An appreciable amount of C. elegans can be easily grown in liquid 
culture.  I had a lot of success growing them for bioassays.  I simply 
took about 100 mL of NG media in a 250 mL flask, inoculated with OP50, 
grew overnight and inoculated with N2 worms.  After about 5 - 7 days at 
150 rpm 24 - 28 C, I had several thousand worms/mL.  You may want to try 
this with serveral Furnbach flasks.  It may be a lot easier than dealing 
with fermenters.
Let me know if this helps.
