Abstract :

This research was aimed to investigate the colour differences between Escherichia coli and Pseudomonas aeruginosa colonies in artificial medium that was made from beef extract, mung beans juice, citrate and bromthymol blue. The medium was made by mixing 1.6% agar base, 0.8% beefextract, 20% mung beans juice, 0.2% sodium citrate, 2% lactose, and 8% of bromthymol blue solution0.1% into 1000 ml aquadest. The isolate of Escherichia coli and Pseudomonas aeruginosa wereinoculated onto the media with five repetitions. As control, Escherichia coli and Pseudomonasa eruginosa were inoculated onto the media that were made from beef extract and mung beans juice, without citrate and bromthymol blue. The whole media were incubated at 37o C for 24 hours. The result showed that the colour of Escherichia coli colonies can be distinguished with Pseudomonas aeruginosa’s. Escherichia coli colonies appeared colorless, wet, shiny and the surrounding medium remained yellow. Pseudomonas aeruginosa colonies appeared bluish-white, with thick and mucoid form and the surrounding medium changed its colour to green. Based on the result, the artificial medium that was made from beef extract, mung beans juice, citrate and bromthymol blue can be used in Microbiology Laboratories as a differential medium to distinguish bacteria whether they utilize citrate as energy and carbon source or not.
