| 1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
| 2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
| Q1 ⇒ An internal draft tube is preferrred to an external draft tube because it is easier to clean and sterilize a reactor [other wrong options] [Discuss in forum] |
| Q2 ⇒ During the log phase cell numbers increase exponentially because cells are autocatalysts [other wrong options] [Discuss in forum] |
| Q3 ⇒ The contents in bubble column and air lift reactor are mixed through compressed air [other wrong options] [Discuss in forum] |
| Q4 ⇒ In an airlift bioreactor, the air sparging region is called air riser [other wrong options] [Discuss in forum] |
| Q5 ⇒ In the accelerated phase, cell starts to increase and the division rate increases to reach a maximum [other wrong options] [Discuss in forum] |
| Q6 ⇒ The maximum specific growth rate of an organism depends on All of these [other wrong options] [Discuss in forum] |
| Q7 ⇒ Heat transfer rates (per unit volume) will be lowest in Continuous packed bed reactor [other wrong options] [Discuss in forum] |
| Q8 ⇒ The increased air flow rate in bubble column fermenter can cause excessive foaming and high retention of air bubbles in the column which decreases the productivity of the fermenter [other wrong options] [Discuss in forum] |
| Q9 ⇒ Chemostats work on the principle of maintaining uniform nutrients concentration [other wrong options] [Discuss in forum] |
| Q10 ⇒ If the specific growth rate, μ. is constant with time during the exponential growth period, the equation correlating bacterial number density Cn), cell number concentration with respect to time can be expressed as Cn= Cn0 exp[μ (t - t0)] [other wrong options] [Discuss in forum] |
| Q11 ⇒ The main function(s) of a draft tube in an air lift fermenter is/are to distribute shear forces throughout the reactor and minimise bubble coalescence [other wrong options] [Discuss in forum] |
| Q12 ⇒ The height to diameter ratio (H/D) for the tank fermenters is <3 [other wrong options] [Discuss in forum] |
| Q13 ⇒ The monod model predicts that the specific growth rate will increase with the concentration of the growth limiting substrate until it reaches a maximum value [other wrong options] [Discuss in forum] |
| Q14 ⇒ Which of the following is not correct for the Monod model and the Michaelis Menten Model? The Monod model was derived from an analysis of the mechanism of microbial growth [other wrong options] [Discuss in forum] |
| Q15 ⇒ The function(s) of the draft tube in an airlift bioreactor is all of the above [other wrong options] [Discuss in forum] |
| Q16 ⇒ Which of the following is correct for the prediction of time requirement in a batch fermenter? Both (a) and (b) [other wrong options] [Discuss in forum] |
| Q17 ⇒ During the exponential phase the maximum specific growth rate equals specific growth rate as concentration of growth limiting substrate is much greater than the monod constant [other wrong options] [Discuss in forum] |
| Q18 ⇒ The diameter of the baffles in a standard stirred tank bioreactor ranges from 1/10th - 1/12th of the tank diameter [other wrong options] [Discuss in forum] |
| Q19 ⇒ Which of the following is incorrect? STF can't be used for high viscosity medium [other wrong options] [Discuss in forum] |
| Q20 ⇒ The relatively large volume (10 to 40% of total fermenter volume) of the seed culture is employed to decrease the overall fermentation time [other wrong options] [Discuss in forum] |
