Appeal No. 94-3255
Application 07/673,264
(2) The specification teaches that appellants’ novel
amino acid producing auxotrophic bacterium grows at a
temperature of at least 50 C “in an aqueous nutrient media0
that includes methanol as a sole carbon and energy source with
biotin, and vitamin B " (Spec., p. 9, lines 24-26). Claim 55

appears also to be directed to amino acid producing
auxotrophic bacteria which exhibit sustained growth in a
nutrient media “comprising methanol,” i.e., in a nutrient
media that includes “carbon and energy sources for growth
other than methanol; including glucose or mannitol” (Spec., p.
10, lines 5-6).
(3) The specification appears to teach that appellants’
novel amino acid producing auxotrophic bacteria are especially
useful to produce lysine, phenylalanine, and tryptophan singly
or simultaneously in quantities from at least 5 grams 1. -1
(Spec.,
p. 14, lines 15-25) in nutrient media comprising methanol as a
sole carbon and energy source with biotin, and vitamin B .

Claim 55 appears to encompass amino acid producing auxotrophic
bacteria which produce at least about 5 g/l of lysine or any
amount of aspartic acid, phenylalanine or tryptophan, or at
