Fermentation Technique - an overview | ScienceDirect Topics

As the culture volume reaches near 70% of the reactor volume, the fermentation is stopped and product is harvested. This kind of system is applied to the production of chemicals that are not so toxic to the culture. An example of this process is bioconversion of glucose to 2,3-butanediol.

Radiation | What is Radiation? | ANSTO

Radiation. Radiation can be described as energy or particles from a source that travel through space or other mediums. Light, heat, and the microwaves and radio waves used for wireless communiions are all forms of radiation. Radiation includes particles and electromagnetic waves that are emitted by some materials and carry energy.
