How to Tell if Your Lc is Contaminated

here is a phot of a contamed lc compared to a clean one. Of course the clean one has a shit load of mycelium in it. The one that is contaminated was inoculated 3 days ago so there is not much mycelium growth. I know what happened. I used a new scalpel and the chunk of mycelium that i was trying to drop into the jar would not fall off the blade. I had to hit the scalpel on the side of the jar to get the mycelium to fall off. By doing this I knocked loose something bad that was stuck on the scalpel up higher that was not killed by the alcohol bath.
BTW, the one on the right is bad. it is hazy,

Is the yellow one bad? Or the one on the right?
What LC process did you use?

The one on the left is the clean one and it sounds like he cut a piece of a mushroom off under a flowhood and dropped it in the jar. Don't quote me on it though ^_^

No way, dude. Can't you see the chunks of dark colored shit floating around in the yellow one? Anything dark is bad. The right one is clean.

the flash fucks up the color a bit. The one on the right is bad. The left is clean and full of mycelium

Yeah, okay, I see it now. It's not dark spots, it's just areas without mycelium.

Man, I don't mean to be attacking you Tahoe but that LC looks really poor....
and the yellow one, yea, obviously if your liquid culture turns a different shade then before you innoc it is bad but there is no way to tell if a LC is good or not until you inoculate a tester jar.
Listen guys, when it comes to a liquid culture ALWAYS innoc a tester jar before doing your final jar innoc's

what?? Say again in english. Maybe use a few periods.
As for not looking good. Please show me one that looks better. I did also mention that the color came out bad because of the flash

Color? I have made LC's that looked like straight piss and they were fine. The longer you cook a sugar based substance, the more likely it will turn yellow. Malt extact gives a yellow LC, so does corn syrup.
But I have had nearly clear LC's with honey, I didn't PC it as long though. I have had them go both ways, turned out fine.

I deleted that post because Samurai_Jim beat me to it. It wasn’t directed toward you anyway.
However, I said nothing about haziness so I don’t even know what you’re referring to.
An LC can be dark and still be clear.

+1 No disagreement here. Have you ever done a LC with the Potatoe water / dextrose? In my thread over there, you can see the LC after 5 days. It had potatoe particulate in the water. But I have done others that were clear as a bell.

Thanks for the comparison, I appreciate that as I have a couple LC's going and am very paranoid about the contam. I had three batches that were likely to have been perfectly fine but threw them away out of paranoia.
We'll know soon enough.

not to hijack your thread tahoe. but this was my attempt at cloning by dropping a couple core samples into an lc medium which was karo based (probably to much karo. 4% I'm pretty sure)
how does this look? does it look like mycelium or just the cores deteriorating to you guys?
the solid looking parts in there are the cores but they are getting all whispy and stringy around them. oh and i dropped the cores in there on the 15th

it is good enough to use now but let it grow for another week, about twice that much mycelium before you fridge it.
My lc's get so that that when I use them a layer of mycelium lays on top of the grain after injection. The finer mycelium runs down into the grain with the liquid. If I do not shake there will be a visible white lump after a few hours. I will take a pic of this tomorrow if i remeber. I have 4 jars reay to be inoculated and I am tired and going skiing tomorrow

so using this criteria your LC should be good:
- The liquid be the same color be the same as after cooked. - The liquid should not be cloudy. - The mycillium should be making ropey formations in the liquid.
Anything I missed on assessing your LC?
As well if your culture looks like this is a test culture necessary? I want to inoculate right away so any time savers? Also while on the topic what thickness should mycillium be in an LC before it is used?
