General description

Nutrient Broth is a general-purpose fluid media containing yeast extract, peptone, sodium chloride and other basic nutritional requirements for the growth of a wide variety of microbes that don’t require specific nutrients. It is used in the routine cultivation of microorganisms from both clinical and non-clinical samples. Addition of different biological fluids like blood, serum, egg yolk etc. can make it suitable for cultivation of more fastidious microbes.

Application

•Nutrient Broth No. 1 is used for the routine cultivation of microorganisms not requiring specific nutritional requirements
•It is also used for the enumeration and enrichment of bacteria.
•Nutrient Broth No 1 can be used as a base for preparing special culture media.

Preparation Note

Dissolve 25 g in 1 litre distilled water and fill into tubes. Sterilize by autoclaving at 121°C for 15 minutes.

Footnote

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.

Methylotrophic bacteria use methanol and related C1 compounds as carbon and energy sources. Methanol dehydrogenases are essential for methanol oxidation, while lanthanides are important cofactors of many pyrroloquinoline quinone-dependent methanol dehydrogenases and related alcohol dehydrogenases.

Estrogenic chemicals are widespread environmental contaminants associated with diverse health and ecological effects. During early vertebrate development, estrogen receptor signaling is critical for many different physiologic responses, including nervous system function. Recently, host-associated microbiota have been shown to influence neurodevelopment.
