Biological guided fractiontion
WebA bioassay-guided isolation method was developed with Aspergillus fumigatus and Rhodotorula mucilaginosa as target organisms. The bioassay was a dilution bioassay and was performed after each fractionation step. The isolation procedure was based on fractionation of cell-free supernatants using solid phase extraction (SPE) and reversed- WebNational Center for Biotechnology Information
