摘要： Artificially induced mutants of the serine producing strain Corynebacterium glycinophilum ATCC 21341 which require leucine, isoleucine, methionine, tryptophan, serine, or glycine for their growth produce L-serine from glycine in higher yields than the parent strain which does not require such nutrients.

摘要： MUTANTS OF BACILLUS SUBTILIS WHICH REQUIRE ADENINE, DO NOT REQUIRE XANTHINE NOR GUANINE, AND PRODUCE INOSINE TOGETHER WITH MINOR AMOUNTS OF GUANOSINE, IF ANY, CAN BE MADE RESISTANT TO 8-AZGUANINE, AND SUCH MODIFIED MUTANTS PRODUCE USEFUL AMOUNTS OF GUANOSINE WITH ONLY MINOR AMOUNTS OF INOSINE.
