Question

In batch fermentation:

• A. substrates are added to the system all at once and runs until product is harvested
• B. nutrients are continuously fed into the reactor and the product Is siphoned off during the run
• C. new batches of microorganisms are screened for increase yield
• D. small-scale production is used to synthesise product.

Answer 1

The correct option is A substrates are added to the system all at once and runs until product is harvested

Fermentation is a metabolic process which converts carbohydrates to alcohols, organic acids are gases by the activity of the enzyme of microbial origin.

Batch fermentation is a process where the microorganism is inoculated into a fixed volume of medium. As the growth takes place the nutrients that are consumed and the product of growth keeps getting stored in the fermenter.

In batch fermentation, the mass production is done as separate batches.

So, then the correct option is 'substrates are added to the system all at once and runs until product is harvested'
