This video describes the role of the fermentation process in the creation of biological products and illustrates commercial-scale fermentation at a cellular level. Included are descriptions of types of fermentation (intracellular, extracellular), types of cells (aerobic, anaerobic), and cell nutrition (media components). The program follows the production of a batch of Green Fluorescent Protein (GFP) from preparation through harvesting, including growth of seed stock, scaling up, and life cycle growth pattern phases (lag, exponential/log, stationary, death). Featured throughout is the monitoring of various production process parameters, including time, temperature, pressure, pH, agitation, etc.

This video is the second in a series of three videos depicting the major stages of industrial-scale bioprocessing: fermentation, separation/recovery, and purification. This video describes the process by which a biological product-in this case, molecules of Green Fluorescent Protein (GFP)-is recovered from host e coli cells. The steps of this process are, in very basic terms: (1) separation of cell solids from the broth, (2) disruption of those host cells to release the product contained in them, and (3) isolation of the product through removal of cell debris and other impurities. Tools used to perform these steps include centrifuges, cell disrupters and microfilters.

This video is the third in a series of three videos depicting the major stages of industrial-scale fermentation: fermentation, separation/recovery, and purification. This program describes the process by which a biological product-in this case, a pure, concentrated solution of Green Fluorescent Protein (GFP)-is derived from clarified lysate. This is accomplished through multiple variations of two basic procedures: chromatography and filtration.

Fermentation requires rigorous monitoring and control of the environment within the bioreactor. The reactor is equipped with a water jacket to regulate temperature, and integrated sensors to monitor key factors, such as dissolved oxygen, pH, internal temperature, water-jacket temperature and vessel pressure. The reactor also has an agitator, dedicated ports for adding seed stock and media ingredients, separate ports for acid and base supplement, air filters for supply and exhaust, and valves for drawing samples and for harvesting. Most fermentation and monitoring functions can be managed from the bioreactor's dedicated process controller.

Paul Andersen differentiates between biotic and abiotic factors. He explains how both abiotic and biotic factors can affect organisms at the level of the cell, the population and even the ecosystem. The complexities of biofilms, predator-prey relationships, and food webs are given as illustrative examples.
