2019年7月1日 · 6-Pentyl-α-pyrone (6PP) is a lactone with antibiotic and flavoring properties that is produced by Trichoderma spp. 6PP microbial production has shown low productivity and yield due to product inhibition during the growth of the producing fungus and due to the degradation of this lactone during the culture.

6-Amyl-α-pyrone, also 6-pentyl-2-pyrone or 6PP, is an unsaturated lactone molecule. It contains two double bonds in the ring and a pentyl substituent at carbon adjacent to the ring oxygen. [1] It is a colorless liquid which possesses characteristic coconut aroma, produced biologically by Trichoderma species.

作为木霉挥发性有机化合物（VOC）图谱中的主要化合物，6-戊基-2H-吡喃-2-酮（6PP）显著促进拟南芥LR的发育，早期研究证实 Thctf1 转录因子参与6PP的产生。 为了利用特定的分子调控植物RSA，作者构建了一个缺乏 IAA 和6PP生物合成的 T. guizhouense NJAU4742 ΔiaaΔctf1 五突变体。 在培养皿中，将 拟南芥Col-0 幼苗与 T. guizhouense NJAU4742和 ΔiaaΔctf1 共培养，并在与两个菌株共培养后观察到对植物根系发育的强烈刺激（图1A）。

2023年8月21日 · While ample quantitative studies have shown that 6-pentyl-2H-pyran-2-one (6PP) possesses antifungal activities against multiple plant pathogenic fungi, the regulatory mechanisms of 6PP-mediated inhibition of fungal pathogenesis and growth are still unknown.

2009年6月1日 · The system using a unique polymeric micro-material, a ballooned polyacrylonitrile microshpere (MS), was applied to the production of 6-pentyl-α-pyrone (6PP), a fungicidal secondary metabolite, with a newly isolated Trichoderma atroviride AG2755-5 and its nitrosoguanidine (NTG)-mutant. The resulted mutant AG2755-5NM398 was immobilized on the ...

1997年8月11日 · A total of 108 strains of Trichoderma sp. were compared for their ability to produce 6-pentyl-α-pyrone (6PP), a coconut-like aroma. Among them, one strain, Trichoderma viride TSP2, demonstrated a good ability to produce 6PP from several commercial vegetable oils including castor oil (C18:1, OH n-7=89.3%), hazelnut oil (C18:1=78.6%), grapeseed ...

2024年5月27日 · Among them, 6-pentyl-alpha-pyrone (6-PP), a ketone produced by Trichoderma fungi, has emerged as a focal point of interest. 6-PP has been isolated and characterized from thirteen Trichoderma species and is the main VOC produced, often accounting for >50% of the total VOCs emitted.

2019年7月1日 · 摘要 6-戊基-α-吡喃酮 (6-Pentyl-α-pyrone, 6PP) 是一种由木霉属植物产生的具有抗菌和调味特性的内酯。 由于生产真菌生长过程中的产物抑制以及培养过程中该内酯的降解，6PP 微生物生产已显示出低生产力和产量。

The final concentration of 6-pentyl-a-pyrone (6PP) produced in cultures of Trichoderma spp. is limited by the fact that inhibition of biomass growth occurs at 6PP concentrations as low as 100 mg/l. The aim of this work was to evaluate liquid-liquid extractive fermentation systems as …

2016年10月19日 · 首次探索了用于生物质衍生的6-戊基-α-小吡喃酮（6PP）增值的催化转化途径。水中6PP的开环和脱羧反应生成的非2-en-4-one化合物的转化率为95％，几乎可以...
