In this article, I briefly describe how different antibiotics inhibit the cell wall synthesis of microorganisms. Antibiotics Antibiotic refers to metabolic substances produced by a microorganism that, even in small quantities, can inhibit or harm other microbes. Vuillemin, in 1898, introduced the concept of antibiosis, where one organism eliminates others to survive. However, this early … Read more >>
In this article, I briefly describe different soil microorganisms that constitute the soil microbial flora. Soil The soil is the land surface of the earth, which provides the substratum for plant and animal life. The soil represents a favorable habitat for microorganisms and is inhabited by many microorganisms, such as bacteria, fungi, algae, viruses, and … Read more >>
In this article, I briefly describe the types of associations among soil microorganisms. Microbial Ecosystem The total microbial flora along with the soil’s physical composition and physical characteristics, includes the microbial ecosystem. It is the sum of the biotic and abiotic components of soil. The soil microorganisms exhibit many different types of interactions or associations. … Read more >>
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 their growth of microorganisms. Microorganisms are generally controlled by the use of physical … Read more >>
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 their growth. Microbes must be controlled to avoid contamination by their undesirable growth and prevent material deterioration and spoilage. … Read more >>
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 >>
In this article, I briefly describe the purple and green phototrophic bacteria. Phototrophic 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 phototrophic bacteria can be categorized into two groups, i.e., anoxygenic phototrophic bacteria and oxygenic … Read more >>
