Slight discoloration on substrate

These photos are the bottom of a BRF jar. In the middle, in the uncolonized part, there seems to be a slight greenish-blue discoloration.


Is this jar a goner? My jars have been dropping out one by one over the last few weeks. This one is the farthest along of the remaining three and it would kill me to lose it at this point. Would there be any point in birthing it now and removing the uncolonized portion?

Looks like wetspot bacteria. How long since inoculation? RR

It was inoculated on May 20th, so 19 days.

After reading this thread, I decided to try and save my jar. I cut out the offending portions of the cake, as well as some extra to be safe. Then I dunked it overnight in the fridge. This morning I rolled it in dry verm and put it into a coke bottle terrarium. Here are two pics of it from different angles:


Does it look at all good? Did I overdo it with the dry verm roll?

Hi EWalter69, perharps you save your cake. perhaps! contaminants are very hard to kill over the spawn, quite impossible.
when you've extracted the cake from the jar, the upper part seems quite dry? if you you've done the right job dunking it, but the lower part, i believe that were bacteria. in italy we call it "pisciazza batterica" ( (bacteric pee!) Generally bacteria arrives when there's ah high amount of water, heat and no oxygenation (in fact the lower part is generically nearer to the heater, and of course the part with more moisture and less oxygenation)
remember next time to set better the moisture tax. or you've set the right tax but during the pressure cooking you'd have used too much high water level and water entered in jars...for this you should use a water level until (maximum) the half of the jars.
