摘要:
D-ribose is produced by culturing a D-ribose-producing microorganism of the genus Bacillus, said micro-organism requiring Ltyrosine, L-tryptophan and L-phenylalanine in a proper culture medium. The accumulated D-ribose is subsequently recovered from the medium.
摘要:
Deacetylcephalosporin C is produced by cultivating a microorganism which belongs to genus Cephalosporium and is capable of producing deacetylcephalosporin C and accumulating it in the culture broth. The accumulated deacetylcephalosporin C can easily be recovered from the culture broth.
摘要:
D-ribose is produced by cultivating a strain belonging to the genus Bacillus whose transketolase activity is nil to cause said strain to elaborate and accumulate a large amount of D-ribose. The thus accumulated D-ribose can be recovered in a good yield.
摘要:
A METHOD FOR INDUCING INTERFERON FORMATION IN VIVO AND IN VITRO. TO A HOST OR A TISSUE CULTURE IS ADMINISTERED A DOUBLE-STRANDED COMPLEX OF (A) HETEROPOLYNUCLEOTIDE ESSENTIALLY CONSISTING OF INOSINIC ACID AND GUANYLIC ACID AS ITS NUCLEOTIDE UNITS AND (B) HOMOPOLYNUCLEOTIDE ESSENTIALLY CONSISTING OF CYTIDYLIC ACID AS ITS NUCLEOTIDE UNIT, THE HETEROPOLYNUCLEOTIDE (A) BEING OF A SEDIMENTATION CONSTANT FALLING WITHIN THE RANGE FROM ABOUT 2S TO ABOUT 15S IN TERMS OF SVEDBERG UNITS, AND THE RATIO OF THE AVERAGE NUMBER OF THE INOSINIC ACID UNITS THEREIN BEING FROM ABOUT 0.7 TO ABOUT 20 PER UNIT OF THE GUANYLIC ACID.
摘要:
Protease inhibitor which has strong inhibitory action against pepsin and other acid protease is produced by a microorganism of the genus Streptomyces. The protease inhibitor is recovered from the culture medium and purified and the purified protease inhibitor is used as an effective drug for the prevention and cure of hyperpepsia, hyperpepsinia and gastric and duodenal ulcers.
摘要:
5''-INOSINIC ACID AND/OR INOSINE ARE(IS) PRODUCED BY INCUBATING ADENINE-, AMINO ACID- OR/AND VITAMIN- DOUBLE OR TRIPLE REQUIRING MUTANTS DERIVED FROM Bacillus licheniformis, in a culture medium containing an adenine source and an amino acid source and/or a vitamin source.
摘要:
Method for the production of inosine which comprises inoculating an adenine and amino acid-double requiring mutant such as Bacillus pumulis Gottheil No. 3218 (ATCC No. 21005), onto a culture medium containing adenine source and amino acid source, incubating the culture medium until inosine is accumulated and recovering inosine from the culture medium.
摘要:
5''-GUANYLIC ACID, GUANOSINE OR A MIXTURE THEREOF PRODUCED BY CULTURING A MUTANT OF Bacillus pumilus Gottheil, Bacillus megaterium de Bary or Brevibacterium ammoniagenes Breed which requires both (1) adenine and (2) an amino acid and/or a watersoluble vitamin.
