许多农药产品的使用带来了它们对环境和健康的影响问题。其中，草甘膦及其助剂和副产物的影响经常被讨论。本研究的目的是通过研究农达（A（R））及其所含草甘膦对微生物模型的生长和活力的影响，揭示农达（A（R））对生物多样性和生态系统的真实的影响。Cremoris和德氏乳杆菌亚种（Lactobacillus delbrueckii subsp.）保加利亚）广泛用作传统和工业乳品技术中的发酵剂。所呈现的结果证明，Roundup（A（R））在低于农业推荐浓度的浓度下对微生物生长具有抑制作用和杀微生物剂作用。有趣的是，草甘膦在这些水平对三种研究的微生物没有显著影响。我们的工作与先前的研究一致，这些研究表明草甘膦的毒性作用通过其制剂佐剂在不同的人类细胞和其他真核细胞模型上被放大。此外，这些结果应被认为是在理解的微生物生物多样性和微生物浓度的损失观察生奶多年。
Use of many pesticide products poses the problem of their effects on environment and health. Amongst them, the effects of glyphosate with its adjuvants and its by-products are regularly discussed. The aim of the present study was to shed light on the real impact on biodiversity and ecosystems of Roundup(A (R)), a major herbicide used worldwide, and the glyphosate it contains, by the study of their effects on growth and viability of microbial models, namely, on three food microorganisms (Geotrichum candidum, Lactococcus lactis subsp. cremoris and Lactobacillus delbrueckii subsp. bulgaricus) widely used as starters in traditional and industrial dairy technologies. The presented results evidence that Roundup(A (R)) has an inhibitory effect on microbial growth and a microbicide effect at lower concentrations than those recommended in agriculture. Interestingly, glyphosate at these levels has no significant effect on the three studied microorganisms. Our work is consistent with previous studies which demonstrated that the toxic effect of glyphosate was amplified by its formulation adjuvants on different human cells and other eukaryotic models. Moreover, these results should be considered in the understanding of the loss of microbiodiversity and microbial concentration observed in raw milk for many years.
