I CAN NOT GIVE A SPECIFIC TEMPERATURE FOR BACILLUS LAVAE BUT AM
CURRENTLY WORKING WITH A PROBLEM WITH BACILLUS SPECIES IN FOOD
BACILLUS AS A WHOLE ARE EXTREMELY HEAT RESISTANT WITH SOME  NOT BEING
KILLED  UNTIL THE TEMPERATURE REACHES  121 DEGREES CELSIUS.
 
FOR MILK  LONG LIFE MILK IS  TREATED AT 140 DEGREES C FOR A FRACTION
OF A SECOND
 
THE BACTERIA THAT ARE OF  SIGNIFICANCE TO  FOOD SAFETY BACILLUS
CEREUS  ARE KILLED IN ACIDIC CONDITIONS  AT 80 DEGREES C. AT pH 5.0
BUT  ARE IN FACT STIMULATED  TO GERMINATE IF THE pH IS  AT APPROX. 6.5
AND ABOVE.
 
THEY ARE TOUGH LITTLE CRITTERS.
 
AS BEE KEEPERS ARE DEALING WITH WOOD  WE ARE FACED WITH THE
"PROTECTION FACTOR THAT WOOD GIVES BACTERIA AND SPORES.  SO  BOILING
THE WOOD IN AN ACIDIC SOLUTION POSSIBLY WOULD NOT KILL THE SPORES  AS
 THEY WOULD BE PROTECTED BY THE WOOD OR  THE WOOD WOULD  DISSOLVE.
 
I DON'T HAVE ANY INFORMATION ON THIS TO GIVE TRUST WORTHY  OPINION.
 
The facts are
 
Bacillus is  heat resistant  some to temperatures greater than 100
Degrees C. (212 Degrees F)
 
A combination of  acidic conditions and  heat will kill Bacillus
species
 
Wood is a protector of  bacteria as it is like a sponge when you are
the size of a bacteria
 
a reference that  could be  useful to those with access is Bergeys
Manual  of microbiology.  this is  one of the general Bibles of
microbiology
