WebApr 10, 2024 · Enzymatic degradation of pollutants by peroxidases is considered an effective substitute for the bioremediation of water resources. Hence, a novel peroxidase (POX ov) was obtained from the cell culture of Origanum vulgare with a good yield. The established cell culture had similar patterns of growth and POX ov production, reaching … WebThe changes in cell-wall peroxidase (POD) activity and H 2 O 2 level in roots of NaCl-stressed rice seedlings and their correlation with root growth were investigated. Increasing concentrations of NaCl from 50 to 150 m M progressively reduced root growth and increased ionically bound cell-wall POD activity.
WebThe cells extracted from the CNT-supplemented cotton cell suspension culture showed higher peroxidase activity (Figure 3A,B). Elevated peroxidase activity corresponds to tissue browning and stress response, as reported in the callus culture of Satureja khuzestanica supplemented with 500 µg/mL multi-walled CNTs [ 14 ]. WebPeroxidase stain. ( A) Large promyelocyte stains intensely (blue-black color) because of the abundant primary granules in cytoplasm (asterisk). Myelocytes and segmented neutrophil also stain but less intensely because of the decreasing concentration of primary granules. X.A.002 Acute Myelogenous Leukemia View Full Size Download Slide (.ppt)
