Match the antibiotics in Group I with the microorganisms that produce them in Group II.
The correct matching of antibiotics in Group I with the microorganisms that produce them in Group II is as follows:
- Streptomycin (P): Produced by {Streptomyces griseus} (i).
- Bacitracin (Q): Produced by {Bacillus licheniformis} (ii).
- Amphotericin B (R): Produced by {Streptomyces nodosus} (iv).
- Chloramphenicol (S): Produced by {Streptomyces venezuelae} (iii).
Thus, the correct option is ( {(P)-(i), (Q)-(ii), (R)-(iv), (S)-(iii)} ), which corresponds to option (B).
The \( F_{121} \) value of a known microorganism with \( Z \) value of \( 11^\circ C \) is 2.4 min for 99.9999% inactivation. For a 12D inactivation of the said microorganism at \( 143^\circ C \), the \( F \) value (in min) is .......... (rounded off to 3 decimal places)
Three villages P, Q, and R are located in such a way that the distance PQ = 13 km, QR = 14 km, and RP = 15 km, as shown in the figure. A straight road joins Q and R. It is proposed to connect P to this road QR by constructing another road. What is the minimum possible length (in km) of this connecting road?
Note: The figure shown is representative.
For the clock shown in the figure, if
O = O Q S Z P R T, and
X = X Z P W Y O Q,
then which one among the given options is most appropriate for P?
