Class 12 Biotechnology Chapter 10 Exercise Solutions
Bioprocessing and Biomanufacturing explains how biological systems are converted into controlled production systems. The chapter starts with the historical importance of penicillin and moves into fermenter design, process modes, product recovery and examples of commercial products.
The NCERT exercise asks students to compare primary and secondary metabolites, explain bioprocess challenges, describe bioreactor components and solve direct application questions. The linked question cards give separate check-solution and expert-solution views for quick practice.

Operational Stages of Bioprocess
A bioprocess has two broad stages. Upstream processing prepares the medium, sterilises equipment, develops inoculum and sets growth conditions. Downstream processing starts after fermentation and focuses on recovery, purification, packaging and effluent handling.
For exam writing, remember the order: stock culture, nutrient medium, sterilisation, inoculum, bioreactor run, recovery, purification and packaging. This route also explains why sterility, aeration, agitation, pH and temperature are repeatedly mentioned in the chapter.
Recovery and Purification of Products
Product recovery depends on whether the product is extracellular or intracellular. For an intracellular product, cells are first separated from the broth, ruptured carefully and then processed to remove debris. The product can then be recovered by extraction or adsorption and purified through precipitation, chromatography, dialysis, reverse osmosis or ultrafiltration.
Solid-liquid separation is usually done by filtration or centrifugation. Reverse osmosis uses pressure to move water across a membrane, while dialysis removes small solutes through a selectively permeable membrane.
