What is Thioglycolate medium used for?
Fluid Thioglycollate Medium is a general purpose liquid enrichment medium used in qualitative procedures for the sterility test and for the isolation and cultivation of aerobes, anaerobes and microaerophiles that are not excessively fastidious.
Which bacteria would grow at the bottom of a thioglycolate tube?
For example, obligately anaerobic Clostridium species will be seen growing only in the bottom of the test tube. Thioglycolate broth is also used to recruit macrophages to the peritoneal cavity of mice when injected intraperitoneally.
What is the purpose of thioglycollate in thioglycollate media?
Thioglycolate broth is a multipurpose, enriched, differential medium used primarily to determine the oxygen requirements of microorganisms. It acts as an enrichment broth which is most frequently used in diagnostic bacteriology….Composition of Thioglycollate Broth.
| Ingredients | Gms/liter |
|---|---|
| Sodium thioglycollate | 0.5 |
What type of medium is thioglycollate?
Thioglycollate Broth (THIO) is an enriched nonselective liquid medium used for the growth of microaerophilic and anaerobic bacteria, including fastidious organisms, from clinical specimens.
What is thioglycolate?
Thioglycolic Acid is a colorless liquid with an unpleasant odor (like rotten eggs). It is used in making hair dressing solutions, pharmaceuticals and chemicals.
How does thioglycollate work?
Sodium Thioglycollate: Sodium Thioglycollate is a reducing agent which maintains a low oxygen tension by removing molecular oxygen from the environment i.e., it creates anaerobic conditions when it reduces molecular oxygen to water.
Which microorganism shows even growth throughout thioglycollate broth?
A. Gram-negative, facultatively anaerobic bacilli (i.e., those that can grow in the presence or absence of oxygen) generally produce diffuse, even growth throughout the broth.
What is the pH of thioglycolic acid?
pH 1–1.5
From thioglycolic acid medium (pH 1–1.5), Mo is retained in the column while V passes into the eluate.
What is Thioglycolate?
What are the 3 types of oxygen requirements in bacteria?
Summary
| Classification | Characteristics |
|---|---|
| Obligate aerobes | Require oxygen, Have no fermentative pathways. Generally produce superoxide dismutase |
| Microaerophilic | Requires low but not full oxygen tension |
| Facultative anaerobes | Will respire aerobically until oxygen is depleted and then ferment or respire anaerobically |
What is the role of thioglycolic acid?
Thioglycolic acid is used as reagent for the preparation of different chemicals such as pesticides, herbicide, or for some polythiols and thio-esters.
Why thioglycolic acid is used in limit test of iron?
Thioglycolic acid is also called citric acid. In the limit test of iron, iron reacts with citric acid in ammoniacal solution to form pink-reddish purple coloured iron thioglycolate. In this reaction, citric acid acts as a chelating agent. It binds the iron to form a soluble complex.
What are the 5 oxygen classifications for bacteria?
Terms in this set (5)
- Strict aerobes. Require free oxegen to grow, at least the 20% found in air.
- Strict/obligate anaerobes. Will not grow or may be killed by the presence of oxygen.
- Microaerophilic. Grow best in the presence of low levels of oxygen.
- Facultative aerobe/anaerobe.
- Aerotolerant.
Why is thioglycolic acid used?
General Information. Thioglycolic acid is a colorless liquid with a strong, typical mercaptan disagreeable odor (although olfactory fatigue may occur) which is used in cosmetic formulations including permanent wave solutions and depilatories, in pharmaceutical manufacture, and as a stabilizer for vinyl plastics.
What are the 6 conditions for bacterial growth?
FATTOM is an acronym used to describe the conditions necessary for bacterial growth: Food, acidity, time, temperature, oxygen, and moisture. Foods provide a perfect environment for bacterial growth, due to their provision of nutrients, energy, and other components needed by the bacteria.
