Description

Fermenters are the vessels used to culture bacteria on a large scale. This is a sealed, sterilized vessel that preserves ideal conditions for microbial development. Fermenters are also utilized in the dairy, food and beverage, and pharmaceutical industries, among other things. Fermenters are the vessels used to culture bacteria on a large scale.

Fermenters, known as stirred-tank bioreactors, are tanks used to grow heterotrophic microalgae. Eukaryotic microalgae grow in a bioreactor with lower mixing intensity, while prokaryotic microalgae grow in a fermenter with higher mixing intensity. The cells are kept in suspension in the production medium in commercial-scale lactic acid bacterial operations by mixing with mechanical agitators or pumping the medium from the bottom to the top of the fermenter.
