I want to isolate sulphur oxidizing bacteria from environment. I try using bromo phenol blue as colour indicator if there is any suplhur oxidizing bacteria in my sample.
Is there any colours indicator for qualtative screening of Sulphur Oxidizing Bacteria?
Thank You
There are several indicators used for screening of SOB:
1. Bromo phenol blue (BPB) (0.0025 g)

2. 0.1% thymol blue solution

p.s. You don’t need to use additional color indicator if you are using some of the ready-to-use culture media. It is already included.
e.g. SOB Broth:
