The construction of a colorimetric method for efficient sugar alcohol assay. a The interference test of the colorimetric method under different metabolites. b The standard curve of colorimetric method for d-arabitol detection. c Comparison of the colorimetric method with the HPLC method for sugar alcohol detection in different fermentation liquors. Data represent the average values of three independent experiments with deviation varying between 5 and 10% about the mean. d The construction of the P. anomala mutant library by ARTP and UV mutagenesis. The sugar alcohol production was preliminarily screened by colorimetric assay. The red
line represents the sugar alcohol yield of the initial strain P. anomala HP by the colorimetric method.
