The enzyme that converts atmospheric nitrogen to ammonia in the nodules of the rhizobium/plant symbiosis is The greatest source for fixing molecular nitrogen (N_2) to ammonium (NH_4^+) in terrestrial environments is Why is NH_4^+ toxic to all organisms if allowed to accumulate beyond -0.5 mM? The statement above is false - NH_4^+ is not toxic but is instead an important source of nitrogen. NH_4^+ reacts with NADPH (and NADH) to reduce the reducing power in a cell. At pH 7...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
