Are there any pH indicators which can kill bacteria?

I'm thinking of using bromocresol purple to identify lactic acid bacteria colonies but was wondering whether there are any I should definitely avoid as it could kill or inhibit the bacteria in any way?

Thank you :)

Some dyes like rose bengal are used functionally in selective media but I'm not aware of selective dyes used as pH indicators. I'd sure validate whatever you use.
