In a bioprocess, assume that only cell mass is formed. Due to a variation in process condition, if the microbial cell yield has halved, what would be the rate of substrate consumption to maintain the same rate of cell mass production?

In a bioprocess, assume that only cell mass is formed. Due to a variation in process condition, if the microbial cell yield has halved, what would be the rate of substrate consumption to maintain the same rate of cell mass production? Correct Answer It would be doubled

Consider the growth of a microorganism in batch culture. When the substrate concentration is high, the cell density doubles every 0.75 h, the observed substrate yield coefficient is 0.3 g DCW/g, and substrate consumption is allocated towards biosynthesis (60%), maintenance (10%), as well as product formation (30%). The product formation is strictly growth-associated. The batch reactor is inoculated with 0.01 g DCW/L and 10 g/L substrate. Estimate the maximum cell density (after lag phase).
In balanced growth phase of a cell,
P. All components of a cell grow at the same rate.
Q. Specific growth determined by cell number or cell mass would be the same.
R. The growth rate is independent of substrate concentration.
S. The growth rate decreases with decreasing substrate concentration.
The pie chart given below shows the fuel consumption by five vehicles V1, V2, V3, V4 and V5. In a month total fuel consumption by all five vehicles is 720 litre. Fuel consumption of a particular vehicle is shown in terms of degree with respect to the total fuel consumption by all these five vehicles. J1 = Difference between the fuel consumption of V4 and V5. J2 = Difference between the fuel consumption of V1 and V2. What is the value of J2 – J1?

The given bar graph represents data of the production of paper (in ten lakh tonnes) by three different companies X, Y and Z during the years 2008 to 2012. The x-axis shows the 'years' and the y-axis represents the 'production of paper (ten lakh tonnes)'. (Note: The data shown is only for mathematical exercise. They do not represent actual figures.)  The total production of Company Y during 2008 and 2009 and Company X for 2011 and 2012 taken together is p% (p is correct to the nearest integer) more than the total production of Company Z during 2010, 2011 and 2012. The total production of Company Z during 2008 and 2009 taken together is q% (q is correct to the nearest integer) less than the total production of Company X during 2008, 2009 and 2012 and Company Y during 2010 and 2011 all together.  What is the positive difference between p and q ?
