Best agar method

So I have light malt extract and agar. What's the best ratio. And what's best for making a mono culture out of; spore, clone, or lc. Guessing clone.

I use PDA so I cant really help you with LME ratios but I would say starting with a clone is the fastest way to an isolate.

my fave recipe:
22 grams agar 20 grams ME 1000 mL hot water
1. clones 2. T1 3. T2 4. T3 5. T4
You should have a monoculture by T4 or T5

That's a very rich recipe. Go 500ml water, 10g agar, 8-10 grams LME.

Am I the only one who streaks my plates? When you streak the spores across the plate the amount of spores deposited on the agar decreases as you progress down the streak. At the end of streak there are the least spores which means the least amount of strains produced in that area and the least amount of transfers required to get a monoculture. 5 transfers to get an isolate seems kind of excessive.

Yessir, I also enjoy a good streaked plate, old microbiology habit. Haven't started enough spores on plates to see how well it works for isolating but it's certainly a fine thing for germinating.

I prefer to fruit bulk MS, then take clones from the healthiest, best-looking clumps (1st flush). Starting from MS on plates is fine, too tho, yeah... I agree with you.
I always assume newbies need more transfers away from contamination and tend to transfer larger pieces... 5 transfers is definitely too many, but I think they'll find success by then. Assuming they transfer as soon as new growth appears they shouldn't wear the mycelium out.. right?

i rarely see sectoring before 4 transfers from spores

What? I usually see sectoring on 1st transfer from my spore plate.

you may see some sorta sectoring but not real strong sectoring that makes isolating easier

I got shit all lucky with my last sleeve and had strong rhizomorphic growth on a spore germination plate. Like at the point of germination and could identify a sector by the time it neared the edge of the plate.(gave me a good place to start anywho)
Made my job a lot shorter.

I don't even bother with strain isolation normally and streak mainly for the purpose of making it easier to spot and isolate mycelium from any contaminants in the spores. If I was intent on getting a monoculture though I believe that's the fastest way.

That's basically the point I was trying to make. You can see sectoring on the first plate when you streak.

I've taken to using a bread tie as my inoc loop.
Strip it down to just wire and either touch the very tip to agar, then the outside lightest ring of a print or lay it down and use it that way.

i always streak but am yet to get a mono culure that fast mind you i've been doing alot more cloning these days then isolating

i cool loop/blade in receiving plate, and gently, lightly touch/dab the print (instead of swiping/streaking the print) and swipe one line back in receiving plate. ill do three lines, 1/2" apart, 1" long about, for same reason kizzle streaks. def can see sectoring by plate 4 some times even by plate two, u can begin to see where it would begin to sector if left to grow

Next time you go from print, try using the tiniest point you can find. Ie: needle point, teeny tiny paperclip, bread tie, etc. It drastically cuts down on the amount of plates you go through.
