Agar Preperation

#2263387 - 01/23/04 02:05 AM (19 years, 18 days ago)

I have got my hands on some nutritive yeast, malt extract and agar. My question is all the formulas list ingredients per gram.. i dont have a gram scale, so does anyone know what it works out into teaspoons or whatever? a measurement for all ingredients in mL would be greatly appreciated! Thanks guys :shiftyeyes:

heh usually from what i've heard...a teaspoon is about 3grams...but youknow density matters and all that. *shrug* you can buy a cheap gram scale that is somewhat accurate for around 20$ at your local headshop.

I went and measured some agar powder from sporeworks:

10 ml powder(loose) is 5.2 grams.

I don?t have any malt extract here.

Yeast is used like a pinch for 100 ml water.

I just measured out and weighed my malt extract powder three different times. Scooped up 1 teaspoon full, shook level (or used back of knife to level), and the average of those three was 1 teaspoon = approx. 3 grams...

You can streak them or use spore water. Streaking will result in a conglomerated mess of substrains. The more substrains you use to inoculate, the better your chance of a successful fruiting. If you are inoculating grain without isolating, this is probably the way to go.

If you wanted to isolate substrains before you fruit, use diluted spore water. You can dilute it enough that you can get as few as 5 substrains out of a few drops. Spore dilutions are better for agar isolation.
