Research on the New Type of the Biological Suspended Filler

At present, much research has been down to deal with urban sewage in the world to overcome the problem of urban water shortage. And many sewerage treatment systems need to be transformed to meet the requirement of city development. The method of using Bio-film to deal with urban sewage has gotten more attention by the countries of the world. Hydrophilic modified biological suspended filler is one of core technologies in the sewage treatment system which affects the efficiency, energy consuming, stability and reliability of the urban sewerage treatment. In this paper the new hydrophilic modified biological suspended filler is researched systematically and the processing technique is studied. The hydrophilic and mechanic performance of the suspended filler was tested. Results shown that the new type of hydrophilic modified suspended filler has good hydrophilic and meets the demand of urban sewage treatment system, which has great meaning and value in solving the problem of urban sewage and recycling

Research on the Hydrophilic Modified of LDPE for the New Biological Suspended Filler

Urban sewage is one of the main pollution sources of the city, which pollute soil, deteriorate the water quality and increase the water shortages and urban load. LDPE is low cost and widely used as the basic material of wastewater treatment, but LDPE’s hydrophilic is not good enough to meet the need of suspended filler in wastewater treatment. In this paper the hydrophilic modified of LDPE for the new biological suspended filler was studied and the preparation and processing technique based on LDPE was researched. The hydrophilic and mechanic performance of the hydrophilic modified materials was tested. Results shown that the new type of hydrophilic modified materials has good hydrophilic and meets the demand of urban sewage treatment. The research on the new suspended filler materials has great meaning in solving the problem of urban sewage and recycling

Magnaporthe oryzae effector MoSPAB1 directly activates rice Bsr-d1 expression to facilitate pathogenesis

Abstract Fungal pathogens typically use secreted effector proteins to suppress host immune activators to facilitate invasion. However, there is rarely evidence supporting the idea that fungal secretory proteins contribute to pathogenesis by transactivating host genes that suppress defense. We previously found that pathogen Magnaporthe oryzae induces rice Bsr-d1 to facilitate infection and hypothesized that a fungal effector mediates this induction. Here, we report that MoSPAB1 secreted by M. oryzae directly binds to the Bsr-d1 promoter to induce its expression, facilitating pathogenesis. Amino acids 103-123 of MoSPAB1 are required for its binding to the Bsr-d1 promoter. Both MoSPAB1 and rice MYBS1 compete for binding to the Bsr-d1 promoter to regulate Bsr-d1 expression. Furthermore, MoSPAB1 homologues are highly conserved among fungi. In particular, Colletotrichum fructicola CfSPAB1 and Colletotrichum sublineola CsSPAB1 activate kiwifruit AcBsr-d1 and sorghum SbBsr-d1 respectively, to facilitate pathogenesis. Taken together, our findings reveal a conserved module that may be widely utilized by fungi to enhance pathogenesis
