What is lignin? Lignin is a complex, high-molecular-weight polymer made mostly of phenolic compounds. It is found in the cell walls of vascular plants, especially in the secondary cell wall during the development of xylem, phloem fibres, and sclerenchyma cells, which give the plant strength, support, and waterproofing. It is made up of three main … Read more

Brucella is an intracellular parasite which causes epizootic abortions for animals, and septicemic febrile disease or localized infections of tissues, bones or organ systems of humans. Brucella species are very meticulous and require a rich nutrient environment to develop. Additionally, Brucella species are highly infectious, and therefore extreme caution should be exercised when handling.
Staphylococcus aureus is a Gram‑positive, facultative anaerobic bacterium, usually found in clusters that resemble grapes and typically 0.5–1µm in diameter. Harbor, as a commensal organism, in the human nasal passages, skin, and mucous membranes of 20–30% of people without causing disease It is an opportunistic pathogen that can cause a wide range of infections—from simple … Read more
The phyllosphere refers to the entirety of a plant’s above-ground surface, which provides a habitat for microorganisms, particularly in the aerial components such as leaves, stems, flowers, and fruits. Phyllosphere Microorganisms – These are microbiological entities that inhabit the aerial surfaces of plants, particularly the leaf surface (phylloplane). What is Phyllosphere? Phyllosphere – the aerial … Read more
What is Pedogenesis? Pedogenesis is the natural process of soil formation resulting from the interplay of physical, chemical, biological, and climatic elements throughout time. Chronology – In 1883, Vasily Dokuchaev posited that soil is a product of climate, vegetation, parent material, and temporal factors. In 1941, Hans Jenny established the CLORPT model—Climate, Organisms, Relief, Parent … Read more
Pectin is a complicated polysaccharide that is mostly found in the cell walls of plants, notably fruits. It is a structural heteropolysaccharide made up mostly of units of galacturonic acid. Pectin is a glue that holds plant cells together, making the plant tissue strong and stable. In the culinary sector, it is often used as … Read more
