The objective of this study was to study the simultaneous biodegradation of Ni-citrate complexes and removal of Ni from solutions by Pseudomonas alcaliphila. Adding excess citrate to 1:1 Ni-citrate complexes promoted the degradation of the complexes and removal of Ni. The alkaline pH generated by the metabolism of excess citrate caused partial dissociation(More)
Denitrification and dissimilatory nitrate reduction to ammonium (DNRA) were considered two alternative pathways of dissimilatory nitrate reduction. In this study, we firstly reported that both denitrification and DNRA occurred in Pseudomonas alcaliphila strain MBR with an electrode as the sole electron donor in a double chamber bio-electrochemical system(More)
Although microorganisms have the potential to reduce metals, products with elementary forms are unusual. In the present study, a strain of Pseudomonas sp. MBR was tested for its ability to reduce metal ions to their elementary forms coupled to biomineralization under aerobic conditions. The Pseudomonas sp. MBR strain was able to reduce metals such as(More)
Liquid phase oxidation process using chelated iron solution is among the most promising techniques for the hydrogen sulfide removal due to its double advantage of waste minimization and resource recovery. Regeneration of chelated iron is a core reaction in this process. Regeneration of chelated iron in acidic solution is very difficult. In this paper, a(More)
As professional, academic and accrediting bodies have periodically reviewed the need for and content of foundational college curricula in information management, a broad-based consensus has emerged as to what is to be covered in the standard management information systems (MIS) course. Within U.S. business schools today, there is little debate over the need(More)
Resource management continuity is indispensable against illegal resource dissemination and usage in open environment, which should be guaranteed by an effective constraint management mechanism. In detail, it includes two requirements, (1) guaranteeing resource dissemination continuability and purpose-consistency on the dissemination topology, and (2)(More)
