Solved in 2 steps
- Why are there so many antibiotic-producing organisms in soils?Why are there so many antibiotic-producing organisms in soils?Explain itWhat are biofertilisers? A farmer is advised to add a culture of bacterium in the soil before sowing the crop. Name the bacterium in the culture. How is this bacterium useful to the crop?
- What is the difference between a bactericidal antibiotic and an antibiotic that is bacteriostatic? Examine the zone of inhibition around each disk for the presence of micro colonies within the zone. What do these micro colonies represent? Why didn't plants evolve anti-microbial agents against all the microbes in their environment?Why is nutrient broth considered as a universal growth medium for bacteria?While you were working on the oil spill problem, you received a report showing that the bacteria you intend to use are not present in significant quantities in that area of the sea. How I can Find a solution to this shortage?
