This photograph depicts the colonial morphology displayed by Gram-negative Burkholderia thailandensis bacteria, which was grown on a medium of MacConkey agar, for a 24 hour time period, at a temperature of 42�C. See PHIL 12428, for a closer view of these bacterial colonies. Also, see both PHIL 12405 and 12406, for views of this bacterial specie, grown on the same medium, but at a lesser temperature (37�C), and at twice the amount of time (48hr). Note that PHIL 12410 and 12411 depict the same bacterial specie grown on the same media, and temperature (42�C), but a greater time period (48hr). Finally, take a look at PHIL 12419 and 12420 depicting colonial growth, on the same medium, and for the same amount of time (24hr), but at a lesser temperature (37�C).
