“…On the other hand, the increase in the wet grain weight in the first three subcultures could also be related to kefiran production from the sugars (glucose and fructose) present in the grape juice. This hypothesis is based on the results obtained by other researchers, who observed that some microorganisms present in kefir grains, such as L. kefiranofaciens [44,45] L. lactis and L. mesenteroides [44], produced kefiran in glucose- [44] or sucrose-containing culture media [45,46].…”

“…The wet weight of the kefir grains increased significantly (p < 0.05) from 5.00 g (mass used as inoculum) up to 5.15, 5.40 and 5.40 g (after 24, 48 and 72 h of incubation, respectively), but decreased slightly (although not significantly, p > 0.05) to 5.30 g in the fourth subculture compared with the third subculture (Figure 1). The increase in the grain weight has been related to the increase in the number of cells that remain anchored to the grain during fermentation and the increase in the grain matrix weight due to kefiran production [43][44][45][46].…”

“…Учитывая возможности изотопного фракционирования -как углерода (Galimov, 1985), так и неорганических элементов, металлов (предметы компетенции металломики или элементомики (Li et al, 2008), соответственно), в ходе биогеохимической деятельности «планетарной микробиоты», можно гарантировать участие каналома и мембранома литотрофов в биологическом фракционировании изотопов в ходе формирования месторождений и выветривания (предметом мембраномики (Shimanouchi et al, 2009) для данных случаев должна являться совокупность мембран популяции, взаимодействующей посредством ионных каналов и реализующей с их помощью как фильтрующую, сорбционную и биокаталитическую функцию, так и коммуникационную / координирующую массоперенос в гомогенной по некоторому параметру среде или области среды). Нами предлагается использование для целей синхронного измерения активности каналома прокариот и результатов их биогеохимической, а также изотопно-фракционирующей деятельности техник МС-патч-клампа (Gradov, Gradova, 2015) и изотопных методов локальной фиксации потенциала (Pankratov, 2015).…”
