Some key secondary metabolism genes are important for driving the infection process of entomopathogenic fungi; however, their chemical substance basis has not been well investigated. Here, mixtures of polyol lipids are discovered, which are synthesized through iterative chain transfer-esterification-hydrolysis cycles catalyzed by serine hydrolase during the release of online highly reducing polyketide intermediates. Importantly, an gene knockout experiment revealed that the synthesis of polyol lipids is necessary for rodlet layer formation on the cell wall of . Our work uncovers an unexpected way for the synthesis of polyol lipids and illuminates a new perspective on their part in significant physiological processes in entomopathogenic fungi.

The advancement of bio-based materials derived from renewable resources provides a pivotal strategic approach to address the problems of environmental pollution and scarce fossil resources. In this study, a series of bio-based waterborne polyurethanes (WPUs) with enhanced UV resistance, photothermal effect and corrosion resistance were prepared by using sorbitan monooleate (SP) and castor oil (CO) as vegetable polyols together with the introduction of sodium lignosulfonate modified of diethanolamine (DML). The WPU coatings of only 100 μm thickness, exhibited UV blocking rate > 99 % between 200 and 320 nm.

This article explores the important, and yet often overlooked, solid-state structures of selected bioaromatic compounds commonly found in lignin hydrogenolysis oil, a renewable bio-oil that holds great promise to substitute fossil-based aromatic molecules in a wide range of chemical and material industrial applications. At first, single-crystal X-ray diffraction (SCXRD) was applied to the lignin model compounds, dihydroconiferyl alcohol, propyl guaiacol, and eugenol dimers, in order to elucidate the fundamental molecular interactions present in such small lignin-derived polyols. Then, considering the potential use of these lignin-derived molecules as building blocks for polymer applications, structural analysis was also performed for two chemically modified model compounds, i.
