摘要

棒曲霉素是由多种真菌菌株合成的有毒次级代谢产物。这种真菌毒素通常对微生物和哺乳动物有毒,因为它与重要的细胞抗氧化剂谷胱甘肽反应。在这项研究中,我们探索了能够降解棒曲霉素的微生物的存在。筛选微生物在含有棒曲霉素的培养基中生长和降低其浓度的能力。通过对510个土壤样品的筛选,分离出两株丝状真菌,其中一株Acremonium sp.TUS-MM1得到了详细的鉴定。液相色谱-质谱分析和核磁共振分析表明,TUS-MM1细胞将展青霉素降解为脱氧展青霉素酸。此外,菌株TUS-MM1的细胞外成分也表现出棒曲霉素转化活性。高效液相色谱分析显示,棒曲霉素的胞外成分产生了几种产物。使用大肠杆菌细胞进行的圆盘扩散分析显示,由细胞外成分产生的棒曲霉素转化产物比棒曲霉素毒性更小。我们还证明了细胞外成分中的一种热稳定的低分子量化合物负责棒曲霉素的转化活性。这些结果表明,菌株TUS-MM1通过分泌一种高活性化合物将棒曲霉素转化为毒性较小的分子。此外,一旦展青霉素进入细胞,菌株TUS-MM1可以将其转化为脱氧展青霉素酸,以降低其毒性。

Isolation and characterization of filamentous fungi capable of degrading the mycotoxin patulin

Patulin is a toxic secondary metabolite synthesized by various fungal strains. This mycotoxin is generally toxic to microorganisms as well as mammals due to its reactivity with the important cellular antioxidant glutathione. In this study, we explored the presence of microorganisms capable of degrading patulin. Microorganisms were screened for the ability to both grow in culture medium containing patulin and reduce its concentration. Screening of 510 soil samples resulted in the isolation of two filamentous fungal strains, one of which, Acremonium sp. TUS-MM1 was characterized in detail. Liquid chromatography-mass spectrometry and nuclear magnetic resonance analyses revealed that TUS-MM1 cells degraded patulin to desoxypatulinic acid. In addition, extracellular components of strain TUS-MM1 also exhibited patulin-transforming activity. High-performance liquid chromatography analysis revealed that the extracellular components generated several products from patulin. Disc diffusion assay using Escherichia coli cells revealed that the patulin-transformation products by the extracellular components are less toxic than patulin. We also demonstrated that a thermostable, low-molecular-weight compound within the extracellular components was responsible for the patulin-transforming activity. These results suggest that strain TUS-MM1 transforms patulin into less-toxic molecules by secreting a highly reactive compound. In addition, once patulin enters the cells, strain TUS-MM1 can transform it into desoxypatulinic acid to reduce its toxicity.

期刊介绍: MicrobiologyOpen is a peer reviewed, fully open access, broad-scope, and interdisciplinary journal delivering rapid decisions and fast publication of microbial science, a field which is undergoing a profound and exciting evolution in this post-genomic era. The journal aims to serve the research community by providing a vehicle for authors wishing to publish quality research in both fundamental and applied microbiology. Our goal is to publish articles that stimulate discussion and debate, as well as add to our knowledge base and further the understanding of microbial interactions and microbial processes. MicrobiologyOpen gives prompt and equal consideration to articles reporting theoretical, experimental, applied, and descriptive work in all aspects of bacteriology, virology, mycology and protistology, including, but not limited to: - agriculture - antimicrobial resistance - astrobiology - biochemistry - biotechnology - cell and molecular biology - clinical microbiology - computational, systems, and synthetic microbiology - environmental science - evolutionary biology, ecology, and systematics - food science and technology - genetics and genomics - geobiology and earth science - host-microbe interactions - infectious diseases - natural products discovery - pharmaceutical and medicinal chemistry - physiology - plant pathology - veterinary microbiology We will consider submissions across unicellular and cell-cluster organisms: prokaryotes (bacteria, archaea) and eukaryotes (fungi, protists, microalgae, lichens), as well as viruses and prions infecting or interacting with microorganisms, plants and animals, including genetic, biochemical, biophysical, bioinformatic and structural analyses. The journal features Original Articles (including full Research articles, Method articles, and Short Communications), Commentaries, Reviews, and Editorials. Original papers must report well-conducted research with conclusions supported by the data presented in the article. We also support confirmatory research and aim to work with authors to meet reviewer expectations. MicrobiologyOpen publishes articles submitted directly to the journal and those referred from other Wiley journals.
