Norris Glucose Nitrogen Free Medium

 Microorganisms need specific chemical and physical conditions to grow in order to survive both in the laboratory and in the natural world. Understanding these conditions allows us to characterize isolates and distinguish different types of bacteria. In practice, such knowledge can be used to control the growth of microorganisms.

Norris Glucose Nitrogen Free Medium is used to cultivate chemoheterotrophic bacteria that can fix atmospheric nitrogen. Chemoorganotrophs are organisms that are generally organotrophic. These organisms can get their carbon and energy from a variety of organic compounds. A common sugar used is glucose. ATP is generated by either substrate-level or oxidative phosphorylation. The presence of calcium carbonate results in an opalescent solution with a white precipitate in the prepared medium.



The Norris Glucose Nitrogen Free Medium consists of glucose that serves as the carbon source. The presence of sodium molybdate in the medium promotes nitrogen fixation. Different salts in the medium serve as buffers as well as essential ions for the chemoheterotrophic bacteria.

Bacillus coagulans Isolation Using Glucose Yeast Extract BC Agar Medium

Image
  Bacillus coagulans is a lactic acid-producing bacterial species. It is a type of probiotic. Probiotics are live microorganisms that are intended to provide health benefits when consumed in the body. Probiotic organisms include Lactobacillus, Bifidobacterium, Enterococcus, Bacillus, and Streptococcus. Bacillus coagulans is a probiotic that produces lactic acid, but it is not the same as Lactobacillus. Unlike Lactobacillus and many other probiotics, it can produce spores during its reproductive life cycle. This ability allows Bacillus coagulans to go dormant during harsh conditions that would otherwise kill off other probiotics. As a result, this bacterial strain is particularly robust. It can withstand harsh environments, such as high levels of acid in the stomach. This may make Bacillus coagulans particularly effective at treating stomach upset and other ailments. Spore forming Bacillus coagulans strains are used as probiotics for antibiotic-treated patients in some countri...

Triple Sugar Saline Iron Agar

  In 1940, Sulkin, Willett, and Hajna described a triple-sugar ferrous sulphate medium for the identification of enteric bacteria. Triple Sugar Iron (TSI) Agar is used for the presumptive identification of Enterobacteriaceae based on the fermentation of carbohydrates and the production of gas and H 2 S. Triple Sugar Iron Agar contains three carbohydrates: glucose (dextrose), lactose, and sucrose. Triple Sugar Iron Agar is a differential medium that contains lactose, sucrose, a small amount of glucose (dextrose), ferrous sulphate, and the pH indicator phenol red. If an organism can ferment any of the three sugars present in the medium, the medium will turn yellow. If an organism can only ferment dextrose, the organism consumes a small amount of dextrose in the medium within the first ten hours of incubation. After that time, the reaction that produced acid reverses in the aerobic areas of the slant, and the medium in those areas turns red, indicating alkaline conditions.  T...

Tryptone Soya Agar: An USP-Compliant Media

Image
  Tryptone Soya Agar, also known as Soyabean Casein Digest Agar, is a popular medium for the growth of a wide range of organisms, including pathogenic bacteria such as Neisseria, Listeria, and Brucella. The medium with blood addition provides perfectly defined haemolysis zones, while the sodium chloride content prevents erythrocyte lysis. It has been widely used in the pharmaceutical industry to create antigens, toxins, and other substances. Because of its simple and inhibitor-free composition, it is suitable for detecting antimicrobial agents in food and other products. Various pharmacopoeias recommend Tryptone Soya Agar as a sterility testing medium. Tryptone Soya Agar is USP-compliant and used in microbial limit testing and antimicrobial preservative testing.  It is also used in the pharmaceutical industry to perform various tests such as environmental monitoring, maintenance of stock cultures, etc. Principle Gunn et al. used this medium to grow fastidious organisms and...
