A | Clostridium butylicum | I | Ethanol |
B | Saccharomyces cerevisiae | II | Streptokinase |
C | Trichoderma polysporum | III | Butyric acid |
D | Streptococcus sp. | IV | Cyclosporin-A |
(A) Clostridium butylicum: This microorganism is known for producing butyric acid, a short-chain fatty acid.
(B) Saccharomyces cerevisiae: This yeast is widely used in fermentation processes to produce ethanol.
(C) Trichoderma polysporum: This fungus is used in the production of cyclosporin-A, an immunosuppressant drug.
(D) Streptococcus sp.: This bacterium produces streptokinase, an enzyme used in medical treatments to dissolve blood clots.
The correct matching is shown below:
\[ \begin{array}{|c|c|} \hline \textbf{Microorganism} & \textbf{Product} \\ \hline \textbf{A.} \ Clostridium\ butylicum & \text{Butyric Acid (III)} \\ \textbf{B.} \ Saccharomyces\ cerevisiae & \text{Ethanol (I)} \\ \textbf{C.} \ Trichoderma\ polysporum & \text{Cyclosporin-A (IV)} \\ \textbf{D.} \ Streptococcus\ sp. & \text{Streptokinase (II)} \\ \hline \end{array} \]
Thus, the correct match is:
\[ A \to III, \quad B \to I, \quad C \to IV, \quad D \to II \]
Explanation:
This concludes our solution.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :

A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
