Imagine a vessel where you are growing E. coli and after some time it reaches the highest density it can so it stops growing. Take half of that culture and put it into another vessel so now you have two vessels. Dilute them to the original volume with fresh nutrients etc. Those cultures will start to grown once more. Keep doing this over and over or however many times you need.

It is a way of getting more biomass from the original culture.

What is the real degree of fermentation in this particular batch of wine?

The real degree of fermentation in this batch of wine is the actual amount of sugar that has been converted into alcohol during the fermentation process.


In batch fermentation substrate is added continuously and the product is siphoned off throughout the run?

In batch fermentation, substrate is added all at once at the beginning of the process, and no more is added during the run. The product is generally not siphoned off during the fermentation process but is harvested once the fermentation is complete.


What the different between fed batch fermentation and batch fermentation?

batch fermentation : fermenter is filled ONCE until its full, (no more substrate added through reaction), no product harvesting tale place during process. Product is harvested after the completion of the process.fed batch : fermenter is only partly filled (certain amount of substrate is added throughout the reaction), 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.


What is the difference between batch fermentation and continuous fermentation?

You didn't give a context, but in an application like credit card processing a batch process collects a number of transactions into a batch and then sends them all at once at a predetermined time or as part of a manual process. A continuous process would process the cards as they were presented. In reality there is a mix in CC processing where a quick check is made on validity of card when presented and complete processing in a batch. In some transmission applications data is first collected and then "burst" out at a later time or after all the data is collected. This is analogous to a batch transmission.


Builds in muscles due to fermentation?

Lactic Acid is produced during extended muscle contraction by fermentation.


Which is better batch or continuous fermentation?

The choice between batch and continuous fermentation depends on the specific goals of the process. Batch fermentation is typically easier to manage and allows for more control over the fermentation conditions, making it suitable for small-scale production or varied products. Continuous fermentation, on the other hand, offers higher productivity and efficiency for large-scale operations, as it maintains a constant supply of nutrients and removes waste products continually. Ultimately, the better option depends on factors such as scale, desired product consistency, and the specific microorganism used.


What does the extended fermentation of grapes produce?

Extended fermentation of grapes primarily produces wines with enhanced complexity and depth of flavor. This process allows for greater extraction of phenolic compounds, which can contribute to a richer mouthfeel, more pronounced tannins, and nuanced aromas. Additionally, longer fermentation can lead to the development of secondary flavors and aromas, such as those from yeast autolysis, depending on the winemaking techniques employed. Overall, extended fermentation can significantly influence the character and quality of the final wine.


What are the types of fermenters?

alcoholic fermentation and lactic acid fermentation


What are advantages of batch fermentation?

Batch Culture:-It is the one of the mode of suspension culture technology which belongs to animal tissue culture.In this culture, cell growth is limited not by nutrients but by accumulation of waste products. In this mode, a higher cell concentration is achieved and cell viability is maintained for larger periods.Advantages:-This is by D.V.Thrinath.


What is fed batch continuous reactor?

There is no fed batch continuous reactor as far as i know. But there are batch, fed-batch and continuous type reactors. Basically a batch reactor is one in which you fill up all the things and lock it down for fermentation while in a fed batch you keep putting the feed in and allow cells to grow as much as possible or until you reach the capacity of the reactor where as in a continuous reactor you keep feeding in and taking out the product continuously that is why continuous type reactors run for long time like weeks or months.


What is needed to start fermentation?

Conditions of brewery must be sanitary. Bugs and/or bacteria can ruin the batch. The tempurature is important. Cold air is best for fermentation. if you have sanitary conditions, the right tempurature, yeast and sugar wort fermentation should happen.


What is sour and mash?

Mash is the crushed grain and water mixture. Sour is the fermentation agent taken from a previous batch. Not all that different from making sour dough bread.
