Batch and semi-batch processes are used to handle usually low-volume high-value products such as fermentation products including amino acidsand antibiotics recombinant DNA products and specialty chemicals Owing to highvalues of these products pro?tability can be improved greatly even with marginalimprovements in yield and productivity
Jan 25 2001 · A fed-batch process is intermediate between a batch process and a continuous process Fed-batch fermenters which enable inflow of fresh nutrients with continuous or periodic withdrawal of broth can overcome the major limitations of batch processes without the disadvantages of continuous processes
Of these, 51 were batch and 11 continuous. Findings indicate that the batch fermentation process with yeast recycle is superior for the following main reasons. The process parameters are more easier to measure and invariably control and manage.
... In a continuous fermentation process, the medium is fed into the bioreactor reactor continuously, but is also continuously removed. In Brazil, 83% of distilleries that produce first generation bioethanol rely on fed-batch processes, while continuous processes account for only 17% (Godoy et al., 2008). ...
The kinetic constants ( Ks, Kp, ?max) of batch fermentation were 2,0 kg.m -3, 97,9 kg.m -3, 0,476 h -1 respectively. Output per a batch is 3 623 kg and a single fermenter can produce 514 batches per year. From it follows that the year vintage is close to the actual 1 862 222 kg. Therefore, the number of 70 m 3 fermenters required 4 bioreactor.
A large, appropriate – sized fermenter is supposed 70 m 3. The operating volume is 52,5 m 3. Batch fermentation was perform with 200 g/l glucose concentration. Fermentation time, is 11,4 hours with ethanol stripping 69,1 g.l -1 and 12 hours 75,9 g.l -1 without stripping. Computing is stopped when glucose alteration obtain 97 percent.
