Pseudomonas putida CPl formed clump of cells Dexamethasone sodium phosphate powder was
when grown on all the three kinds of irradiated at different does (0.5 to 10.0 Mrad) and
monochlorophenol isomers. Ethylenediaminetetraacetic subsequent changes were observed. A dose of 1.0
acid (EDTA) caused no dispersion of flocs. High Mrad was found to be enough to sterilize the
power (100 W output) sonication caused dispersion powder, which had an initial microbial count of 3.0

of the floc and it also caused cell lysis. Sonication x 10 cfu/g. No significant change in colour and
at low power (50 W output) for 30 sec caused pH was observed in powdered dexamethasone
dispersion and no cell lysis. Sodium sodium phosphate with the increase in radiation
tripolyphosphate had no significant effect on dose. The spectrophotometric measurement and
dispersion of the flocs. Monitoring growth of the high performance liquid chromatography (HPLC)
organism by a direct microscopic count technique analysis of irradiated dexamethasone sodium
was found to be more representative than other phosphate showed no marked loss of potency even
methods including optical density measurements; up to the dose of 10.0 Mrad. No degradation
dry weight measurements and the plate count product and extra peak was found at a dose of 10.0
