Colony characteristics

• White smooth and non-photochromogenic colonies
  Colony (biology)
  In biology, a colony reference to several individual organisms of the same species living closely together, usually for mutual benefit, such as stronger defense or the ability to attack bigger prey. Some insects live only in colonies...

Physiology

• Fast growth at 28°C and 37°C within 3 days, no growth at 42°C.
• Resistant to isoniazid
  Isoniazid
  Isoniazid , also known as isonicotinylhydrazine , is an organic compound that is the first-line antituberculosis medication in prevention and treatment. It was first discovered in 1912, and later in 1951 it was found to be effective against tuberculosis by inhibiting its mycolic acid...
