Bioremediation potential of filamentous fungi in methylene blue: Solid and liquid culture media
ABSTRACT The evaluation of the bioremediation potential of microbial with dyes in solid and liquid culture media has been described, but prior studies have not mentioned which culture method is most appropriate for selection of microorganisms. Therefore, the aim of this work was to evaluate the bior...
