The role of desiccation, filtration, osmotic pressure and radiation in controlling microorganisms

by

In this article, I briefly describe how desiccation, filtration, osmotic pressure, and radiation control microorganisms. Physical methods of microbial control It is necessary to control microorganisms for the prevention of diseases. Microbial growth is controlled either by killing microorganisms or by inhibiting the growth of microorganisms. Microorganisms are generally controlled by the use of physical … Read more >>

Temperature controlling microbial growth

by

In this article, I briefly describe how temperature controls the growth of microorganisms. Microbial control Microorganisms are controlled to prevent transmission of disease and infection. Microbial growth is controlled either by killing microorganisms or by inhibiting the growth of microorganisms. Microbes must be controlled to avoid contamination by their undesirable growth and prevent material deterioration … Read more >>

by

In this article, I briefly describe the blue-green algae, also known as cyanobacteria. The cyanobacteria- oxygenic phototrophic bacteria The blue-green algae (cyanobacteria) are one of the largest and most important groups of bacteria on earth. They belong to the diverse phylum of photosynthetic prokaryotes. They are chlorophyll-containing oxygenic phototrophic bacteria. These bacteria use various photosynthetic … Read more >>

The purple and green phototropic bacteria

by

In this article, I briefly describe the purple and green phototropic bacteria. Phototropic bacteria These are a group of bacteria that derive their energy for growth from sunlight, and their source of carbon comes from carbon dioxide or organic carbon. The phototropic bacteria can be categorized into two groups, i.e., anoxygenic phototrophic bacteria and oxygenic … Read more >>
