[Effect of age and the amount of inoculate on the growth of Streptococcus lactis and its formation of nisin]. 1975

N S Egorov, and Iu I Kozlova, and V A Grushina

The cells of Streptococcus lactis, strain MGU, synthesize considerable amounts of nisine in the course of their growth. The rate of metabolic processes is not increased by stirring if the medium is complete and easily assimilated. Utilization of a young inoculate (1.5, 3, and 6 hours) reduces the process of nisine production by 1.5--2 times. The amount of the inoculate exceeding 1.5 volume percent has no significant effect on the biosynthesis.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D009561 Nisin A 34-amino acid polypeptide antibiotic produced by Streptococcus lactis. It has been used as a food preservative in canned fruits and vegetables, and cheese.
D003470 Culture Media Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN. Media, Culture
