Results

I waited 2 days after my experiment to check on the mould and see what had happened. There hasn't really been any real distinguishment, but I saw that the parts where the vinegar had touched there appeared to be some sort of white covering on the mould. I think that's a different type of mould that's grown on top of the main area. Anyways here are the photos:

Results of bag A:


Results of bag B:


Results of bag C:


Judging from the bags of mould that I'm looking at right now cos the photos aren't too reliable, it seems that bag B has been the most effective. Where the rice vinegar has touched the mould, a little patch of pale pink has grown on the mould and is almost the original colour of the bread. Bag C seems to be the second most effective. A pale pink patch where the mould was had grown, but the pink colour isn't as evident as it is in bag B. This might be due to the red colouring used in rice vinegar. Bag A, the bag with the brown vinegar, seemed to be the least effective. A pale yellow covering had grown on the mould but it didn't seem to have killed the mould as effectively as the other two vinegars had.
Therefore I can conclude that rice vinegar was the most effective in killing bread mould and that it has the highest concentration of acetic acid out of rice vinegar, white vinegar and brown vinegar.

Post experiment

Alright so I put the vinegar onto the bread mould and here's the photos. To keep track of it easier, I put it in alphabetical order so bag A was brown vinegar, bag B was rice vinegar and bag C was white vinegar.

Experiment !

I know it's been ages since I last posted and during that time, I experimented on my mould, and now I have the results. The experiment was on Friday, and I took some pictures before and after I dropped the vinegar onto the mould. Here they are:

Day 9

That is seriously ****ed. LOLL
All my other pieces of bread have started to mould, and my control variable is still nice and clean with no signs of mould starting. Nice, how am I supposed to do my experiment now ==
I think I'll just tear a bit of mould off each other piece of bread so that can be kept as a control instead of my current epic fail one.
I will most likely be starting my experiment sometime tomorrow or Friday. Hopefully all goes well x]

Day 7 !

I remember, it's day 7 ! I'm waiting for more mould to grow on my bread THEN start my experiment in a few days. There's not enough mould to start experimenting on..
I'll update with photos tomorrow. I'm too cold to get off my computer x]

Day 6? Day 7/?

Haha I really don't remember exactly which day I started my experiment. I can't be bothered to remember now, but don't worry, I will :)

YESS MOULD HAS STARTED GROWING
But on all the pieces of bread except the control. There's different colour moulds growing, I think one's Penicillium and the other Aspergillus? I'm not too sure, but hopefully that won't affect my results. Sighh
I'll start experimenting when the mould grows more and covers at least half the slice of bread. Hopefully that won't take too long (:

Day 4 and nothing's happening.

Gosh it's day 4 already and nothing's happening to my experiment. I just checked my bread, and nothing's a different colour. I guess I'll have to wait a few more days. Meanwhile, I'm getting started on my intro and abstract and working out how to graph results :)
