Fig. 5From: Effect of biosurfactant sophorolipids on Rhizomucor miehei lipase fermentation by Aspergillus oryzaeProfiles of extracellular amino acids during RML fermentation between control group and SLs addition group. Nine representative amino acids including serine, threonine, glutamate, aspartate, histidine, leucine, isoleucine, valine and tyrosine were shown. The control groups were represented by black lines, and the SLs addition groups were represented by red linesBack to article page
