Concept explainers
(a)
Interpretation:
Taking the basis of 100 kg of acidified broth fed into the first extraction unit, the flow diagram of this process should be drawn and the degree of freedom should be found with the analysis of the entire labeled variable in the process.
Concept introduction:
In this case we study the extraction of penicillin by fermentation process considering its dependency on pH. The flowchart is drawn to understand the concept with all steps.
(b)
Interpretation:
The ratio of (Butyl acetate/ acidified broth) in kg and (alkaline solution / acidified broth) in kg and the fraction of penicillin in the product should be calculated. The mass fraction of the penicillin in the product solution should also be calculated.
Concept introduction:
In these we use the basic mathematics for finding the ratio and fraction of penicillin in the production.
(c)
Interpretation:
The reason for the given statements should be determined.
Concept introduction:
In this we study the extraction process that take place in unit(I) and(II) and how it is carried out by adjusting the ph value of aqueous phase.
(d)
Interpretation:
Two possible reasons for the rejection of given process should be identified.
Concept introduction:
In this we study the alternative method for the production of penicillin from the broth fermentation.

- The addition of a small amount of a salt, such as (NH4)2SO4, to a solution containing a charged protein increases the solubility of the protein in water. This observation is called the salting-in effect. However, the addition of large amounts of salt can decrease the solubility of the protein to such an extent that the protein precipitates from solution. This observation is called the salting-out effect and is used widely by biochemists to isolate and purify proteins. Consider the equilibrium PXν(s) ⇋ Pν+(aq) + ν X−(aq), where Pν+ is a polycationic protein of charge ν+ and X− is its counterion. Use Le Chatelier’s principle and the physical principles behind the Debye–Hückel theory to provide a molecular interpretation for the salting-in and salting-out effects.arrow_forwardSulfuryl fluoride (SO2F2) is a commercial fumigating chemical that can be synthesized from the following reaction: SO2 + F2 ↔ SO2F2.
