How often should you flame your loop when doing the streak plate technique don t need to flame the loop at all O only once before you make the 1st streak O only once before you make the last streak before making each streak and after you are done twice once before making the 1st streak and once after making the last streak

Why do we flame the tool loop before and after obtaining the bacteria Prevents the bacteria we obtained from contaminating our lab eg our lab table and anything on the table Prevents both microbes from the environment already on the tool from contaminating the experiment and bacteria we got from the tube from contaminating the lab Prevents microbes from the environment already on the tool from contaminating our experiment Heating the tool warms up the tool and this helps the bacteria we obtain to multiply better Heating the tool helps the bacteria to stick better to the tool and makes it easier for us to get the bacteria
