Hello everyone
I am making 2% malt agar plates by adding 7.5g agar and 10g malt extract in 500ml of DI water. I want to bring the pH of the media to 5 and for that, I would be using a buffer of 0.1M sodium acetate and 0 .1M acetic acid diluted to 200ml using dI water. I want to know if I should make the agar media first say 300ml and then pour the buffer, adjust the pH and then autoclave or I should just make the entire media in a buffer (500ml), adjust the pH and autoclave..?
