The pen may be mightier than the sword, but a magic wand is more powerful than either, or at least according to this year's Forbes' list of the world's richest celebrities. Harry Potter author JK Rowling earned more than any other celebrity, according to the annual Celebrity 100 list, taking home $300m (Â£150m) last year. There were other strong British performances from Keira Knightley, announced as the world's second best paid female actor, Potter actor Daniel Radcliffe and David Beckham.
A facultative anaerobe is, simply speaking, an organism which possesses the ability to survive in an environment containing oxygen while growing even more efficiently in an environment without oxygen. Facultative anaerobes can optionally function without oxygen by two main mechanisms; fermentation and alternate terminal electron acceptors. In fermentation, glycolysis is performed and pyruvate is converted to a fermentation product, reducing NAD+ back to NADH. (Note that there are likely many variations on this).
Fermentation. Fermentation is the heart of the brewing process. During fermentation, wort created from raw materials is converted to beer by yeast. Fermentation is usually divided into three stages: primary, secondary, and conditioning (or lagering).Fermentation is when yeast produce all of the alcohol and aroma and flavor compounds found in beer.Manipulation of temperature, oxygen levels, and pitch rate as well as yeast strain selection will all dramatically affect the production of aroma and flavor compounds produced during fermentation.ermentation is when yeast produce all of the alcohol and aroma and flavor compounds found in beer.
