Schrödinger's microbes: Tools for distinguishing the ...

While often obvious for macroscopic organisms, determining whether a microbe is dead or alive is fraught with complications. Fields such as microbial ecology, environmental health, and medical microbiology each determine how best to assess which members of the microbial community are alive, according to their respective scientific and/or regulatory needs.

Microbial Versus Chemical Leaching of Chalcopyrite ...

A number of hydrometallurgical treatment methods are being developed to extract copper from chalcopyrite flotation concentrate including microbial leaching and ferric sulfate leaching. However, chalcopyrite is difficult to process efficiently by hydrometallurgical methods as it exhibits slow reaction kinetics. Comparative leaching tests do not always satisfactorily explain or predict observed ...

Orange I | C16H11N2NaO4S PubChem

Due to the ionic nature of Acid Orange 20, the retention of this dye by ionexchange processes in soil may slow down or prevent leaching, depending on the soil type. The volatilization of the dye from moist soil surfaces to air will not be important as Acid Orange 20 is an ionic compound.
