摘要：

The objective of this study was to investigate biosurfactant production in solid state by Aspergillus fumigatus in fixed-bed column bioreactors using substrate based on agricultural residues. Without a supplementary carbon source the highest emulsifying activity (EA) was 11.17 emulsifying units (EU) g(-1) of substrate at an aeration rate of 148 mL h(-1)g(-1) but in the presence of diesel oil the highest EA value was 9.99 EU g(-1) at an aeration rate of 119 mL h(-1)g(-1) of substrate while supplementation with soya oil resulted in only 8.47 EU g(-1) of substrate at an aeration rate of 119 mL h(-1)g(-1).
