What Are Some Advantages And Disadvantages Of The Serial Dilution Agar Plate Te

A specific amount of bacteria are reduced with every dilution. Ivms 4200 client default password. The number of colonies cultured from serial dilutions of the sample are counted to estimate the concentration of an unknown sample. Then back track the measured counts to the unknown concentration. It does not separate bacteria like a streak plate.

Here's a paragraph about the molds that may help to infer the reason of the advantages during observation of mold colonies: 'Because the structural components of molds are very delicate, even simple handling with an inoculating loop may result in mechanical disruption of their components.The followi ng culture technique es used to to avoid this disruption. After culturing, molds spores are deposited in the surface of the agar and incubated in a moist chamber at room temperature. Direct microscopic observation is then possible without fear of disruption or damage to the anatomical components'. It may be more beneficial in this aspect: allowing a full and healthy growth of the mold, that is, with its complete structure, then to be able to proceed to look through the microscope maybe it form, type of spore,sporangia or mycelium. In short, ensure that the mold to grow properly. Maybe it's not what you exactly were looking for but it could help you! Second Year of Microbiology bachelor's degree (University Of Puerto Rico in Arecibo) Paragraph taken of Capuccino/Sherman Microbiology.

A laboratory Manual.Eight Edition. The following are some advantages of an agar plate verses a slant tube: 1. Surface area- An agar plate has a much larger surface area: a. Easier to isolate individual colonies using the streak-plate method.

Evaluate the colony shape, margin and elevation. Can grow a larger number of ce lls. Growth- An agar plate allows you to quantify the number of colonies on an agar plate, provided it is within the 30-300 range. Pioneer avic hd1bt update.

Whereas the slant tube cannot quantify growth but only describes growth as none, slight, moderate, or large.

According to the video on the proper aseptic techniques for use in a laboratory, one reason that aseptic technique is necessary is to protect oneself from contact with biohazards that exist within a lab setting. Additionally, it serves the purpose to protect samples from being contaminated. Aseptic technique is also extremely important for safeguarding others in the lab. Since bacteria are everywhere, including on all of the lab equipment, aseptic techniques allow us to avoid the spread of infection in the above ways. The concentration of bleach that is used to disinfect your work area is a 10% concentration of bleach. The bleach concentration serves as a disinfectant, which is an agent that is intended to kill or remove microorganisms, but it does not kill bacteria spores. It is not a method of sterilization because sterilization is the process used to remove all life forms, including bacteria spores.
