我们发现，物种组合，如干酪乳杆菌亚种。rhamnosus IFO 3831和Saccharomycescerevisiae Kyokai-10在共培养中可形成混合种生物膜。此外，Kyokai-10酵母菌株可以在单培养中在来自L. casei IFO 3831.细菌CM中的活性物质对热敏感，分子量为3至5 kDa。在共培养物或CM单培养物的生物膜中，酵母细胞具有独特的形态，在细胞表面上具有许多小山状突起。
We found that species combinations such as Lactobacillus casei subsp. rhamnosus IFO3831 and Saccharomyces cerevisiae Kyokai-10 can form a mixed-species biofilm in coculture. Moreover, the Kyokai-10 yeast strain can form a biofilm in monoculture in the presence of conditioned medium (CM) from L. casei IFO3831. The active substance(s) in bacterial CM is heat sensitive and has a molecular mass of between 3 and 5 kDa. In biofilms from cocultures or CM monocultures, yeast cells had a distinct morphology, with many hill-like protrusions on the cell surface.
