Zoology is the biological discipline devoted to the study of animals and the animal kingdom. Also referred to as animal biology. Zoology is the study of the connection between the animal kingdom and their environments, including taxonomy, habits, structure, embryology, distribution, evolution, and extinct species. Zoology is the branch of biology concerned with animal life. … Read more
What is Agrobacterium? There are many types of Gram-negative bacteria in the genus Agrobacterium. They can be harmful to plants and are also useful for genetic engineering. It causes tumours in plants by moving a piece of DNA known as T-DNA from its Ti or Ri plasmid into the plant genome. This causes cells to … 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

Industrial fermentation processes leverage a wide array of raw materials, with a significant emphasis on utilizing cost-effective and readily available sources. Among these, agricultural by-products stand out due to their abundance and potential for repurposing. The interest in these materials stems from several key factors: The concept of transforming ‘wastes into resources’ is not just … 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
What is In Vitro Fertilization (IVF)? Why IVF is done? IVF is performed for various reasons related to infertility and certain health conditions. Here are some common reasons why IVF may be done: Additionally, for individuals who do not have a functional uterus or face significant health risks during pregnancy, IVF with a gestational carrier … Read more
