Any series of hydroxyl comppounds derived from saturated hydrocarbons.
It is aclear liquid that has a strong smell.
A colourless, volatile, flameable liquid which is produced by fermentatiopn.
The test organism used here is known as Saccharomyces cervisae.
It is a type of yeast which is used in the production of alcohol.
It produces the enzyme invertase in both a cytoplasmic and a secreted form.
This yeast ferments a number of common substrates including sucrose and maltose.
The starter is prepared from the selected yeast isolated in pure culture.
A tube contaioning 10ml of of sterile wort is inoculated from pure culture of yeast.
After incubation for 25-30C for suitable time,culture in tube may be used to inoculate 200ml of sterile mash.
Aeration is useful in the preparation of starter.
Temperature – About 70C-80C
Time – 50 hours
The 90-95% alcohol is further purified, dehydrated or denatured to obtain different alcohols
