T. harzianum coiling around Nylon 66 fiber. The results suggest that pachybasin and emodin mediate the increase in the number of Trichoderma mycoparasitic coils via cAMP signaling. This is the first report to suggest that pachybasin and emodin play roles in the biocontrol mechanism of Trichoderma. © 2012 American Chemical Society.

Adopting a laboratory-scaled electrodialysis (ED) process, we investigate the performance of a monovalent anion exchange permselective membrane in the reduction of the concentration of sulfate ions during the production of mineral source water from deep sea water (DSW). The dependence of the separation efficiency of anions on the operating time and the applied DC voltage is investigated based on a brine having salinity of about 15% prepared from DSW. The experimental results reveal that if the applied DC voltage is high, the change in the liquid volume during ED is dominated by the ions transported and the effect of electroosmosis. In addition, the amount of chloride ions transported correlates roughly linearly with the operating time, and the transport of sulfate ions is found to be blocked by chloride ions, presumably because of that the pore size of the permselective layer is close to the size of sulfate ions. © 2010 American Institute of Chemical Engineers (AIChE).

Hydrogen (H2) production potential of water hyacinth (WH) and beverage wastewater (BW) mixture in powder and pellet form at various combination ratios were evaluated. Batch co-fermentation results showed peak biogas production of 105.5mL and H2 production of 55.6mL at the combination ratio of 1.6g WH and 2.4g BW in pellet form. With the same ratio in pellet form, the maximum H2 production rate 542mL H2/L-d, maximum specific H2 production rate 869mL H2/g VSS-d and H2 yield 13.65mL/g feedstock were obtained, and were 88, 88 and 34% higher than its powder form. The predominant soluble metabolite was acetate in the concentration of 1059-2639mg COD/L (40-79% of total metabolites) in most runs during co-fermentation of mixed feedstock. Carbon-to-nitrogen ratio and the physical form of the combined feedstock are essential criteria for optimum H2 production. Co-fermentation also alleviates the waste disposal problem of the industries. © 2012 Elsevier Ltd.

The porous ceramic material can reduce the air flow, but also can achieve uniform air pressure, good distribution, and can provide sufficient float height and adsorption force required by work, and has been gradually applied to the conveying & precision positioning system for large-size TFT-LCD glass substrate and relevant process equipment. Therefore, this study discussed the above problems from reference and theoretical analysis, characteristics of porous ceramic, design and development of aerostatic platform and related technology application and so on. The Result shows the Air Bearing Clearance. Bearing capacity increases with the increase of restrictor's diameter, but the stiffness decreases with the increase of restrictor's diameter. Although stiffness reduced, working clearance corresponding to the stiffness increased gradually. The variation properties of air flow and bearing capacity of bearing are the same, increasing with the increase of restrictor's diameter. that the porous materials can float a larger height under the same pressure compared to traditional Restrictors, and can indeed meet the high performance needs.

Characterized as rich mineral substances, low temperature, few bacteria, and stability with numerous implementation aspects on aquaculture, food, drinking, and leisure, the deep sea water (DSW) development has become a new industry in the world. It has been report that marine algae contain various biologically active compounds. This research focued on the affections in cultivating Sagrassum cristaefolium with different concentration of deep sea water(DSW) and surface sea water(SSW). After two and four weeks, the total phenolic contents were compared in Sagrassum cristaefolium culturing with different ways, and the reductive activity of them was also be tried with potassium ferricyanide. Those fresh seaweeds were dried with oven and were ground to powder. Progressively, the marine algae we cultured was extracted by water under the condition with heating them at 90°C for 1hr.The total phenolic contents were be executed using Folin-Ciocalteu method. The results were explaining as follows: the highest total phenolic contents and the best reductive ability of all could be observed on the 1/4 proportion of DSW to SSW culturing in two weeks. Furthermore, the 1/2 proportion of DSW to SSW also showed good reductive ability and plentiful phenolic compositions. Finally, we confirmed that difference proportion of DSW and SSW is the major point relating to ether the total phenolic components or the reductive ability in the Sagrassum cristaefolium. In the future, we will use this way to mass production the marine algae or other micro algae on industry applications.

Engineering strategies were applied in this study to promote the autotrophic growth and oil accumulation of an oil-rich indigenous microalga Chlorella sorokiniana CY1 using deep-sea water (DSW) as the medium. The addition of 20% DSW to the culture medium effectively enhanced the cell growth and oil accumulation of C. sorokiniana CY1, leading to an oil content and biomass concentration of 61.0% and 3.0. g/L, respectively. The microalga strain was also successfully grown in 5. L plastic bag-type photobioreactor on DSW-amended medium, obtaining an oil content, biomass concentration, and biomass productivity of 51.7%, 2.4. g/L, and 176.6. mg/L/d, respectively. The semi-batch cultivation resulted in stable biomass production, but the lipid production efficiency slightly decreased. The main fatty acids in the lipid produced from C. sorokiniana CY1 were palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2) and eicosenoic acid (C20:1). This lipid quality is suitable for biodiesel production. © 2013 Elsevier B.V.
