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.
Bacteriophages are mainly composed of high-quality proteins encapsulating a DNA or an RNA genome, and possess a very simple or intricate structure.
Felugen reaction or cytochemical staining of DNA is a method of identifying DNA or other chromosomal material in a given cell specimen.
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
There is no doubt that mushrooms are super delicious but some of the gourmet varieties are very expensive and is quite difficult to get it fresh.
Water contains a large number of bacteria. There are lots of methods by which we can estimate the number of bacteria present in water. Filter disc method is one of the important methods
Bacteriophages are obligate intercellular parasites. They utilize the biosynthetic machinery of the host for their multiplication. They make an entry into the bacterial cell by first making a landing on the bacterial cell wall
Rhizobium lives in soil and in the roots of legumes and non-leguminous plants. Bacteria exclusively depends on the root exudates that facilitates the growth of the rhizobial cells.
One of the best medium for growth of microorganism is milk. Both raw milk as well as the pasteurized milk contain varied microorganisms. Thus, one of the popular tools for determination of the milk quality is development of Methylene Blue Reductase.
Prepare urea agar slant and streak in its surface with isolated colonies of the Enteric organism. Incubate the slant in a incubator for about 48 hours at a temperature of 35C to 37C.
We Labmonk, some scientific researchers unite to design a platform for getting sources of different lab protocols and discuss various research related issues.
