Nutrient Agar Plate Information

Nutrient agar contains 0.5 percent peptone, which is an enzymatic digest of animal protein. Peptone is the principal source of organic nitrogen for the growing bacteria. Nutrient agar also contains 0.3 percent beef extract, which contains water-soluble substances which aid in bacterial growth, such as vitamins, carbohydrates, organic nitrogen compounds and salts.

Structured silicon for revealing transient and integrated

18 Bacterial response to transient physical stress is critical to their homeostasis and survival in the dynamic natural environment. Because of the lack of biophysical tools capable of delivering precise and localized physical perturbations to a bacterial community, the underlying mechanism of microbial signal transduction has remained unexplored. Here, we developed multiscale and structured
