RHODOBACTER SPHAEROIDES MUTANT STRAIN

摘要

PURPOSE: A novel Rhodobacter sphaeroides mutant strain and a medium composition containing the same are provided to remarkably promote microbe growth. CONSTITUTION: A mutant strain contains 16s rRNA having a homology of 95% or more with 16s rRNA of Rhodobacter sphaeroides(KCTC 1434) of sequence number 1. The mutant strain contains 16s rRNA of sequence numbers 2-4. A mutagen is N-methyl-N'-nitro-N-nitrosoguanidine, 4-nitroquinoline-1-oxide, or tryptopane-P-2. A medium composition for promoting growth of animal cells contains the mutant strain as an active ingredient.
