I've always wanted to try to get agar straight from the seaweed. Just because I think it would be cool, if not economically sound (I pay about 75 cents for 25 grams, on sale, less than $1 normally)

This is a great write-up! Keep us posted!

Thought I was gonna chew out Agar didn't you? Fooled you didn't I?

WTF am I supposed to do with this?







i got something like that from a local japanese food retailer.
£1.10 for 30g.
i used about 10g in something like 3/4 pint boiled it up to dissolve with a spoonful of golden syrup,smelt lovely, a few fresh black-berry's,make a fool type desert...anyway...
cooked it up and tested it's gelling properties by dropping on a cold plate.when it got to the consistency i imagined useful,never worked with agar before so had to guess,pc'd for 20+mins in a clean ketchup bottle for ease of pouring.
not really done much with it yet as i am finding it hard to source an affordable supply of petri's,bugetary constraints and all...

i still have this bottle in the fridge about two months later,anyone know how long this would remain usable,or, how many times you could reheat this stuff ?
sorry for the non-scientific description.

You should be able to get really cheap packs of petri dishes from eBay so long as you go for the plastic kind. The ones I got were polystyrene or ester I think, which means autoclaving isn't a great idea, but they stood up to the heat of having literally boiling agar poured into them no problems!

It's not so bad using plastic dishes either. Unless you're doing a lot of work, a 20 pack of plates should last you a good while.

If you haven't added any nutrient to your agar, it should last quite a long time. If it's sterilised and stored cold there's no real reason for it to go off. I'm not sure if you can freeze agar and still use it though.

Consistency wise, you want a firm gel as opposed to something your finger squishes through when poked. Although, provided you're careful with handling, a liquid type gel would work as well. The benefit of having a firmer gel that stays stuck to the plate is that you can flip the plates over after pouring and during incubation so any moisture runs off the sample and into the lid. If you don't do that, you can end up with a puddle on the plate... uncool.

Just in case you're interested, I did a quick google and apparently agar can be turned into a foam by freeze drying, which can then be used for biodegradable packaging.... :grin:

I often make my agar pretty soft. From 2% all the way down to 1.5%. The gelling strength of your agar will come into play, so don't make some 1.5% and then curse me if it doesn't gell well enough. I've never had any problems turning dishes upside down. Just make sure that it's solid. But you can make it anywhere from very soft to very hard and still have good luck IME.

The advantages to using weaker concentrations IME are to save agar and softer agar seems to let spores embed down into it easier. If your agar is too strong I've found that the surface will dry pretty quickly sometimes and spores will just sit on top of it without getting embedded enough to absorb enough moisture.
