Tag: nutrient broth

Hi all,
Restreaked a few nutrient agar plates, hoping to find pure colonies of the target bacterial cultures that were incubating. One of the cultures didnt need to be streaked, as it was a confirmed bacteria, chromobacterium violeceum. Confirmed as it produces low, convex colonies with a dark purple/metallic sheen (violacein production). This culture, using aseptic techniques, was innoculated into nutrient broth and incubated at 30C for a coulpe of days. Then it will be made into stabs and slopes for long term storage. Researching more on selective agars to confirm more of the cultures on my lab bench. Made up more nutrient agar plates, counted colonies from Sharons Brayford pool project, cleaned lab – quite theraputic. Can’t wait to see what tomorrow brings.
