  • Bifunctional compounds from reaction of alkoxy hydroperoxides with metal salts
    作者:G. Cardinale、J.A.M. Laan、D. Van Der Steen、J.P. Ward

    with ferrous sulfate. C-C bond scission and radical formation was followed by dimerization of the radicals formed. Ozonides reacted similarly. Acyclic and cyclic olefins, including a cyclic enol ether, gave rise to a range of α,ω-disubstituted products in modest yields. By using ferric chloride, ω-chloro esters were obtained from the alkoxy hydroperoxides derived from olefinic esters.

  • THE FERMENTATION OF LONG-CHAIN COMPOUNDS BY TORULOPSIS MAGNOLIAE: I. STRUCTURES OF THE HYDROXY FATTY ACIDS OBTAINED BY THE FERMENTATION OF FATTY ACIDS AND HYDROCARBONS
    作者:A. P. Tulloch、J. F. T. Spencer、P. A. J. Gorin
    DOI:10.1139/v62-203
    日期:1962.7.1

    The yield of extracellular glycolipid produced by Torulopsis magnoliae is increased three-to five-fold by the addition of suitable compounds to the growing culture. The supplement, which can be a long-chain acid, ester, hydrocarbon, or glyceride, is hydroxylated and converted to hydroxy fatty acid sophorosides. Fatty esters of all chain lengths from C16to C22, including several unsaturated esters, and even-numbered hydrocarbons from C16to C24are readily fermented. Shorter-chain compounds are used poorly or not at all. With compounds of 16 to 18 carbon atoms, hydroxylation occurs at the terminal or penultimate carbon atom, depending on degree of unsaturation and chain length. Substrates of more than 18 carbon atoms are mainly reduced in chain length by one or more two-carbon units and hydroxylated, giving C17or C18acids with the hydroxyl group on the penultimate carbon atom. The various enzymic reactions which occur during the fermentation are discussed.

    扩大培养基中添加适当化合物可将Magnoliae酵母产生的细胞外糖脂产量提高三到五倍。这种添加剂可以是长链酸、酯、碳氢化合物或甘油酯,经过羟基化后转化为羟基脂肪酸索非酮苷。从C16到C22的所有链长的脂肪酯,包括几种不饱和酯,以及从C16到C24的偶数碳氢化合物都容易发酵。较短链的化合物使用效果不佳或根本不使用。对于含有16到18个碳原子的化合物,羟基化发生在末端或次末端碳原子上,取决于不饱和度和链长。含有超过18个碳原子的底物主要通过一个或多个二碳单位减少链长并进行羟基化,从而在次末端碳原子上带有羟基的C17或C18酸。讨论了发酵过程中发生的各种酶反应。

    Described herein are formulations and methods of reducing spoilage in harvested produce by reducing the rate of water or mass loss, thereby resulting in high quality produce with lower rates of spoilage. The present disclosure provides coatings and methods of coating produce to prevent moisture loss from produce during storage and shipment of the produce. This in turn allows the produce to be shipped and stored at lower relative humidity (e.g., lower than industry standards for shipment and storage, or lower than about 90% relative humidity), which can help delay the growth of biotic stressors such as fungi, bacteria, viruses, and/or pests.
    本文描述了一种减少收获农产品变质的配方和方法,通过减少水分或质量的流失速率,从而获得质量高、变质率低的农产品。本文提供了覆盖物和覆盖农产品的方法,以防止农产品在储存和运输过程中失去水分。这反过来允许农产品在较低的相对湿度下运输和储存(例如低于行业运输和储存标准或低于约90%的相对湿度),这可以延迟生物胁迫因素(如真菌、细菌、病毒和/或害虫)的生长。
