Rhizobium The Nitrogen-Fixing Bacterium

Rhizobium: The Nitrogen-Fixing Bacterium

Introduction Rhizobium is a remarkable bacterium known for its unique symbiotic relationship with the roots of leguminous plants. Found primarily in root nodules of plants like peas, beans, and lentils, Rhizobium plays a crucial role in biological nitrogen fixation. This process converts atmospheric nitrogen, which plants cannot directly use, into ammonia—a soluble form that plants […]

Bacillus subtilis– Morphology, Habitat, Diseases & Industrial Applications

Bacillus subtilis– Morphology, Habitat, Diseases & Industrial Applications

Introduction Bacillus subtilis is a Gram-positive, endospore-forming bacterium commonly found in soil, air, water, and decaying plant matter. This rod-shaped, motile microorganism is a facultative aerobe, meaning it can survive in both oxygen-rich and oxygen-poor environments. Known for producing resistant endospores, B. subtilis can endure extreme heat, dehydration, and UV radiation. Thanks to its well-studied

Basics of Food Microbiology in

Introduction The field of microbiology known as food microbiology focuses on techniques for preventing the growth of microorganisms, particularly foodborne pathogens and spoilage microbes, in food during handling, processing, and storage. Food microbiologists study the microbes that are essential to food production. This broad subject known as food microbiology includes the pathogens that cause foodborne

Immune System Cells

Immune System Cells: The Body’s Cellular Defenders

Introduction The human immune system is a complex network of specialized cells, tissues, and organs designed to protect the body against infections, cancer, and foreign invaders. At the heart of this system are the immune cells—each with a unique function in detecting, responding to, and remembering pathogens. These vital defenders originate from a common source:

Biochar Properties, Production, and Applications

Biochar: Properties, Production, and Applications

Introduction to Biochar Biochar: Thermally treated biomass that consists primarily of carbon. Biochar, commonly known as black carbon, is produced from organic materials high in carbon (C) and is frequently discovered in soils in extremely stable solid forms, such as deposits. Bio-chars can last for thousands of years in the soil at various depths. Charcoal,

Ribonucleic acid (RNA) Types, Structure, Function & Role in Protein Synthesis

Ribonucleic acid (RNA): Types, Structure & their Function

Introduction to RNA Ribonucleic acid (RNA) is a fundamental biomolecule present in most living organisms and many viruses. It consists of a ribose sugar, phosphate backbone, and nitrogenous bases — adenine (A), guanine (G), cytosine (C), and uracil (U) (in place of thymine in DNA).  The majority of RNA is single-stranded, however there are particular

Antimicrobial Resistance (AMR) Mechanisms and Alternatives

Antimicrobial Resistance (AMR) Mechanisms and Alternatives

Introduction to Antimicrobial Resistance (AMR) Antimicrobial Resistance (AMR) occurs when microorganisms—such as bacteria, viruses, fungi, and parasites—evolve to survive exposure to drugs that once killed or inhibited them. It poses a major threat to global health, food security, and development. According to WHO, by 2050, AMR could cause 10 million deaths annually if not controlled.

Microscopy Principles, Types, and Applications

Microscopy: Principles, Types, and Applications

Introduction to Microscopy Microscopy is the scientific discipline of using microscopes to observe samples and items that are too small to be seen with the naked eye (objects that are not within the resolution range of the normal eye). Microscopy plays a crucial role in various scientific disciplines, allowing researchers to observe and analyze microscopic

Microbiology From Microorganisms to Career Opportunities

Microbiology: From Microorganisms to Career Opportunities

Introduction Microbiology is the scientific study of microorganisms—tiny, often microscopic organisms also known as microbes. These include a diverse group of life forms such as bacteria, archaea, algae, fungi, protozoa, and viruses. Microbiology plays a crucial role in understanding the structure, classification, function, and behavior of these organisms, as well as how they can be
