[Nisin biosynthesis during the joint cultivation of Streptococcus lactis strain MGU and yeasts].
In simultaneous inoculation of the medium for nisin biosynthesis with Streptococcus lactis (strain MSU) and yeasts such as Rhodotorula colostri, Zigowilliopsis californicus, Hansenuia anomala, Saccharomyces ludvigii, Kluyveromyces lactis and Endomyces magnusi the quantitative ratio of the inoculates in the mixed cultures is not in principle important for the antibiotic synthesis by the Streptococcus. When 6-, 12-, 18- and 24-hour inoculates of the yeasts were added simultaneously to 3-, 6-, 9-, 12- and 18-hour cultures of S. lactis biosynthesis of nisin was at the control level. The fractional composition of the fermentation broth of the above yeast species had no significant effect on biosynthesis of nisin.
