I made lemon juice 6 month ago.

  • I just washed the lemon using brush and then cut them into pieces.
  • Then I put one layer of lemon in the bottle followed by one layer of sugar
  • Again one layer of lemon and one layer of sugar.
  • Then I close the bottle and put it in the refrigerator.

When I opened it, I observed some pink colored mold on the lemon slices.

Can anyone can identify the mold or tell me how to identify it?

PS: in the 6 months, I never opened the bottle. The bottle was clean and I did not add water; just lemon and sugar.

    $\begingroup$ Whatever it is, I would not consume the lemon juice. The chances of toxins being present are just too high. $\endgroup$ – MattDMo Oct 27 '14 at 15:09
  • $\begingroup$ It can be Neurospora crassa....cause the fungus is pink, can live in anaerobic conditions, & can survive on carbohydrates, like sugar...but it's only a wild guess.... The pickle in your case got spoiled because it got in contact with water, only a few drops, but enough to cause those scattered microbial infections... $\endgroup$ – souvik bhattacharya Nov 18 '14 at 5:40

  • $\begingroup$ I would say that it is very hard to impossible to identify a mold simply by photos. There are a number of different molds that can grow under the actual conditions. $\endgroup$ – Chris Nov 18 '14 at 11:11

I checked citrus diseases on wikipedia, then "ctrl+f" and typed in "pink mold". The result was Gliocladium roseum which is really a pink mold, but it is hard to find any image of it, where it is on fruits... So this is just a guess. Btw. I think it is rarely possible to identify microorganisms just by checking an image of them.

  • $\begingroup$ citrus disease refers to mainly diseases on live citrus trees or fruits still on trees...the q is talking about a dead, refrigerated citrus... $\endgroup$ – souvik bhattacharya Nov 18 '14 at 5:39
  • $\begingroup$ @souvikbhattacharya "It colonizes living plants as an endophyte, digests material in soil as a saprophyte and is also known as a parasite of other fungi and of nematodes." - according to wikipedia. So I think it can survive on a dead lemon as well and likes anaerob conditions. Before cutting into slices the lemon was pretty alive (like every other fruit). The freezing not necessary kills microbes. Btw. I think it is impossible to find out what it is without laboratory tests... $\endgroup$ – inf3rno Nov 18 '14 at 6:33

    $\begingroup$ If the mold was already there before pickling it...then why pickle it in the 1st place???....neway the q is pretty frustrating...why don't she try it out to find what actually it is,"great 1st hand experience"..;) $\endgroup$ – souvik bhattacharya Nov 18 '14 at 8:13
