The basic objective of this experiment is to isolate auxotrophic antibiotic resistant mutant bu induced mutagenesis in bacteria by method of replica plating
Phosphate solubilising microorganisms play vital role in providing phosphorus to the plants. They are slowly becoming vital organisms for improvement of soil.
Rhizobia are the bacterium that infects the roots of leguminous plants and form nodules where it fixes nitrogen.
The basic objective of this experiment is to calculate the generation time and specific growth rate of bacteria from the graph plotted with a given set of data.
When there is a hereditary change in the base sequence of a DNA it is called mutation. Very few mutations are either neutral or beneficial to organisms but usually they cause harm to living beings as that result
Gelatin is a type of protein obtained from animal protein collagen. The main use of gelatin is as a solidifying agent in food. The process of gelatin hydrolysis is used for determining bacteria proteolysis
Sub culturing is the method of transferring microorganisms from one growth container to another, thereby offering them with fresh supply of nutrients either in a solid or a liquid medium.
Spread plate method is a process of isolation and enumeration of bacteria and other microorganisms from a mixed culture. It helps in measuring the quantity of bacteria present in the solution
Hanging drop method is a process of observing the motility in bacteria and is a wet mount method. The method is used in dark illumination and gives a very clarified view of the microbial motility
