Strategies to decolorize high concentrations of methyl orange using growing cells of lactobacillus casei TISTR 1500
Batch, fed-batch, and continuous fermentation was used in the processing of methyl orange decolorization using growing cells of Lactobacillus casei TISTR 1500. This report presents the optimal conditions for methyl orange decolorization by the strain TISTR 1500 in modified MRS via a central composit...
