Glass serological pipettes are usually described as long, cylindrical measuring tools used for transferring the Liquid volumes that are needed in Cell Culture work, And many other wet-lab procedures, and it is worth mentioning that they are typically calibrated for delivering (TD) readings with graduations marked clearly,even if the spacing sometimes looks tight. These pipette’s … Read more
Ever peered through a microscope and marveled at the microscopic universe it unveils? It’s like being Alice in her Wonderland, but instead of falling down a rabbit hole, you’re diving into the magical world of cells, bacteria, and more. Yet, have you ever wondered about the parts of this wonder-making machine and their functions? Let’s focus (pun … Read more
The process of collecting bacteria from the air for analysis involves several techniques, one of the simplest being the utilization of open Petri dishes filled with a growth medium. These dishes are exposed to the air, allowing airborne bacteria to settle and subsequently grow on the medium, which can then be examined to identify the … Read more
Exploring the microscopic world within soil requires precise techniques for the effective sampling of microorganisms, such as bacteria. These organisms play crucial roles in various ecological processes, including nutrient cycling, and understanding their presence and diversity is vital for both scientific research and environmental monitoring. Two widely recognized methods facilitate the direct observation of these … Read more
When examining water samples for bacterial content, direct microscopic observation often yields minimal visible bacteria due to their small size and low concentrations. To overcome this challenge and accurately assess the bacterial population in water, scientists employ the filtration technique. This method is pivotal for both quantifying bacteria per unit volume of water and analyzing … Read more

What is Satellitism Test? Definition of Satellitism Test The Satellitism Test is a biochemical assay used to differentiate Haemophilus influenzae from other Haemophilus species based on their growth factor requirements. In this test, H. influenzae grows proximally to Staphylococcus aureus colonies on blood agar due to the latter’s production of necessary growth factors, a phenomenon … Read more
Alcohol fermentation, also known as ethanol fermentation, is a sophisticated biotechnological procedure wherein specific sugars, namely glucose, fructose, and sucrose, undergo a transformation into ethyl alcohol (ethanol) and carbon dioxide. This transformation is facilitated by certain microorganisms, predominantly the yeast species Saccharomyces cerevisiae, as well as specific bacterial strains. Central to the realm of biotechnology, … Read more
