I have been doing some light reactivation expts on the K-12 strains. Preliminary expts indicate that W-1, Y-53, Y-10, and
680 behave like our B/r. But K-12 and 58-161 give small photoreactivation and the "q" is not constant. I'd like
to try 679 but I seem to have lost it over the summer. Apologies for any remark I may have made about other people's stocks.
May I have another 679?
Many thanks for the handy [ . . . ]. Consumer's Union describes and recommends it in its latest issue.
