BRYONET

In response to part of Lloyd Stark's reply:

Jane Birch at Kew Gardens put me onto a substitute for Agar in cultures.
At Kew she uses GELRITE (Sigma G-1910). There is another alternative:
GEL-GRO (ICN Biochemicals 150180).
Now, both are gellan gums. They are certainly more expensive than Agar.
But, as Jane found, the growth response on at least GELRITE is much
better for most of the species she has tried (but not all, I gather).
