This from an IT manager responsible for 36 programmers and QA staff at a billion-dollar company. She raised llamas in her spare time, so it was probably the truth. Even funnier, she didn't seem to think it was an unusual excuse! Sick kids and deceased relatives can't be avoided, but she mentioned it as if HR gave everyone three live llama birth days a year.
USES LYSINE DECARBOXYLASE BROTH is used to detect and differentiate Enterobacteria from other microorganisms, based on lysine decarboxylation. Gelatin peptone provides nitrogen, vitamins, minerals and amino acids essential for growth.Yeast extract is a source of vitamins, particularly of the B-group.
Each decarboxylase enzyme produced by an organism is specific to the amino acid on which it acts. Therefore, we test the ability of organisms to produce arginine decarboxylase, lysine decarboxylase, and ornithine decarboxylase using three different but very similar media.ecarboxylase broth contains nutrients, dextrose (a fermentable carbohydrate), pyridoxal (an enzyme cofactor for decarboxylase), and the pH indicators bromcresol purple and cresol red. Bromcresol purple turns purple at an alkaline pH and turns yellow at an acidic pH.
