Aspergillus oryzae is a mold used in East Asia to saccharify rice, sweet potato, and barley in the making of alcoholic beverages such as sake and shōchū, and also to ferment soybeans for making soy sauce and miso. It is one of the different koji molds ニホンコウジカビ (日本麹黴) (Japanese: nihon kōji kabi) used for food fermentation.
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 ...
Aspergillus oryzae and A. sojae are used in East Asian cuisine in the production of sake, soy sauce and other fermented food products. Aspergillus terreus is used in the production of organic acids but can also cause opportunistic infections in humans.

A bacterial reference chart is used to determine the number of bacteria in the sample. Appropriate treatment is applied to the water source once abnormal levels of bacterial activity are noticed. Once water treatment is effective the bacterial count produced by the dip slide test should be low, approximately <10 4. [2] Dip slides are normally ...
A study found that more than 20% of reusable water bottles contained coliform bacteria, or fecal matter. Here's the best way to clean that bottle and avoid harmful germs. Like many people, Carl ...
Indicator bacteria can be cultured on media which are specifically formulated to allow the growth of the species of interest and inhibit growth of other organisms. Typically, environmental water samples are filtered through membranes with small pore sizes and then the membrane is placed onto a selective agar.
The presence of bacteria commonly found in human feces, termed coliform bacteria (e.g. E. coli), in surface water is a common indicator of faecal contamination. The means by which pathogens found in fecal matter can enter recreational bodies of water include, but are not limited to, sewage, septic systems, urban runoff , coastal recreational ...
