bacteria blues
    #23515549 - 08/06/16 10:00 AM (7 years, 5 months ago)

I've been having bacteria problems characterized by stalled jars, rotten fruit smell, and weak mycelia. i use pf tec on small jelly jars w masking tape. i sterilize my needles w a propane blowtorch between jars. frankly, im at a loss. at times the method is almost flawless, on other occasions, bacteria is rampant(80%). id really appreciate any suggestions to prevent this.    Would H2o2 in the syringe or jar work?

H2o2 would hurt. It damages mycelium helping contamination out.

Pictures or explanation of everything start to finish would help

Agar for syringe cleanup. Every project should be started on agar anyways. Also why masking tape? How permeable is it? You need a dry verm layer. That's it. No tape necessary.

Yeah, give us a detailed guide of your sterile tek, spawn prep, and inoculation. Procedure.    We can help you out but we need more information.

No pics needed then.    Just write out your process.

1 part brf, 2parts verm, 1 part water in 1/2 cup mason jelly jars inoculated at 4 points (old school PF tec) with a dry verm barrier....pc-ed at 15 psi for for 1hr plus and knocked up as soon as cool. i use a propane blow torch to flame sterilize between jar innoculations

Then explain your inoc procedure. Please tell me you don't use alcohol to wipe your needle.

I'm not asking for your sub ratios.    I'm asking for a detailed list that tells me your inoculation and sterile tek process. 

Can't help you figure out contam vectors if you do not provide this info.

Keep foil on lids or keep foil off after inoculation
We mean details

i use hand sanitizer,blue nitril gloves and a dustmask to innoc, pull the tape back, shoot em up, and cover back up. i leave the jars in a box in the closet till colonized. no finger fucking the jars. checked once every 4-5 days. i dont really mess w the temperature, my closet stays at about 75-78 degrees

Are you inoculating in open air?    This is a contam vector. 


You are innoculating directly from spores to grain.  This is also a contamination vector.  To remove this vector, inoc to agar, then do agar transfers if necessary (most times it's not necessary) and inoc with agar wedge.

Also, 9 times out of 10 when you have bacteria, it's already in your spawn before even inoculating.      PCING for 1 he isn't long enough.    PC for 90 mins minimum.    Use foil over the lid to prevent anything falling onto it, and try inoculating in a still air box or in front of a flow hood.

This is pf tek. No grains and no wedges.

Open air, although isn't ideal, won't be the reason why mass amounts of pf jars are going bacterial. Pf tek sterile tek is balls easy. If you don't alcohol wipe the needle, and flame between each jar, the problem is the syringe itself. Agar clean up and inoculating with LI would be the fix. Besides every project should be started on agar anyways.

yes, open air. I've not advanced to agar yet... no flow hood.(working on it)... im a poor man, this is a hobby, not business... but im advancing slowly. i do bleach and clean everything surreptitiously

Inoculate in a still air box. Keep your jars on a shelf with ambient light not in a box in a closet

PC for 1 hour is fine for cakes.

The last thing you need is a flow hood. Build a SAB

A $5 tote with arm holes cut out is all you need for agar and cake inoc.

Ah, missed the pf tek part.  The above info I gave is for grains, but sterility process still holds true.

why have so many people, lately, been thinking they need a flow hood to do agar work?

OP, SAB works perfectly fine for agar work, and everything else.

does light affect colonization rates??????????

i think i have heard a few poepel say that it does. regardless of whether it speeds colonization or not, light is beneficial at all stages of growth. mushrooms have a circadian similar to humans.

this is why we dont colonize in total darkness anymore. that was silly

really?... i tried and failed. it was a miserably hard xperience anyway. i felt like a moon man working with nuclear waste tied down to a table sweating my hands off. i am trying to build a flow box when my filter gets here, but im still waiting

It's harder to use a FH. If you can't get it down in a SAB a FH isn't going to be of any help.

If the SAB was too confined you just didn't build it big and wide enough for yourself

This is correct.  You want low level light during colonization. 

I've repeated this experiment a few thousand times now.  The colonizing bags in our mushroom farm near the north facing window grow at least 1/3 faster than those in the areas where it's darker.  Also, substrates colonizing near the isle where light penetrates colonize faster.

With most species you can inoculate agar and then stack two dishes on top of each other.  The top one will nearly always colonize faster than the bottom one.

What you don't want is very bright light during colonization which not only slows down growth but also could lead to premature fruiting.

hmm im so glad you posted that RR quote, Mad! i wonder if maybe these last 12 jars i did with my GT clone all started pinning in-vitro so early because they had too much direct light..

the light isnt literally directly on them, but i would say its probably more than what you would want when you hear "indirect/ambient light".

going to need to get them a little farther away.
