Answer 1

Production of active dry yeast

Explanation:

• The up-stream processing in production of active dry yeast includes media and other raw material preparation.
• It further includes production of seed culture , and large scale fermentation process.
• Downstream processing involves harvesting , packaging and filtration process.
• The bio-processing is considered to be an important process because pure form of active dry yeast is obtained and it is further used in the production of carbon-dioxide for dough maturation and also for flavor development in bread and other like items.
