How well do disinfectants work? help my bacteria won't grow

Hi, I bought some agar powder on amazon, of which I read the reviews and someone said they used it to grow bacteria for a science fair project so I thought it would be fine. I have completed all the steps for this experiment and it has now been 2 days and there is no sign of bacterial growth. There does seem to be some lumps in the agar which I was unable to get out. Looking online, my agar plates look a little bit more yellowish coloured than others and I don't know if that's because of the type of agar or because it is mixed wrong. I am just wondering if this is the right type of agar to use. It's been stored at room temperature so this could also be a problem. I don't have time to really order from the US so I'm struggling a bit. Here is the link: http://www.amazon.co.uk/gp/aw/d/B00BWBB ... words=agar
