MICROBIOLOGY

Introduction: Single-cell protein (SCP), often called microbial protein, is a type of crude or refined protein obtained from filamentous fungi, algae, yeasts, molds, microbes, or bacteria. It is edible and can used directly either as animal feed or human food supplements, that usually contain above 40% of crude protein on dry weight bases. Due to […]

Introduction: Parasitic disease, a public health issue, is a type of infectious disease that is caused by parasites which live on or in a host organism.  In annual, millions of morbidities and mortality is caused by these infections which is one of the most devastating and prevalent infections. It is a type of infectious disease

Introduction: Type of contaminants: Microorganisms in Bioremediation: Aerobic bacteria Many of these bacteria grow in the presence of oxygen that use the contaminant as the sole source of carbon and energy. It degrades pesticides and hydrocarbons, both alkanes and polyaromatic compounds. Examples: Pseudomonas, Alcaligenes, Sphingomonas, Rhodococcus, and Mycobacterium Methanotrophs/ Methylotrophs Bacteria that convert methane into

Background: Introduction: Bacterial growth is a complex process that involves both catabolic (breakdown of cell constituents and metabolites) and anabolic (biosynthesis of cell constituents and metabolites) process. Basically, bacterial growth curve is sigmoid shows various recognizable stages of the growth of bacteria- lag phase, log phase or exponential growth phase, stationary phase, and the death

Introduction: Types: Exotoxin Fig: Different types of bacterial toxins Endotoxin Endotoxins are the outer parts of the bacterial cell wall especially Gram-ve bacteria such as E. coli, Shigella, Salmonella, Neisseria, Haemophilus Pseudomonas, and other pathogens. Basically, it is released upon cell death, autolysis, phagocytic digestion, and cell lysis which trigger a widespread inflammatory response. Although

Introduction: Biopesticides are certain types of natural, biologically occurring pesticides that are used to control various agricultural pests and pathogens. It is derived from such natural materials as animals, plants, certain minerals, and microorganisms such as bacteria, cyanobacteria, and microalgae. It is a biological agent, class of pesticides that tend to pose fewer risks than

Introduction: Pathogens are defined as organism that are taxonomically widely diverse that cause diseases to their respective hosts with the severity of symptoms of diseases. It comprises not only viruses’ bacteria and fungi but also unicellular and multicellular eukaryotes. Generally, depending on their relationship to the host, microorganism can be classified as saprophytes and parasites.

Introduction: History: Principle: This computational approach is a branch of vaccinomics that is used to design vaccines predicting epitopes from the genetic information of the pathogens. The principle of reverse vaccinology involves the availability of the whole genome sequence of the organism and uses computational analysis to identify genes that encode proteins on the surface

Introduction: The unavoidable by-product of human activities results in a solid waste which tends to increase with rapid urbanization, improved living standards and changing consumption patterns. It is the unwanted or useless solid materials generated from combined residential, industrial and commercial activities in a given area.  Solid waste management a critical component that include collection,

Introduction: It is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by enhancing the supply, availability, accessibility of several primary nutrients to the host plant. Bacteria, fungi, and mycorrhizae, belonging to the Bacillus, Lactobacillus, Azotobacter, Pseudomonas,
