I'm doing isolation of endophytic PGP from plant root and I've read about journal that use bromothymol blue (BTB) as indicator, is there any other option other than using BTB?

Bromo thymol blue screening is useful to consider a PGPR bacteria as a slow growing or fast growing. ARA is suitable to measure nitrogenase activity. Correct me if I am wrong..

@all, what about growing a potential nitrogen fixer on Glucose nitrogen-free medium (GNFM) and BTB as an indicator for nitrogen-fixation?
