Abstract:
This project involved the evaluation of a biosafety level 1 alternative to Proteus vulgaris as a positive control for the production of hydrogen sulfide. We determined that Citrobacter freundii could serve as an excellent substitute for P. vulgaris, and that lead acetate strips used in conjunction with triple sugar iron media allows for consistent results following evaluation after up to one week.
