Batch and Continuous Bioreactors

Bioreactors are used to grow organisms in large volumes, thereby enabling the production of mass quantities of the target product. These reactors can be batch reactors, which contain all of the components needed for cell growth, or continuous reactors, which have inlet and outlet ports allowing for the addition of fresh growth media and the removal of cell waste. This video presents batch and continuous reactors and demonstrates the use of bioreactors to grow bacteria in the laboratory.

Fed-Batch Culture

2026
Fed-batch culture is a widely used bioprocessing strategy combining aspects of batch culture with controlled substrate feeding to optimize cell growth and product formation. In this semi-closed system, nutrients are strategically added during fermentation, while the accumulated products and biomass remain within the bioreactor until the end of the operation. This controlled addition of substrates allows for better management of growth kinetics, nutrient limitation, and metabolite...

Batch vs Continuous Culture

Fermentation is a foundational biotechnological process used to produce pharmaceuticals, biofuels, enzymes, and food additives. Among industrial strategies, batch and continuous fermentation are the two most widely applied. Although both rely on microbial conversion of substrates into desired products, they differ markedly in operation, productivity, and suitability for specific applications.Batch fermentation occurs in a closed system in which nutrient media and inoculum are added at the...
FAQs
Shear separates material layers and helps break up agglomerates, while bulk movement transports larger portions of the contents through the vessel. Working together, these motions distribute components more evenly than either mechanism alone. Their combined effect supports uniform composition, particularly when the mixture contains materials that differ in particle size, viscosity, or moisture content.
Mixer geometry determines how rotating blades, paddles, or impellers move material within the vessel. Engineers therefore match the mixer design to material properties and the required degree of blending. A suitable geometry promotes effective distribution and agglomerate breakup, whereas an unsuitable arrangement may not provide the movement needed for consistent composition.
Defined mixing time and rotational speed are central operating conditions because they determine how long and how intensely the materials experience blade, paddle, or impeller action. Controlling these variables helps produce repeatable cycles and consistent product quality. Engineers also consider the formulation and material properties when establishing appropriate conditions for each batch.
Rotating mixing elements apply shear that helps break apart agglomerates, while bulk movement redistributes the released material throughout the vessel. This combination reduces localized concentrations and supports a more uniform mixture. The result is especially important when precise formulation or consistent composition is required, as in controlled production of engineered and formulated products.
A typical workflow begins by measuring the required quantities of each component and placing them in the contained vessel. Engineers then select mixer geometry and define operating conditions, including mixing time and speed, according to the materials being processed. The rotating elements blend the batch until the process supports the intended uniformity and repeatable formulation.
Batch mixers are useful when production requires measured formulations, controlled cycles, and the ability to adjust conditions for different materials or products. Their adaptability supports repeatable processing across formulations with varying viscosity, particle size, or moisture content. This makes them relevant to production settings where precise composition and consistent quality matter.
Batch mixing supports concrete, polymers, pharmaceuticals, food products, and chemicals. In these areas, the process helps combine measured components under defined conditions so products can achieve consistent composition and repeatable quality. Engineering decisions about mixer geometry, mixing time, speed, and material properties help adapt the same general approach to different production requirements.
