    Well the answer to the question is: the E.coli ( or other infectious microorganisms can be analyzed better in open system) because our body acts like an open system where nutrients are provided under aerobic conditions ( moreover E.coli growth rate can be analyzed optimally under aerobic conditions) so the answer would be : open systems

    I dont get how you can report the results in ug/ml when it is a dry strip. you have a certain ug of drug on the disk but there is no liquid so how can it be reported in ug/ml?

    That's it?? Why don't you explain, in detail, how science "grows" a virus particle in a cell culture and proves that it actually exists? That's why I clicked on this "cultivating viruses" video.

  • @sarekaya4815
    @sarekaya4815 Год назад

    I tried this method, but the bacteria did not grow as colonies, they grew in the whole plate and I could not count the colonies. What is the reason? thanks

    • @fukyoutubestupidfuckinghandles
      @fukyoutubestupidfuckinghandles Год назад

      This method covered the whole plate so that's how it grew. This method isn't for counting colonies.

    • @fukyoutubestupidfuckinghandles
      @fukyoutubestupidfuckinghandles Год назад

      streak plate method might be better but ive just started so there's probably a better method i dont know

    • @ashlykraphy9933
      @ashlykraphy9933 Год назад

      Sare kaya, You probably need to dilute the sample more so that you get it in countable range which is 20-200 for spread plating technique.
