A synchronous or synchronized culture is a microbiological culture or a cell culture that contains cells that are all in the same growth stage. [ 1 ] [ 2 ] As numerous factors influence the cell cycle (some of them stochastic ) normal cultures have cells in all stages of the cell cycle .
A company's place on the matrix depends on two dimensions – the process structure/process lifecycle and the product structure/product lifecycles. [1] The process structure/process lifecycle is composed of the process choice (job shop, batch, assembly line, and continuous flow) and the process structure (jumbled flow, disconnected line flow, connected line flow and continuous flow). [1]
The bacterial culture is incubated in a closed vessel with a single batch of medium. In some experimental regimes, some of the bacterial culture is periodically removed and added to fresh sterile medium. In the extreme case, this leads to the continual renewal of the nutrients. This is a chemostat, also known as continuous culture. It is ...
Continuous-flow manufacturing, or repetitive-flow manufacturing, is an approach to discrete manufacturing that contrasts with batch production.It is associated with a just-in-time and kanban production approach, and calls for an ongoing examination and improvement efforts which ultimately requires integration of all elements of the production system.
Another important feature of chemostats and other continuous culture systems is that they are well-mixed so that environmental conditions are homogenous or uniform and microorganisms are randomly dispersed and encounter each other randomly. Therefore, competition and other interactions in the chemostat are global, in contrast to biofilms.
A simple example involves the bacterium Escherichia coli (E. coli), the best understood bacterium. The bacterium is grown on a growth media containing two types of sugars, one of which is easier to metabolize than the other (for example glucose and lactose). First, the bacterium will metabolize all the glucose, and grow at a higher speed.
Continuous production is a flow production method used to manufacture, produce, or process materials without interruption.Continuous production is called a continuous process or a continuous flow process because the materials, either dry bulk or fluids that are being processed are continuously in motion, undergoing chemical reactions or subject to mechanical or heat treatment.
Fed-batch reactor symbol. Fed-batch culture is, in the broadest sense, defined as an operational technique in biotechnological processes where one or more nutrients (substrates) are fed (supplied) to the bioreactor during cultivation and in which the product(s) remain in the bioreactor until the end of the run.
