Flashcards in Biotechnology: Fermenters Deck (4)
What is fermentation?
The process by which microorgansims take in food from the environment as an energy source and excrete waste substances, changing substances in the surrounding medium over time
Give the word equation for the fermentation of sugar, using yeast
Sugar= ethanol + Carbon dioxide
What is a fermenter?
A controlled environment that provides ideal conditions for microorgansims to live, feed and reproduce
What are the conditions of a fermenter?
Sterile conditions, nutrients, an optimum temperature, the correct pH level, oxygenation, agitation (stirring)
