srp

ok so i have actually started my srp, but it didn't go very well.. i left the petri films in the incubator for too long. i started on sunday at 9.15 pm, and its still in there. oh well. i just wanted to say that i had a look at them, and there are distinct bacteria colonies by the third dilution, like, you don't even need a microscope to see them. so i'm thinking of leaving it a 5 dilutions.

and i didn't use water to dilute the milk, i used this pre-made diluent that comes with the test tubes. its 1mL of the diluent and 0.25mL of full cream milk in the first test tube, in the second its like 1mL of diluent and 0.25mL of the first dilution and so on.

so im going to start my srp again tonight, lets hope this goes well.
