               amounts of lysine.  In a preferred embodiment we have                  
               observed an amino acid auxotroph excreting from about                  
               3 - 10 grams/per liter L-lysine [(Spec., p. 4, lines

               invention are that it grows at a temperature of at least               
               50 C in an aqueous nutrient media that includes methanol0

               Growth requires biotin in amounts from about 20 ug 1 to. -1                 
               20 mg 1 .  When grown in minimal salts media with. -1
