Question

the success of continuous fermentation process invariably depends on​

Answer 1

Answer:Abstract

Studies were conducted with 62 Brazilian distilleries during the last nine years to elicit the advantages and disadvantages of continuous and batch fermentation 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 particular, it is less susceptible to bacterial and wild yeast contamination which otherwise would invite hosts of problems including decrease in productivity. In a case study presented, the increase in output (of 3.3 million litres) through the replacement of a continuous process with a batch process resulted in payback within the year. While the continuous system is relatively cheaper to install, this is negated by poor productivity levels associated with bacterial and wild yeast contamination as it does not lend itself to be cleaned more frequently, the additional costs of antibiotics to address this and yeast shocks when they pass from one fermenter to other where the composition of the substrate (namely alcohol and sugars) and temperature are both different. This suggests why 83% of the Brazilian distilleries have adopted the batch process and new ones are also opting for this as process of choice.
