Call for yeast strains

[Thomas]

With the club purchase of new screw cap tubes, and an unexpected acquisition of a full box of screw cap tube from an old laboratory, we now have room for many more new strains of yeast. If anyone has a jar of washed yeast they would like to contribute to the library please let me know. You can either bring the yeast to the next club meeting, or I can pick it up/ you drop it off at your convenience.
And, as always, if any paid club members request a yeast slant please feel free to send me a PM. Otherwise, I will bring slants of all available strains to each meeting to be made available to all members.

I have these washed yeasts in my fridge at the moment:
1762 - Belgian Abbey II
3463 - Forbidden Fruit
3522 - Ardennes
2206 - Bavarian lager
3068 - Weihenstephan

I'm passing buy fredericton in 2 weeks so I could make a stop

Awesome collection!

I also have:
1728 Scottish
1099 Whitebread

I'll bring them to the meeting on Saturday...

[Thomas]

wow, that is an impressive collection Jamie! It would be greatly appreciated if you would like to donate any strains to the library.

[jamie_savoie]

Thomas, I will contact you back in about 10 days to confirm if I'm going.  

Also, I have 4184 - Sweet Mead in hand.  Will give a brand new smack pack too.  I bought 3 smack pack last october and only used 1 so far....

edit: and also have 1056 but most likely it's something you already have

[Kyle]

thanks guys. We do already have the 1056

[Jake]

I have washed California lager.

I also have smack packs of ringwood and ESB that I'll be using here shortly. So that'll be washed within next month

[Kyle]

I'll bring our additional 125 Autoclavable test tubes  

[Chris Craig]

That reminds me...I have 2 tubes to return...

[Richard]

Bring 'em today; if Thomas isn't there I'll make sure they get back to him.

[Chris Craig]

Yup

Hi
just curious does any one have a slant or mason jar of the 3068 Weihenstephan Weizen yeast to share?

Thanks

[Thomas]

So after an hiatus from curating the yeast collection, I am now back in action and slanting away. Some strains I had trouble trying to purify (1099, 1084) have died off, so I am looking to try and obtain some new yeast to re-introduce these back into the collection. I will also take any new strains people have come across in the last while. I will update the culture collection by this weekend when I have slanted out my remaining stock.

I may also try a new form of yeast culturing. White labs provides vials with a concentrated yeast slurry, so I am going to experiment around and see if I can grow enough yeast to provide a similar yeast slurry in our screw cap tubes. This would have several benefits over the slanting method: higher concentration of yeast cells, healthier population of cells, more viable yeast and a rough estimate of total yeast abundance (ex: each vial could contain 75-150 billion cells). However I suspect the shelf life may be less then the traditional slanting method.

[Chris Craig]

This is interesting. How labour-intensive would this be?

I think I had given Thomas 3068 for the library but I’m not 100% sure
