There are various agents which can be used for permeabilization of yeasts 
eg. toluene, ethanol, Triton x-100 and CTAB. If you need specific 
references I can pull them from my files. While working on b-gal from A. 
pullulans we compared different agents but have some references where 
people have compared them using K. fragilis
