Abstract:Geoactive fungi such as Aspergillus niger play a significant role in bioweathering processes and element cycling. These organisms are able to secrete a range of organic acids, such as oxalic acid, into their microenvironment. This enables them to mediate mineral dissolution, leading to metal solubilization and precipitation in the form of secondary biominerals. In this investigation, such biotransformation processes were explored as a means of cobalt bioprocessing, an E-tech element identified as being of key … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
