Sterilization (microbiology)

Sterilization refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents such as prions present in or on a specific surface, object, or fluid. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic. (Wikipedia).

Growth Media and Pouring Plates - Microbiology techniques

One of the first things you learn in microbiology is how to make media, and when you think about it, it makes sense. Microbes are tiny and only have what we give them. So if we don't provide what they need, they simply won't grow. Growing microbes can be very rewards wether you're making y

Gravity Filtration and Vacuum Filtration

The first laboratory technique that we will learn together is a very simple one, filtration. This is how we separate a mixture of liquids and solids. There are two common ways a chemist will perform filtration, those being gravity filtration and vacuum filtration. These are very easy to un

Taxonomy of Bacteria: Identification and Classification

We've been looking at bacteria for a few centuries now, so how do we categorize them? We love to classify things and put them in groups, so how does that work for bacteria? Well let's learn about Gram-staining, antigens, other phenotypic and genotypic properties, and we will be well on our
