question about cloneing
    #1743088 - 07/24/03 12:23 AM (13 years, 7 months ago)

is it possible to do a clone by putting the small clean peace of "parent" mushroom right into a small container of steril grain rather then going to agar first ??  i cant do agar ... just cant do it :frown:  \
any tips
thanks
peace

yes that will work if you keep it sterile .
but i think its easier to grow it in a liquid culture first .
i use 1 tsp. karo, 8 oz. h20, let cool after sterilization, and inject 1 cc of 3% h2o2 . you can even dip the tissue sample in 3% h2o2 for a few sec. then drop it in .
i've done this without a glovebox with good results .

Yes, but it may take you a few tries.  Right before you transfer the clone tissue into the jars, squirt some hydrogen peroxide in there.  Fill some sterile syringes with peroxide and put about 5cc per pint jar.  Shake each jar very well and let them sit for a moment. 

This is a good time to pick the mushroom you are going to clone.  You might want to put it into a clean plastic bag or other container to bring it to your work area. 

Flame sterilize and/or wipe with alcohol a scalpel or sharp knife.  Shave off the outer layer of the stem near the bottom like you would cut a carrot into shavings.  Cut a few slices of the stem from this area and put the pieces into your jars.

Incubate and wait. :smile:

There is an exceedingly simple method of cloning at www.fungifun.org. Although on there it shows the clone tissue being placed into a petri dish of agar, you can certainly substitute any grain jar for that.

The only problem would be that it would grow pretty slowly this way, unless you could somehow distribute the cells throughout the grain. Otherwise, you'll have one site from where the cells will grow out. Remember to take a sterile piece from the inside, of course. I rub the outside of the fruitbody with 70% alcohol, but that's just me.

What problems are you having with agar?

Won't gell correctly is usually caused by one of the following:

1) weight of agar to volume of water is incorrect
2) agar not fully disolved into water
3) not using distilled water
4) sterilization temperature not correct
5) sterilization time not correct
6) using low grade agar

Dries out:

1) pour thicker plates
2) seal petri after innoculation
3) not used soon enough
4) using low grade agar

Contam:

1) improve technique
2) use flow hood or glove box  (skip the oven tek!!)
3) add antibiotics to agar mix
4) add sterile hydrogen peroxide to agar mix (after sterilization)

Will not support growth:

1) agar has dried out :smile:
2) using low grade agar
3) not adding proper nutrients to agar
4) too high temperature during sterilization causing carmalization


Remember, agar with nothing else added has very little nutritional value for whatever you are growing to consume.  You need to add sugars and starches to get things to grow.. PDA for example is agar with dextrose and potato starch added.
