Advice needed - not getting anywhere
#27067925 - 12/02/20 10:11 AM (3 years, 2 months ago) |

Greetings, I'm on my 5th attempt and thus far nothing has worked.
1st and 2nd attempts were with BRF cakes in 200ml jars. Mix was correct at 2:1:1 ratio. Pressure cooked at 15psi for 90min. inoculated with spore syringe inside a SAB. Temp was around 20-24C. Nothing happened for about 3 weeks. Then some white spots that stopped growing after 2 weeks. Shook the jars but nothing happed and in the end it grew mold.
Attempts 3,4 and 5 I got new syringes, made Agar which I left for a week to make sure it was still clean. inoculated the agar plates and once they were grown out I swithed to 500ml oats jars (boiled then simmered for 45min) air dried for 24hours then pressure cooked at 15psi for 90min.
It's been 3 weeks now and the oats jars started off well enough and once they got to about 30% I shook them. Again as previously the white growth spots are gone and what is their now is more gray with a gray milky discharge. Nothing looks what I have seen here or elsewhere online.
Any advice or ideas would be appreciated

If you have gotten clean cultures on agar then it sounds like the common issue is your sterilization process. What kind of PC are you using? Are you venting it properly?

Both your BRF jar and your grain jars look really wet to me. If too wet it can stall out your myc and promote contams.

Don't shake BRF cakes. The top verm layer acts as a barrier. What do the tops of your lids look like?

Those oat jars are prepared incorrectly. They're far too wet

No idea what make it is but it's probably 30 years old. Doesn't have a weight on but a plug that extends upwards with marks denoting pressure.

The BRF jars haven't been shaken at all and I wasn't planning to either. The lids have 4 holes in were the syringe went thru.

These 4 are 12 days old now.

I was thinking the same thing but they were placed on the stove, brought up to boiling then back down to a simmer for 50min if I recall correctly. I left then for almost a full 24 hour spread out to cool off/dry before bottling them. At the time none clinged to my hands and their was a very few wet spots to nothing on the hand towels when i tested them.
I was thinking on throwing these out tomorrow and trying again to soak them for 24hours instead of using the stove...but I honestly don't know what I could be doing wrong.
Thinking on it now they look fine for about 2 weeks and it's usually around then perhaps 3 when I start noticing water building up on the bottom.

The BRF mix 2:1:1 i used the same coffee cup to measure everything so I can't see how I used to much water. Looking the the 4 jars bottoms I don't see the same water build-up as with the oats jars. I opened 1 jars lid and it smells kind of sour.

a mere 100-200ml can throw off a brf jar easy.

Your original post says you shook jar

Additionally if those are your grain jar lids they need filter. Where are you storing those jars during colonization?

You can have a perfect mix to start out, but depending on how deep the water is in your PC, and how you wrap them with foil, they can take on water during sterilization. I’ve had BRF jars come out saturated before.

What I see: -jars too wet -No visible holes for Gas Exchange. Conclusion: You need to properly vent your jars by adding punctures to the lids for Gas exchange. EDIT: I didn't see the fifth pic you posted showing punctured lids. New Conclusion: Your sterilization process is off, somehow there is moisture entering your jars during the PC cycle causing over hydration and subsequent contamination. Possible point of contamination could be not using proper filters on your lids like Micropore tape or fiber disks. One layer of Micropore tape over your holes will suffice if nothing else.

The holes are covered by micropore tape. Everything is kept in a spare bedroom. Well lit but no direct sunlight. The temp is between 21C - 28C

No, you want the hulls intact like in the pic. They look so wet and mushy in the OP that I thought for a moment they could be hulled oats.

I fill the PC with about an inch of water. If more it doesn't come past the bottom 1cm of the jars. All holes are micropore taped and then covered with foil. I don't recall ever noting the micropore tape being wet when removing the foil or seeing water on the lid under the foil either but I'll take special note on the next round

Ah so you're adding your micropore tape on and then PCing the jars. There I believe is your issue. You need to PC without micropore and add it to the jars at the time of inoculation.

Ok I'll try that on the next batch. I use micropore tape since I couldn't find polyfill easily. But from what I've seen lids with polyfill are PC'd with them in so how can micropore closed holes make such a big difference?
I used my last bit of Agar to make some LC since Im still waiting on another batch of sterilised petri dishes. The syringes I received are 10ml in size with 8ml LC. How much LC per hole on the oat jars? 1ml/2ml For the 200ml BRF jars with 4 holes? 1ml/2ml I recall using 1ml per hole since I used a 8ml for 2 jars
