The world of baking is about to get a new helper.  This helper is a tiny organism called Bacillus cereus.  It is found in soil that is rich in organic matter and salt.  This tiny helper makes a special enzyme called alpha-amylase.  This enzyme has many uses in the food industry.  It is used in brewing, making animal feed, baking, and even in making fruit juice and starch syrups.  It is also used to break down starch into simpler sugars.

The Bacillus cereus strain GL2 was found in soil.  It was identified using genetic studies.  This strain produces a lot of alpha-amylase.  The best conditions for this strain to grow and produce alpha-amylase were found to be a pH of 6. 0, a temperature of 45°C, and an incubation time of 12 hours.  These conditions are important for getting the most out of this tiny helper.

The alpha-amylase produced by Bacillus cereus strain GL2 was purified.  This means that it was separated from other substances.  The purified enzyme was found to have a molecular weight of 58 kDa.  This is important for understanding how it works.  The optimal conditions for the enzyme to work were found to be a temperature of 50°C and a pH of 6. 0.  The enzyme was stable at 50°C, which means it can be used in processes that require high temperatures.

The purified alpha-amylase was added to flour during bread-making.  This improved the texture of the bread.  It made the bread less stiff and more flexible.  It also improved the overall quality of the bread.  This is because the enzyme helps to break down the starch in the flour, making it easier to work with and resulting in a better final product.  This tiny helper from the soil has the potential to revolutionize the baking industry.  It can help to make better bread with less effort.  It is a great example of how nature can provide solutions to everyday problems.  It is also a reminder that there is still much to learn about the tiny organisms that live in the soil around us.
