Pantoea(泛菌属)——肠道内善恶兼备的神秘细菌 Pantoea(泛菌属):是肠杆菌科内一个高度多样化和多变的菌属,也是肠道内神秘的“善恶兼备”的细菌。 ▸直到最近,人们对Pantoea还是一个模棱两可的认知。用研究人员的话来说: “这些物种既是植物,动物,人类的机会病原体,又能生产在除草剂,重金属螯合剂,抗生素等方面...

Pantoea ananatis is facultatively anaerobic, which like most Pantoea species are motile, produce a yellow pigment in culture, and are indole positive. The gene-encoding membrane pyrroloquinoline quinone (PQQ)-dependent glucose dehydrogenase and pqqABCDEF operon essential for PQQ biosynthesis have been id...
This is the first report of the isolation of cyclo(dehydroAla-L-Leu) from a Pantoea species. Even though tryptophol is an intermediate in the indoleacetic acid (IAA) pathway, we were unable to detect or isolate IAA. We investigated the effect of P. ananatis inoculum on the growth of ...
泛菌属基因组的测序有助于人们探索分离株在不同环境中茁壮成长的遗传因素。几种泛菌属分离株的基因组,如P. agglomerans、P. stewartii、P. vagans、P. ananatis,揭示了从 4.5 到 6.3 MB 的基因组大小和 52-55% 的 G+C 含量。 尽管迄今为止还没有对泛菌属的广泛系统比较或进化基因组分析,但在更具体的分...
Pantoea species are lysine, ODC, and arginine dihydrolase negative. They usually ferment glucose, lactose, mannitol, and sucrose, and are indole- and urease-negative. Most clinical isolates produce a yellow pigment. The genus Pantoea meaning all sorts and sources is intended to designate bacteria ...
21. SomePantoeaspecies are known to interact with plants and may confer beneficial or deleterious effects to their hosts22,23. For example,P. agglomeranswas initially identified as a cause of diseases in a wide range of hosts, such as onion, gypsophila, beet and wisteria, beach pea, cotton,...
We have previously shown that the loss of carotenoids in the plant-associated bacteria Pantoea sp.YR343 results in changes to membrane biophysical properties and leads to physiological changes, including increased sensitivity to reactive oxygen species, reduced indole-3-acetic acid secretion, reduced ...
