it is a closed system, were no new nutrients are added. the bacteria grow and mutiply. they bacteria go throught the lag, and log phase into the stationay phase. at the same time the nutrients are depletitng. this eventually results in the bacteria entering the death phase maily due to lack of nutrients.
this is difffernt to fed batch as nurtients are added to keep nutrient condtions concentration constant. thsi prolongs the log and stationary phase. particualy usefull for produceing secondary metabolites. this will also eventually enter the death phase, not due to lack of nutrient but due to build up of toxins (waste products of metabolisum)
a continuous ferenetor keeps nutrient concentration constant and number of bacteria constant, it dose this by peridocally removeing some of the bacteria. this genrally maintains the bacteria in the log phase, as their is no build up of toxins and no competion for nutients.
fermentor is a large vessel to carry out the fermentation process without any adverse conditions like contamination,etc
rem is a comment that is only seen if you edit the batch echo actually is printed when the batch is running
"Batch processing" refers to the execution of multiple commands on a computer. Batch jobs are often used to automate a process which needs to be done on many files, since they do not typically need user input once started.
You can only do it with regetit.exe, and plus if you are asking to change it with a batch file ... trying to make a virus?
Batch processing enables work to be done simultaniously whilst the workers are able to play football in the courtyard whilst production is taking place. this can occur in the workplace and is highly recommended to anyone who wishes to try this. An example of batch processing is the way that credit card companies process billing. The customer does not receive a bill for each separate credit card purchase but one monthly bill for all of that month's purchases. The bill is created through batch processing, where all of the data are collected and held until the bill is processed as a batch at the end of the billing cycle.

A batch fermenter allows microbiologists an efficient and sterile way to reproduce microorganisms. The batch fermenter is automatically sterilized at the end of each batch.
Acholic fermentation lactic acid fermentation wine fermentation
hi, fermenter is generally used for wine and beer and other products like penicillin,acetone,citric acid etc. before a batch starts fermenter need to be sterilized to kill all unwanted bacteria. steam can provide cell disrupting temperature at 121 c temperature and 15 lbs pressure.that's why steam passed through the fermenter and it takes long to cool fermenter that's why cool water passed.
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.
Fermenter are of two types 1. Aerobic fermenter 2. Anaerobic fermenter
The fermenter is surrounded by a jacket of cold water to regulate the temperature of the reaction medium.
