Document Summary
Blue in acid-fast stain, so not acid-fast; gram negative. Cemo: single bacillus; is a lactose fermenter so on. Emb agar produces a lot of acid so produces blackened colony with green metallic sheen. Como: purple and white, round, smooth, convex, opaque, dull. Temperature range is -37 degrees celsius and dies in. 60 degrees celsius+; optimum ph growth is 7 (mesophile); uv range is. 0-0. 5 minutes and begins to die at 1 minute (completely dead by 5); grows at to 0. 5% [nacl] (not necessarily halotolerant) Grows at 0. 5-10% [nacl] but grows best at 0. 5% (halotolerant) 100 degrees celsius; withstands up to 5 minutes of uv radiation (endospore) Standard for population count with 10^8 cfu/ml; a coliform found in large numbers in sewage water survives longer than intestinal pathogens and is used as an indicator organism for fecal contamination. Not motile from motility medium deep; soil bacteria. Produces little acid from lactose fermentation so creates fish-eye colony on.
