Microbiology Lab

 

Everywhere you look, even though you can't see them, there is a hidden world of microorganisms. Microbiology is the study of this hidden world of organisms that affect our health, help make our food, and influence our environment.

Definition of Microbiology

Did you know that you're mostly a microbe? There are more microbial cells in your body than your own cells. Microbes are found everywhere: in and on your body, in streams and rocks, on your smart phone screen, and in your food. Despite their bad reputation, microbes are mostly beneficial or have a neutral effect on our lives.

Microbiology is the scientific study of these microorganisms. Microorganisms are those organisms that are too small to see with the naked eye and include things like bacteria, fungi, and viruses.

Microbiologists study these organisms using tools, like microscopes, genetics, and culturing. Microscopes allow scientists to magnify microbial cells that are otherwise too small to see. Genetics and molecular biology help scientists understand the evolutionary relationships between microbes and their habitats.

 

 

Our instruments:

 

1. Culturing is the term used to describe growing microbes, usually combined with tests to see what the microbes like to eat or what conditions they can live in. If you've ever seen a petri dish, you've seen a common place where microbes are cultivated.

 

2. Microscope

An optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.

 

3. water bath

A container of water heated to a given temperature, used for heating substances placed in smaller containers.

 

4. Incubator

 In biology, an incubator is a device used to grow and maintain microbiological cultures or cell cultures. The incubator maintains optimal temperature, humidity and other conditions such as the carbon dioxide (CO2) and oxygen content of the atmosphere inside. Incubators are essential for a lot of experimental work in cell biology, microbiology and molecular biology and are used to culture both bacterial as well as eukaryotic cells.

5. Laboratory ovens

Are ovens for high-forced volume thermal convection applications. These ovens generally provide uniform temperatures throughout. Process applications for laboratory ovens can be for annealing, die-bond curing, drying, Polyimide baking, sterilizing, and other industrial laboratory functions. Typical sizes are from one cubic foot to 0.9 cubic metres (32 cu ft) with temperatures that can be over 340 degrees Celsius.

6. Centrifuge

Is a process which involves the application of the centripetal force for the sedimentation of heterogeneous mixtures with a centrifuge, and is used in industrial and laboratory settings. This process is used to separate two immiscible substances. More-dense components of the mixture migrate away from the axis of the centrifuge, while less-dense components of the mixture migrate towards the axis. Chemists and biologists may increase the effective gravitational force on a test tube so as to more rapidly and completely cause the precipitate (pellet) to gather on the bottom of the tube. The remaining solution (supernatant) may be discarded with a pipette.

 

6. Heater

 A heating mantle  is a piece of laboratory equipment used to apply heat to containers, as an alternative to other forms of heated bath. 

7. Autoclave

Is a term used mainly in laboratories whilst 'Sterilizer' is used more commonly for medical and pharmaceutical applications. An effective Autoclave or Sterilizer must contain dry saturated steam.

 

 Advantage of Microbiology lab

 Our lab is ready for doing any under graduation and post graduation project or other research cooperation with other ministers

 

There are five areas for consideration when embarking on practical microbiology investigations which make planning ahead essential.

  •         Preparation and sterilization of equipment and culture media.
  •         Preparation of microbial cultures as stock culture for future investigations and inoculum for current investigation.
  •         Inoculation of the media with the prepared culture.
  •         Incubation of cultures and sampling during growth.
  •         Sterilization and safe disposal of all cultures and decontamination of all contaminated equipment.
  • Good organizational skills and a disciplined approach ensure that every activity is performed both safely and successfully.
