Microbiology Lab Bacterial Culture Techniques

Microbiology Lab Bacterial Culture Techniques Flame the loop and cool it in the agar. overlap the step 1 streak 3 4 times to pull out a reduced number of bacteria, and spread them out down the side of the plate. consider this step 2. flame the loop and cool it in the agar. overlap the step 2 streak 3 4 times and spread over the surface. Pay attention to what you are doing at all times! aseptic techniques include the following practices: 1. minimize the time that cultures and growth media are open to the environment. 2. disinfect the work area before and after use. 3. do not touch or breathe into the sterile culture media or the stock cultures.

Introduction To Microbiology Culture Techniques Youtube When transferring a broth culture, aseptically withdraw approxi mately 1.0 ml of the culture and transfer into 5 ml of fresh broth, or transfer several drops of the suspension to an agar slant or plate. when transferring a culture from an agar slant, aseptically transfer a single colony to 5 ml of fresh broth or to an agar slant or plate. Aseptically remove the swab from its container. unless the source itself is moist, wet the swab as follows. take a tube of sterile water in the left hand, open the lid, carefully insert the swab into the water and press against the wall of the tube to squeeze out excess water. the swab should be damp and not soggy. 2. label the bottom of each of the 3 prepared nutrient agar plate with your name or initials, your lab section, and the bacterial species to be used. in addition, label one "from broth", one "from agar", and one "mixed culture". 3. use the aseptic techniques you learned in part b. sterilize the loop and allow it to cool. When working in a microbiology laboratory, you must always remember that bacteria are present on all surfaces in the lab, as well as on your own hands and clothing. aseptic techniques are designed to prevent the transfer of bacteria from the surrounding environment into a culture medium and from a culture to the environment.

A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology. the term culture can also refer to the. Abstract. this chapter introduces microbiology and basic techniques in microbiology. it gives overview of the techniques involved in culturing microorganism, including preparation and sterilization of culture media and isolation of pure cultures by aseptic techniques using the streaking method, pour plate, spread plate, and subculture techniques.
