On YEMA medium containing bromothymol blue
(BTB), fast-growing strains of rhizobia produced colonies that were either yellow with creamy margins or yellowish or cream ranging from 2-5 mm in diameter within 3 days of incubation (Figure 2).

Caption: FIGURE 6: Kinetic for decomposition of bromothymol blue
with GZVINPs concentration of (a) 0.06 mM, (b) 0.12 mM, (c) 0.33 mM, (d) 0.5 mM, and (e) 0.66 mM.
Isolates were tested on different dyes like Congo red and Bromothymol blue
(BTB) in the YMA and stained for its gram reaction.

Pyruvate acidification was performed in 1% pyruvate broth with bromothymol blue
as an indicator.
Screening for acid producing ability was determined by using the bromothymol blue
indicator along with nutrient broth.
Three different basic strong indicators were used: bromothymol blue
(7.2 < H < 9.3), phenolphthalein (9.3 < H < 15) and 2.4-dinitroaniline (15 < H < 18.4).
The photocatalytic activities of the Ti[O.sub.2] films were evaluated by the photocatalytic decomposition of an aqueous solution of bromothymol blue
(BTB) in a recirculation type annular tube photoreactor.
Identification of Cryptococcus gattii by use of L-canavanine glycine bromothymol blue
medium and DNA sequencing.
The mixture was then filtered and the filtrate was titrated against 0.1 N NaOH with 4-7 drops of bromothymol blue
as an indicator.
* If available, you can use Bromothymol blue
(available in the aquarium section of most pet stores) instead of cabbage juice.
Our protocol uses a tube-in-tube design with six sugar substrates at the same molar concentration, bromothymol blue
as the indicator and yeast as the subject organism.
Ten milligram methyl red (MR) and 30 mg bromothymol blue
(BTR) were dissolved in 15 mL of 95% (v/v) ethanol, then brought to a final volume of 20 mL by adding 5 mL of distilled water.
