The Comprehensive Guide on Bioreactor

A bioreactor is a controlled vessel that supports biological reactions—often involving cells, enzymes, or microorganisms. It provides an environment with regulated temperature, pH, oxygen, and mixing, enabling processes like fermentation, cell culture, biofuel production, and wastewater treatment. Bioreactors emerged in the early 20th century to scale laboratory microbial processes for vaccines and industrial enzymes. Today, they are essential in pharmaceuticals, new food production, environmental systems, and research.
