Today, we continue our lecture on isolation ,culturing , maintaining and preserving microbes. First, we need know the definition of aseptic technique. Aseptic technique refers to carrying out a procedure under controlled condition in a manner that will minimize the chance of contamination.

Culturing methods have 2 basic technique which are liquid and qulture. Liquid can be reared in culture tubes in a liquid medium while qulture use plates where the liquid medium is solidified using agar and poured as a thin layer in the bottom of a culture dish.

Besides, we know how to get pure culture by using streak dilution plate methods.

this is how to obtain pure culture using pour plate method.

There are 5 type of culture media which are chemically defined vs. complex media, liquid vs. semisolid media, selective media, differential media and enrichment media.

Bacterial growth by budding, spores and fragmentation.

Till we met again, BYE! XD
