Traditional Water Purification Methods

Traditional water purification methods are prominently used in rural communities worldwide. Traditional ways to purify water include some rudimentary methods to remove impurities. Long years ago, people utilized the available resources like sand, cloth, stone etc. to purify water. Those basic methods only make the water quality acceptable for drinking purposes. But, somewhere these old …

Difference Between Agarose and Polyacrylamide Gel

The difference between agarose and polyacrylamide gel relies upon factors like origin and molecular complexity. Both gels help in biomolecular separation, due to their porous nature. We can separate, identify and purify different biomolecules using agarose and polyacrylamide gels. 1. Origin: Agarose is a natural polymer extracted from several red seaweeds. So, it is a …

Chlorination in Wastewater Treatment

Chlorination is a disinfection method used in the wastewater treatment plant. It helps in the destruction of microorganisms from the running wastewater. Microorganisms can be pathogenic or non-pathogenic. Wastewater contains pathogenic enteric microorganisms that impose severe health problems. Typhoid, cholera, dysentery etc., are common waterborne illnesses. And wastewater treatment aims to reduce the possibility of …

RBC Count Method

The RBC count method comes under haemocytometry, which quantitatively measures the number of RBCs in a blood sample. Haemocytometer or Neubauer’s chamber slide is a manual method to count RBCs. Nowadays, more accurate or automated devices have been developed like electrometric and photometric counters that can count the cell constituents of the blood sample. It …

Genetic Codons

Genetic codons are the gene sequences which encodes specific amino acids that polymerize to form proteins. DNA is the heritable material that serves as a source of the hereditary unit, which transfers genetic information from one to the next generations. Therefore, in a cell, DNA is a director that mediates the synthesis of proteins. A …

Difference Between Cofactor and Coenzyme

The difference between cofactor and coenzyme is mainly characterized based on chemical nature and function. Cofactors constitute a large group of helper molecules (inorganic or organic). Conversely, cofactors are small organic molecules. Coenzymes significantly act as carrier materials to convert the inactive protein (the apoenzyme) into the active form (holoenzyme). In contrast, cofactors serve as …

Cheese Production

Cheese production or Caseiculture makes the use of raw materials, bacterial culture, and rennet to process the end-product, i.e. cheese. Cheese comes in different varieties by the differences in the ingredients and the processing of cheese. Cheesemaking is accomplished by using milk, either in a raw or pasteurized form. Depending upon the processing method, cheese …
