LC question
#10248844 - 04/28/09 11:20 AM (14 years, 10 months ago) |

I have recently been trying to do an LC, but every time it has produced nothing but trich.....and I have been overkilling the sterile procedures. glovebox, TONS of instant hand sanitizer, scrubbing everything down with iso before using, etc.....anyways, the honey i've been using at 4% mixture seems to not break down entirely when i pressure cook it for an hour....it seems to leave a silty residue on the bottom. could i be using the wrong type of honey? if so, does anyone have a recommended brand?

You're pressure cooking too long, and the sugar is caramelizing... That's the silt.
Alot of ppl use Karo light corn syrup.

I've had great luck with the honey that comes in a plastic bear.

ah, i see; what's the recommended time that will sterilize it without caramelizing it?

It doesn't seem to matter to my myc if there is silt on the bottom, it eats it up and eats everything in the water until it's clear. I've used honey, and I've used dex/lme with better success, and seen the same thing happen...cloudy to clear.
But, yes, an hour is way too long to pc a liquid culture.
At what point in the process are you seeing contams?
What are you inoculating your LC with?
Are you flame sterilizing the needle if you are using one?
What kind of lids are you using?

Well either your WBS isn't sterilized thoroughly or you're tainting your LC when you add that piece of stem to it and my bet is that latter. Make sure your tissue is clean.....maybe do a H202 dunk and make the transfer as sterile as possible. Other than that just be sure your WBS is rinsed well b4 and after the soak and thoroughly PC'd. Maybe order up a syringe from a vender and inoculate your LC if you keep having trouble....you can't go wrong that way.

no, i know it's not my wbs; my spore syringes noc'd em up fine; and i do an alcohol wipe on the stem before biopsyin' it....is hydrogen pyroxide better to use to sterilize it?

Here is the link. Pure greatness http://www.shroomery.org/forums/showflat.php/Cat/0/Number/6817701/an/0/page/0
Although it would not do the cloning that you are wanting to do but seriously give it a read...
