Batch and Continuous Bioreactors
0 Views •
2023
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...

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...

We present a protocol for identifying and quantifying the components in mixtures of species possessing similar proteins. Mass spectrometry detects peptides for identification, and gives relative quantitation by ratios of peak areas. As a tool food for fraud detection, the method can detect 1% horse in beef.
FAQs
Authentication depends on agreement among several evidence streams rather than a label alone. Lot records and labeling establish the expected identity, while chain-of-custody information documents handling and movement. Representative-sample testing then compares the batch with defined specifications through identity assays, molecular analysis, or biochemical characterization. Together, these checks can reveal mix-ups, inconsistency, or contamination before use.
A representative sample connects laboratory testing to the batch as a whole. If the sample does not reflect the material being assessed, an identity or composition result may not support a reliable batch decision. Using representative samples alongside records and defined specifications allows testing to provide evidence that the biological product matches its approved composition and quality requirements.
These approaches provide different ways to compare a batch with its defined specifications. Identity assays can support confirmation of what the material is, while molecular analysis and biochemical characterization provide additional analytical evidence about its biological composition. Their use helps strengthen authentication when documentation and labeling must be evaluated alongside laboratory findings.
A practical workflow starts by reviewing lot records and labeling, then examining chain-of-custody information to follow the batch through handling and movement. A representative sample is selected for testing with an identity assay, molecular analysis, or biochemical characterization. The resulting findings are compared with approved composition and quality specifications to support a suitability assessment.
The approach applies across several types of biological products, including vaccines, therapeutics, diagnostic materials, and cell-culture reagents. These products may support manufacturing, testing, experiments, or clinical use, so accurate identification and consistent composition matter. Authentication strengthens confidence that the material being used corresponds to the intended product and meets its stated requirements.
For experimental and clinical materials, authentication provides evidence that a batch is suitable for its intended application. Traceability helps connect the material to its records and handling history, while testing checks its identity and composition against defined requirements. This combination supports more reliable use of biological products and helps identify mix-ups or contamination that could affect results or applications.
