Aspergillus sp. growing in potato dextrose agar Potato dextrose agar (BAM Media M127) and potato dextrose broth are common microbiological growth media made from potato infusion and dextrose. Potato dextrose agar (abbreviated "PDA") is the most widely used medium for growing fungi and bacteria. PDA has the capability to culture various bacteria and fungi found in the soil. This agar can be ...
The fungus can grow in a range of environmental conditions; it can grow at temperatures ranging from 6 to 47 °C. [12] As a mesophile, [13] its optimal temperature range is 35-37 °C. [11] It can tolerate pH ranging from 1.5 to 9.8. [12] A. niger is xerophilic, meaning it can grow and reproduce in environments with very little water.
The chromatic transition from blue to red phase of PDA is caused by the electronic structure of PDAs' backbone which is featured by the alternative carbon double bond and carbon triple bond. Upon exposure to the external stimuli such as thermal, chemical and mechanical stimulus, the conjugation effect will endow the chromatic properties to this ...
It would be acceptable to consider that raw materials used to manufacture pharmaceutical products can vary in their attributes e.g. moisture content, crystal structure etc. It would also be acceptable to consider that manufacturing equipment does not always operate in exactly the same fashion due to the inherent tolerance of the equipment and ...
Plate count agar (PCA), also called standard methods agar (SMA), is a microbiological growth medium commonly used to assess or to monitor "total" or viable bacterial growth of a sample.
p-Phenylenediamine (PPD) is an organic compound with the formula C 6 H 4 (NH 2) 2.This derivative of aniline is a white solid, but samples can darken due to air oxidation. [1] It is mainly used as a component of engineering polymers and composites like kevlar.
You’ve seen them—and their hands—everywhere: Kourtney Kardashian and Travis Barker (aka ‘Kravis’). From watching the couple fondle each other at family get-togethers to tongue-touching ...
The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.
