phenol red act as the pH indicator. As the substrate urea is split into products, the presence of ammonia caused alkaline environment that cause the phenol red to turn to deep pink. Useful to test Proteus vulgaris.
flasks, broth, time, location, time, temperature.
Cytosol is the non-structured part of the cell's cytoplasm. An analogy could be soup. Soup consists of broth plus pieces of vegetables, noodles, pieces of chicken, etc. Cytosol is like the broth, and the organelles are like the added pieces.
The independent variable is the one that the experimenter changes, and the dependent variable is the response. For example - if you were doing an experiment about the affect of temperature on growth rates: Temperature = Independent variable Growth = Dependent variable
I would say that broth is a liquid, as it flows freely unless it is kept in a confined area. It isn't a gas as it cannot diffuse or change volume and isn't a solid unless frozen. the steam from hot broth could be a gas though...
The test is considered qualitative because you are looking for a negative or a positive test . A example is looking for change of colour in the brilliant green bile broth tubes.

Negative for both. Pseudomonas does not ferment sugars.
In our lab we use LB agar, LB broth, and 2XYT broth.
broth
Beef broth provides nutrients and essential components such as amino acids, vitamins, and minerals that support the growth of microorganisms in a culture medium. It also helps maintain the pH balance and serves as a source of carbon and energy for microbial metabolism.
KCN broth is a complex medium typically made from organic ingredients like meat extracts or peptones. It is not a synthetic medium composed of defined chemicals.
LB stands for Lysogeny Broth, which is a nutrient-rich medium used for cultivating bacteria. LB agar is a solidified form of this medium, containing agar to solidify the liquid broth for bacterial growth.
broth medium
Bacillus subtilis is grown on nutrient agar or in nutrient broth. The preferred medium is M9 with glucose.
use glucose phosphate broth , inoculate the organism in that broth and incubate at 37 degree celsius for 24 hrs.
