  This invention pertains to a method of counteracting a malodor in a solid or liquid, soap or detergent caused by a compound selected from the group consisting of lower carboxylic acids, thiols, thiophenols, phenols, lower amines, phosphines, arsines, lower alcohols, and lower ketones. The method comprises introducing into the solid or liquid, soap or detergent an effective malodor counteracting amount of a malodor counteracting compound selected from the group consisting of 1-cyclohexyl-ethyl-butyrate, 1-cyclohexyl-ethyl-acetate, 1-cyclohexyl-ethanol, 4-isopropyl-cyclohexyl-propionate, and phenoxyacetic acid 2-hydroxy-ethyl ester. The perceived total odor intensity in the solid or liquid, soap or detergent is reduced and the perceived malodor intensity in the solid or liquid, soap or detergent is substantially eliminated. The malodor counteractant compositions may be used in a wide variety of solid or liquid, soaps or detergents.

  本发明涉及一种抵消固体或液体、肥皂或洗涤剂中由选自低级羧酸、硫醇、噻吩酚、酚、低级胺、膦、砷化氢、低级醇和低级酮组成的组的化合物引起的恶臭的方法。该方法包括在固体或液体、肥皂或洗涤剂中引入有效量的恶臭抑制化合物，该化合物选自 1-环己基-乙基-丁酸酯、1-环己基-乙基-乙酸酯、1-环己基-乙醇、4-异丙基-环己基-丙酸酯和苯氧乙酸 2-羟基-乙酯组成的组。固体或液体、肥皂或洗涤剂中的总气味强度会降低，固体或液体、肥皂或洗涤剂中的恶臭强度也会基本消除。恶臭抑制剂组合物可用于各种固体或液体、肥皂或洗涤剂中。

  Provided is a method of preparing polylactate (PLA) or a copolymer thereof using a mutant microorganism in which a gene participating in a coenzyme A (CoA) donor- and lactate-producing pathway is genetically manipulated to increase the productivity of a CoA donor and lactate. Amounts of the CoA donor and the lactate are simultaneously increased in a microbial metabolic pathway to enable effective biosynthesis of PLA and a hydroxyalkanoate-lactate copolymer having a high content of lactate, which is industrially useful.

  本发明提供了一种利用突变微生物制备聚乳酸（PLA）或其共聚物的方法，在这种突变微生物中，参与辅酶A（CoA）供体和乳酸盐产生途径的基因受到遗传操作，以提高CoA供体和乳酸盐的产量。在微生物代谢途径中，CoA 供体和乳酸盐的数量同时增加，从而能够有效地生物合成聚乳酸和具有高乳酸盐含量的羟基烷酸-乳酸盐共聚物，这在工业上是有用的。

  Mutants of various polyhydroxyalkanoate (PHA) synthases capable of synthesizing a lactate polymer (PLA) and a lactate copolymer (PLA copolymer), and a method of preparing a lactate polymer and a lactate copolymer using the same are provided. More specifically, a mutant of polyhydroxyalkanoate synthase set forth in SEQ ID NO: 2, 4, 6, or 8, and a method of preparing lactate polymer and lactate copolymer using the mutant of synthase are provided. The polyhydroxyalkanoate synthase set forth in SEQ ID NO: 2, 4, 6, or 8 can have an activity of synthesizing a lactate polymer and a lactate copolymer by an amino acid sequence mutation affecting an activity of synthesizing a lactate polymer, and can produce a lactate polymer and a copolymer that have different features, respectively, by using the mutants of the synthase.

  Provided is a mutant of propionyl-CoA transferase from Clostridium propionicum that can convert lactate into lactyl-CoA with high efficiency in a method of preparing a polylactate (PLA) or PLA copolymer using microorganisms. Unlike conventional propionyl-CoA transferase which is weakly expressed in E.coli, when a mutant of propiony-CoA transferase from Clostridium propionicum is introduced into recombinant E.coli, lactyl-CoA can be supplied very smoothly, thereby enabling highly efficient preparation of polylactate (PLA) and PLA copolymer.
