Mass transfer studies on biological denitrification in fluidized bed bioreactor.
A fluidized bed bioreactor has been used to carry out biological denitrification in the present work as it offers many advantages over other types of reactors. Plastic beads of low density (1055 kg/m3) were used as fluidizing media with Pseudomonas stuzeri, a denitrifying microorganism immobilized on them. The denitrification rate under different operating conditions was studied. The results of...

چکیده در دنیای پیچیده ی امروز، تغییرات زیادی در زندگی بشری در حال وقوع اند و شاهد رقابت های بسیار فشرده ی جوامع در دستیابی به فناوری برتر و قدرت بیشترهستیم. به نظر می رسد که فرد وجامعه مجبورند به طریقی در وضعیت خویش دگرگونی ایجاد کنند تا از قافله ی علم، فناوری، و پیشرفت عقب نمانند. رشته مطالعات ترجمه نیز از این قاعده مستثنا نیست. علی رغم وسعت روز افزون پژوهش در این حوزه و میان رشته ای بودن مطال...

متن کاملDenitrification in the Riverstrahler Model
Riverstrahler is a process-based model of nutrient transfer and biogeochemical functioning of large river systems (Billen et al., 1994; Garnier et al, 1995; Billen & Garnier, 2000) at the seasonal scale. Its essence lies in the coupling of an original representation of the drainage network, partly based on the streamorder classification of Strahler (1957), with a detailed model of biogeochemica...
متن کاملMicroaerobic denitrification in Neisseria meningitidis.
The major aetiological agent of human bacterial meningitis is Neisseria meningitidis. During the course of disease and host colonization, the bacterium has to withstand limited oxygen availability. Nitrogen oxide and nitrogen oxyanions are thought to be present, which may constitute an alternative sink for electrons from the N. meningitidis respiratory chain. A partial denitrification pathway i...
