 black specks in colonizing jars 
#982268 - 10/22/02 10:22 AM (18 years, 11 months ago) |

In my last set of 1/2 pints (brf + rye flour) I chucked a jar that was showing black specks. Now my latest set of jars (brf + millet) is showing small black specks, some slightly rod-shaped, within the white beginning areas of colonization only.
Most likely to me would be clumped spores, since it only appears in colonizing areas...wouldn't a contam attack the uncolonized substrate first?
All opinions appreciated. Peace!

It does not sound good but don't do anything rash. Separate the black speck jars from the others and wait. If it is a contam you'll know in a few days. Good luck.

He didn't say if he was using verm or not all he said was brf+rye and brf+millet. Do what dog said, seperate and wait. BTW, its interesting that you used brf in conjunction with millet and rye, both are usually used by themselves, not saying that you did anything wrong, I just haven't heard all that much about combining them. Out of curiosity, how did you sterilize these jars? Good luck.

Thanks all for input.
The jars are PF formula, verm + brf, but then I've also tried adulterating the brf portion by say 25-40% with other grains just to see how they affect growth rate. The batch with some rye flour mixed in seems to be colonizing slightly quicker than usual. The millet I hope will provide more sustained nutrition over time.
I sterilize by boiling the jars in a large stock pot, washcloth on the bottom, and water about half way up the jar sides. Previously I heated them for 1-1/2 hours, this time about 1-1/4 hours.
A few minutes ago, I went back and checked the remaining syringes and they're super clumpy in there...I think that's my answer. When I did the jars (they are all displaying the specks), despite shaking, the inoculant was rather clumped, and the areas now starting to colonize provide a white background for spotting the clumped spores. I think that the fact the specks are only appearing in colonized areas is the key. And they look more like black pepper, rather than fuzzy or blotchy spots.
Guess we'll see. Thanks again for all your help.

If you sterilized your grain by boiling, then it may very likely be contams, grain is harder to sterilize than BRF, and almost always needs to be sterilized using a PC. Well, hopefully, somehow, maybe you will get lucky, but next time you may want to try PC'ing your grain. Good Luck

Thanks for all your help.
The mycelium are ripping thru those jars right now like Sherman thru Atlanta.
Methinks that millet kernels being so small and dry might get sterilized enough through boiling, but I defer to others more experienced.
Peace & goos luck!

I am having the same problem. I inoculated pint jars and it is taking forever to colonize. Just read that 1/2 pint is the way to go for cakes. I also forgot to shake syringe. I am curious! One has a black spot that has been there for weeks but the spot has barely grown. My most active jar by the way. If it does not grow is it still a contam or bacteria?

IME, the black "rod" shaped specs are just clumps of dried spores. I just used a syringe that I made myself that had the "rods" in it. Also I have noticed that if you use a lighter or candle to flame sterilize, sometimes the soot comes off in the jars and that also makes black spots.
EDIT: I meant to say the if you use a lighter or candle to flame sterilize sometimes black soot comes off in the jars.
