OBJECTIVE:

To introduce the student to the downstream processing and purification of biological products of relevance to the pharmaceutical, technical and food industries.

UNIT I	BIO PRODUCTS AND BIOSEPARATION-OVERVIEW	9

Broad classification of bioproducts - Small biomolecules - macromolecules, Stages of downstream processing. Cell disruption for product release – mechanical, enzymatic and chemical methods. Pretreatment and stabilisation of bioproducts.

UNIT II	PHYSICAL METHODS OF SEPARATION	9

Unit operations for solid-liquid separation – filtration - Conventional and cross flow filtration, Filter media and equipment. Sedimentation – Principle, methods, production centrifuges, ultracentrifugation, flocculation, membrane separation –ultrafiltration and reverse osmosis, dialysis,

UNIT III	ISOLATION OF PRODUCTS	9

Extraction- liquid-liquid extraction, solvent extraction principles, extraction process, aqueous two-phase extraction and its applications. Adsorption- Equilibrium and isotherms-adsorption column dynamics-fixed bed adsorption and agitated –bed adsorption.

UNIT IV	PRODUCT PURIFICATION	9

Classification of Chromatographic techniques – chromatographic terms and parameters principles, instruments and practice, adsorption, reverse phase, ion-exchange, size exclusion, hydrophobic interaction, bioaffinity and pseudo affinity chromatographic techniques.

UNIT V	FINAL PRODUCT FORMULATION AND FINISHING OPERATIONS	9

Precipitation of proteins, methods selective denaturation of unwanted proteins, Crystallization principles, batch crystallizers, crystallization of proteins, drying and lyophilization in final product formulation.

TOTAL : 45 PERIODS

OUTCOMES: The students will be able to

• Acquire theoretical knowlegde of unit operations: Filtration, Centrifugation, Protein precipitaition, Crystallisation, Drying, distillation, absorption, liquid-liquid extraction taking into account economic, and technical concerns.
• Calculate dimensions and choosing the internal structure of separation equipment for simple separation applications.
• gain knowledge of the structure and function of biological macromolecules and its separation
