A SCOBY used for brewing kombucha. Kombucha co-culture with SCOBY biofilm. Symbiotic culture of bacteria and yeast (SCOBY) is a culinary symbiotic fermentation culture consisting of lactic acid bacteria (LAB), acetic acid bacteria (AAB), and yeast which arises in the preparation of sour foods and beverages such as kombucha.

Kombucha is thought to have originated in China, where the drink is traditional. [3] [4] By the early 20th century it spread to Russia, then other parts of Eastern Europe and Germany. [5] Kombucha is now homebrewed globally, and also bottled and sold commercially. [1] The global kombucha market was worth approximately US$1.7 billion as of 2019.
The lactic acid bacteria (LAB) are either rod-shaped (), or spherical (), and are characterized by an increased tolerance to acidity (low pH range).This aspect helps LAB to outcompete other bacteria in a natural fermentation, as they can withstand the increased acidity from organic acid production (e.g., lactic acid).
A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology .
As an eukaryote, S. cerevisiae shares the complex internal cell structure of plants and animals without the high percentage of non-coding DNA that can confound research in higher eukaryotes. S. cerevisiae research is a strong economic driver, at least initially, as a result of its established use in industry.
Microbial genetics can focus on Charles Darwin's work and scientists have continued to study his work and theories by the use of microbes. [7] Specifically, Darwin's theory of natural selection is a source used.
Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
AQC is achieved through laboratory control of analytical performance. Initial control of the complete system can be achieved through specification of laboratory services, instrumentation, glassware, reagents, solvents, and gases. However, evaluation of daily performance must be documented to ensure continual production of valid data.
