Background: The bacterial destructing activity toward pesticides has been the focus of research in last few decades. Hexachlorobenzene is included organochlorine group that are prohibited for use. However, large hexachlorobenzene amounts still concentrated soil, stressing relevance on hexachlorobenzene-destroying bacteria. Methods: ability to destroy by Comamonas testosteroni UCM B-400, B-401, ...

in order to evaluate the effects of different levels of potassium and nitrogen on nitrogen use efficiency (nue) and yield of rapeseed (hyola 401), a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on a complete randomized block design with 3 replications for two years (2008-2010). the first factor was pure potassium fertilizer in three l...

Abstract Acid mist inhibitor is an effective additive for suppressing the generation of acid during electrowinning process. However, traditional has a low current efficiency, leading to high energy consumption. Thus, novel inhibitors are crucial development industry. In this paper, three new (Famigo ® FS-101, Famigo FS-301, and FS-401) used in zinc process, while mechanism action characterized ...
