Microorganisms in food Spoilage – Microbes in food spoilage

• Published on May 22, 2024 • 15 min readby Editorial Team

Chemical reactions that produce sensual changes that are offensive in food are controlled by a wide range of microbes that utilize food as a source of carbon and energy source. The organisms that cause these changes comprise prokaryotes (bacteria) as well as single-celled organisms that lack defined nuclei and organelles, as well as eukaryotes unicellulated (yeasts) as well as multicellular (molds) organisms that possess organelles and nuclei.

Pasteurisation was developed by an French Scientist known as Louis Pasteur during the nineteenth century. Pasteur realized that warming milk up to a high temperature , then cooling it quickly prior to packaging or bottling could preserve it for a longer time.

Anabolism vs Catabolism – Differences Between Anabolism and Catabolism

• Published on May 22, 2024 • 15 min readby Editorial Team

What is Anabolism? Anabolism Definition Anabolism is the metabolic process in which simpler molecules are synthesized into more complex ones, requiring energy input. Examples of Anabolic Reactions 1. Photosynthesis: Photosynthesis exemplifies an anabolic reaction quintessential to autotrophic organisms. Within the chloroplasts of plants, a sequence of biochemical transformations ensues, culminating in the conversion of carbon … Read more

Difference Between Multicellular and Unicellular Organisms

What are unicellular organisms? Examples of Unicellular Organisms Unicellular organisms are remarkable entities that carry out all life processes within a single cell. These organisms can be found in various environments, from freshwater to marine habitats, and even in extreme conditions. Their simplicity, in terms of cellular structure, is contrasted by the diverse roles they … Read more

Difference Between Lytic and Lysogenic Cycle

• Published on May 22, 2024 • 12 min readby Editorial Team

What is Lytic Cycle? The lytic cycle is a fundamental process in the life cycle of certain viruses, particularly bacteriophages, which are viruses that infect bacteria. This cycle is characterized by the following sequential events: The term “lytic” is derived from “lysis,” referring to the rupture and death of the host cell. This cycle contrasts … Read more

Facilitated Diffusion vs Active transport

• Published on May 22, 2024 • 12 min readby Editorial Team

What is Facilitated Diffusion? Facilitated diffusion is a specialized mechanism of passive transport across biological membranes. Unlike simple diffusion, which allows molecules to move freely based on their concentration gradients, facilitated diffusion employs specific transmembrane proteins to assist in the transport of molecules or ions. This process is spontaneous and does not necessitate direct energy … Read more

Colorimeter vs Spectrophotometer

• Published on May 22, 2024 • 18 min readby Editorial Team

What is Colorimeter? A colorimeter is a sophisticated scientific instrument dedicated to the domain of colorimetry, the science of measuring the absorbance and transmittance characteristics of light as it propagates through a liquid medium. The underlying principle governing its operation is the renowned Beer-Lambert’s law, which correlates the light absorbed or transmitted by a sample … Read more

• Published on May 22, 2024 • 12 min readby Editorial Team

What is a Spectrometer? Types of Spectrometers Spectrometers, pivotal instruments in the realm of scientific research, are designed to detect and analyze various properties of substances. These devices are categorized based on their specific functionalities and the type of measurements they are engineered to perform. Herein, we delve into the primary types of spectrometers and … Read more

Coding Strand vs. Template Strand – Difference Between Template and Coding Strand

• Published on May 22, 2024 • 13 min readby Editorial Team

The Difference between a template and a coding strand is primarily based on two characteristics: directional polarity and function. The two distinct strands of double-stranded DNA are the template strand and the coding strand, with the former functioning as a base to transcribe mRNA and the latter determining the correct base sequence of the mRNA. … Read more
