Is enterococcus faecalis positive or negative with the urea broth test?
It is urease positive .It possesses the enzymes urease which hydrolyses urea to form ammonia. As a result the pH of the medium used for detection of urease enzyme (Urea Broth) increases and shows bright pink colour, since phenol red is bright pink in alkaline conditions.
What is the name of medium used for rapid urease test for hpylori?
The medium used for the rapid urease test for H. pylori is called urea agar or urea broth. It contains urea as a substrate and a pH indicator to detect the presence of the enzyme urease produced by H. pylori.
What is the color of urease agar when inoculated with an urease negative organism?
The agar slant will remain the original color (yellow). However, most labs use the broth.Two media types are commonly used to detect urease activity. Christensen’s urea agar is used to detect urease activity in a variety of microorganisms. Stuart’s urea broth is used primarily for the differentiation of Proteus species.
What is the main advantage of the urea disk over both broth tubes and slants with respect to the detection or urease?
The main advantage of the urea disk test over broth tubes and slants for detecting urease activity is that it provides a rapid and visual color change result. Urea agar contains a pH indicator that changes color in response to urease activity, allowing for quick determination of urease production without the need for additional reagents or time-consuming procedures.
How do the pure broth culture differ?
Pure broth culture is a liquid media, used to propagate large numbers of microorganisms. Where as Slant cultures are semi solid media containing a solidifying agent (usually agar). Can be used in determining bacterial motility and in promoting anaerobic growth.
What kind of media must one use to determine chitinolytic activity?
Nutrient broth

What does SOC stand for in SOC broth?
It stands for 'Super Optimal Broth' for SOB media. The C stands for "catabolite-repression" which indicates that glucose has been added to the media. SOB is just SOC media with that addition.
Is tryptone broth differential or selective media?
Tryptone broth is neither differential nor selective media. It is a nutrient-rich medium used for the growth of a wide range of microorganisms.
What is the growth in broth media for proteus vulgaris?
hydrogen suifide i think
What media used to maintain microbes for long periods?
by subculture into non selective media such as soya broth or brain heart
What is the name of medium used for rapid urease test for hpylori?
The medium used for the rapid urease test for H. pylori is called urea agar or urea broth. It contains urea as a substrate and a pH indicator to detect the presence of the enzyme urease produced by H. pylori.
What is added to provide the bulk of nutrition in a complex media?
Beef broth is sometimes used.
What is a broth?
The culture which contain an organism (bacterial colony) which you are required to grow in a broth media that is a media lacking solidifying agent agar. A pure culture should not contain other bacterial or fungal cells in it except the required or cultured one

Christensen’s urea agar is used to detect urease activity in a variety of microorganisms. Stuart’s urea broth is used primarily for the differentiation of Proteus species.
What is the difference between a nutrient broth and media?
Nutrient broth is a liquid medium made of water, peptone, and beef extract used for growing bacteria, while media refers to any substance used to cultivate microorganisms in a lab setting, which can include solid or liquid forms with specific nutrients for microbial growth. In summary, nutrient broth is a type of media specifically designed for bacterial growth in liquid form.
What is a broth culture?
