If you made LC without a PC, it's not very likely to be clean :frown:





Actually, the ingredients we use for LC are not filled with different types of endospores and such, so we don't have to pressure cook liquid cultures. A simple 30 min. boil will do. :smile:



If ingredients are exposed to air at anytime during the process, prior to sterilization, then they have been exposed to endospores.




What about pf-tek jars? they get exposed to open air when you mix verm and brf.
they still do fine without a pc..

PF jars are pasteurized, A process that leaves behind beneficial bacteria which battles the trich for you

You can steam sterilize but, it takes about a week to kill all the endospores. They have to germinate to be killed.

You don't have to reach temps of 250 to sterilize. Killing endospores requires these high temps and grains are usually heavily laden with them and that is why we have to pc them. Things like brf and verm aren't full of endospores therefore they don't require those high temps for sterilization

brf+verm is mixed in open air. they do get sterilized by steaming in a pot.
if your statement was true pf-tek would need a pc too, wouldn't it?

it takes 8 hrs to steam grains in a normal pot.

Back to the original question
Here is a LC that looks very similar to yours

Made with LME & Dextrose which caramelized a bit in the PC
It tests clean, so as previously stated, "You gotta throw some on grain to know for sure" :goodluck:

Knocked up some BRF today, what I discovered was that the mycilium gets stuck in the syringe when trying to suck it up (18 gauge needle), I couldn't! had to take water from around it - I did do 4 new LC's last weekend and was pleased to see the two new GT jars both producing MC in 5 days. So I used those for the inoculation, and did 1 using that old GT in the original pics as a test.

So I guess one question: is the MC spread throughout the whole jar, or can you miss it if not stuck into the MC cloud?

Another issue that I realized is if you are sucking up 8-10 CC for a few jars of BRF, your supply runs out fairly quick...so I'm going to make a bigger jar of LC, also tipping the jar to reach the water is a bit disconcerting...

When mixing the VErm with water 2:1, I found quite a bit of water came out when I squeezed a handful, so I add more Verm, was still a problem, but then I was wondering if I wasn't squeezing it too hard, first time, so not sure if it was ok or not. It seemed fine after adding the BRF.

Put a marble or a piece of broken glass in your LC jug, this will help, when shaking the jar, to break up the mycelium mass when ready for use.
If you don't get a little of the white stuff in each item you knock up, it is possible that nothing will grow. I've had it happen on grain and petri dishes.
Go to a 14 gauge needle if you can, at least 16 gauge for LCs as 18s clog very easy.

I use a heavy duty inoculation port, an 18 gauge needle with a .02 micron Whatman syringe filter for GE. Then draw the cultures with a separate 14g or 16g
I have a magnetic stir plate so I now use that to break up the myc. Before that I was able to shake these jars with a marble in it without wetting the filter(bacteria swims right through a wet GE filter)

Thanks Skippy. Most of my jars are growing after 2 days, a few had nothing so I re-shot them with MC, checked the syringe before to make sure I could see bits floating around it.

Is that a homemade port there in the picture? Haven't seen one like that.

I was planning to do bulk from the BRF cakes, any suggestions on a tek to follow? I was going to try Coir/Verm...
