“…E. coli O157:H7 was not enumerable from any of the 396 samples obtained during this study, so we could not determine whether HOBr treatment was effective in reducing the concentration of E. coli O157:H7 on hides. However, our laboratory recently demonstrated that spray treatment of inoculated beef carcass surfaces and beef hearts with the antimicrobial 1,3-dibromo-5,5-dimethylhydantion, which hydrolyzes to its active HOBr form in aqueous solution (23), was effective in reducing the levels of E. coli O157:H7 by 1.6 to 2.1 log CFU/100 cm 2 (16). Since we were able to demonstrate that HOBr reduced E. coli concentrations (ECC/100 cm 2 ) by 2.2 to 3.8 log (Table 1), it is reasonable to assume that enumerable E. coli O157:H7 concentrations, when present on hides, would be reduced by a similar level (4,18).…”

“…It has also been reported that hydantoin derived from imidazole, such as 1,3-dibromo-5,5-dimethylhydantoin, which is a widely used disinfectant in water treatment, can oxidize luminol to give CL emission [130].…”

“…However, there has been reported only a few examples of selective benzylic alcohol oxidations reactions in pure aqueous reaction conditions up to now [ 18 , 19 ]. 1,3-Dibromo-5,5-dimethyl hydatoin (DBDMH) has been -widely used as a green sterilizing disinfectant for various water purifications due to its very cheap and very low toxic properties [ 20 ]. DBDMH with a combination of chlorinated solvents has successfully been utilized in various bromination processes including benzylic bromination [ 21 ], dibromination of functionalized alkenes [ 22 ], oxidation of thiols [ 23 ], and bromination reactions of carboxylic acids [ 24 ].…”
