Abstract: | ABSTRACT: Cells of Lactobacillus delbrueckii subsp. lactis I were grown in several media to determine the most suitable medium for production of H2O2 during refrigerated storage. H2O2 was detected from cells that were resuspended in phosphate buffer containing variable amounts of glucose. Cells grown in MRS broth produced more H2O2 during refrigerated storage than those grown in LBS pr PTM. Cells grown in LBS produced more H2O2 then those grown in PTM. For both MRS and LBS, cells inoculated in phosphate buffer containing 0% glucose produced significantly more H2O2 than those containing 1% or 10% glucose. MRS medium appears to be the best medium for growing cells for the production of H2O2. |
