liquid culture question ??
    #9958026 - 03/12/09 12:25 PM (15 years, 10 days ago)

ok folks,
          i am trying my hand at making my first liquid culture.
i am gonna use the method in the link below.
http://www.shroomery.org/forums/showflat.php/Cat/0/Number/5238137/page/0/fpart/1/vc/1

my question is:
does liquid culture have to breathe, and if so could i modify the lid in such a way that i can do so ??

my reason for this question is because i do not feel comfortable with just the foil over the lid with the hole open. i feel this would leave the culture open to contam

please tell me what you think ??


--------------------
next time i order a pizza i'm gonna ask them to cut it into 6 slices instead of 8, because i was'nt fit for 8 the last time !!

I just double foil mine.. The first foil I wrap around the jar a little bit tighter then the second piece of foil. Seems to be working effectively.

Without an air supply of some sort the mycelium will grow some, then stall out due to lack of oxygen.

So you've got two options.  One is to provide for filtered gas exchange, the other is to inject flame sterilized air.

I do all my lids (grain jars, lc's, etc) the same basic way:



Injection port + tyvek glued down over an air hole.

Little bit extra work, but they're re-usable and no fuss.

You can suck in air through a flame (slowly) into a clean syringe, then inject that into the LC jar and shake/swirl well.

It seemed like I needed to inject 20-30cc of air into a pint sized jar to get any significant growth and it would only last 2-3 days then stop growing again.

I did some comparisons awhile back and came to the conclusion that "sugar in the raw" was the cheapest, easiest sugar that produced good results to use in an LC. 

So I'd recommend that over honey, although I'm sure some people would disagree.  The sugar in the raw produces little to no discoloration or sediment and the mycelium grows well in it :-D

Plus it's already premeasured for you, 1 packet of sugar per 1 cup of water.

LC needs gas exchange - a layer of tyvek on your jar will work fine.

FYI, inoculating a jar of LC with spores is a terrible way to go about making cultures. You have a pretty high chance of contamination and could waste a lot of time inoculating jars only to find out that they're growing mold instead of mushroom mycelium.

Don't get me wrong, LC made in this fashion will *work*, but there's a lot of potential for failure.

If you've got a pressure cooker and you're using grains, follow the tek for Grain LC in my signature.

i just did this for my first lc too two weeks ago. If you do it in a sterile env and first, you should be fine, i just have my sitting with one layer of foil and its been fine.

So when you glue the tyvek over the air hole, are you careful not to get the lc near the tyvek for fear of wicking in contams? I want to know! And that sugar in the raw recipe is cool.

I use a hole with polyfill in it. Do you think it's enough for gas exchange to avoid stalling growth?

Two words. micropore tape

Put a hole in the lid big enough for the needle. Put micropore tape over hole, put foil over the top of the jar, pressure cook/steam. Once it's cooled down, take the foil off the jar, and use an alcohol soaked cotton ball or paper towel and wipe down the micropore tape, then inject through that (with a flame sterilized/alcohol sterilized needle) and put a new piece of micropore tape right over top of the hole.

Check it in a few days you should see some growth


edit: Forgot to add, you can get micropore tape fuckin all over the place. Any walmart pharmacy or large grocery store will definately have it. Look for paper tape in the first aid section.

cheers for that info.

i'm making it from a syringe i knocked up a few days ago not the spore print.
i think i will go with the double foil until i can get my hands on some tyvec and then i shall try a another lc using the tyvec.

i have already a few cakes innoc'ed from the same syringe so if they grow ok ie: without contams. would that not be a sign that the lc should be ok ??

i love the sound of the micropore tape but also read somewhere on here that if it gets wet it is a magnet for contams ??

Any filter material (synthetic filter disc, polyfil, tyvek, micropore tape, vermiculite) that gets wet will wick in contaminants.

Here's how I make lid filters:

http://www.shroomery.org/forums/showflat.php/Number/9550279

As for the LC: 2g honey & 100ml water, PC at 15psi for 15 minutes. Let cool and inoculate through the injection port.

You can use polyfil lids, with coffee filter dust covers also. Just make sure to only make the Lc half the jar or 3/4 soo the myc doesnt start growing up the polyfil.

sometimes your jars can fall or tilt causing the lc to wet the gas exchange filter which is a troublemaker.

you can use tyvek polyfill micropore tape and if your broke, Coffee filter....

micropore is messy, the glue is messy and a hassle if you want to reuse your jars.

I made this a while back it works well, just follow the link 

Band-aids dont work well RR has said it many times and ive proved it with a contam, they dont last and dont breathe well.

Follow the link, its a light Karo tech but works great.
Good luck, and other questions PM me i have 7 diff strains goin right now in LC and can answer damn near any questions you have bout em...

Making injection ports is easy. You make a small hole in the lid, add a blob of silicone gel on both sides of the hole. Any silicone will do. It's not messy, it will self heal and you can re-use it as many times as you want.

I make injection ports to all my grain and LC jars. Also I use the 2-sided micropore filters, as described in the link I posted: as there are actually 2 filters, one on the inside & one on the outside, it doesn't matter if the one on the inside gets wet from the LC - the one on the outside will keep contams away until the inside filter dries.

I tried micropore tape, but I'm not a big fan of it.  It does work, but it's messy and has to be replaced.

So far (3 or 4 cycles) I haven't had to replace any tyvek patches.

In the states, you can get tyvec in any post office for free, but since your location says "Eire" you can be in either Ireland or Canada, so it may not apply. 

I also use tyvec.  It works nice!  :grin:
