However, all Mycobacteria are quite heat sensitive. One scientific
study (Appl. Envir. Microbiol. Vol. 58: pp 1869-1873. 1992. "Heat
Susceptibility of Aquatic Mycobacteria") shows that 90% of M. marinum
are killed within 1 min at 60C. M. fortuitum, which is more heat-
resistant, takes 4 minutes at 60C.
Since Mycobacteria don't produce spores, you can easily kill them
with hot water (akin to "milk pasteurization" to kill the
Mycobacteria that cause human tuberculosis).
So I sterilize filter material with very hot water.
I would like to update my article in a month or two with more
information and scientific references. The egg sterilization thingy
needs some more investigation. :-)
