近年来，塑料污染问题不断加重，聚氨酯作为一种常见塑料，其废弃物对环境的污染不容忽视。相对于填埋、焚烧及各种物理或化学回收手段，生物处理被认为是最环保的方法，利用微生物降解塑料也是目前的研究热点。本研究从太平洋深海沉积物中分离到一株海洋真菌沃氏霍塔霉Hortaea werneckii 13，该菌可以降解水性聚氨酯Impranil DLN。衰减全反射傅里叶变换红叶光谱(attenuated total reflectance-fourier transform infrared spectroscopy, ATR-FTIR)和气相色谱-质谱联用技术(gas chromatography-mass spectrometry, GC-MS)分析结果表明，该菌株通过断裂多元醇酯基的酯键和氨基甲酸酯基的脲键降解Impranil DLN。此外，H. werneckii 13也能够利用固态聚酯型聚氨酯作为唯一碳源生长，并使聚酯型聚氨酯薄膜发生明显失重与侵蚀。以上结果表明海洋真菌H. werneckii 13在聚氨酯废弃物生物降解及其无害化处理方面有一定的开发价值和应用潜力。"/>template{display:none;}.mag-rich-xref-fn { cursor: pointer;}//长视频$(document).ready(function(){if($("#showLongArticleVideo") && $("#showLongArticleVideo").length && $("#showLongArticleVideo").length>0){mag_ajax_update({ele_id:'showLongArticleVideo',url:mag_currentQikanUrl() + "/CN/article/showLongArticleVideo.do?id="+$("#articleId").val()});}});//可视化图谱$(document).ready(function(){if($("#showArticle_knowledgeMap") && $("#showArticle_knowledgeMap").length && $("#showArticle_knowledgeMap").length>0){jQuery.getJSON("/Jwxb/CN/lexeme/existsCnctstInArticle.do?articleID="+$("#articleId").val(), null, function(json){if(json.result){$("#showArticle_knowledgeMap").show();}});}});$(document).ready(function(){var metaDataStr = $.trim($("#article_metaJson").val());if(metaDataStr!=''){eval("window.metaData="+metaDataStr);}if(window.metaData && (!window.metaData.authorNotesCommon_cn && !window.metaData.authorNotesCorresp_cn && window.metaData.authorNotes_cn)){window.metaData.authorNotesCommon_cn = window.metaData.authorNotes_cn;}if(window.metaData && (!window.metaData.authorNotesCommon_en && !window.metaData.authorNotesCorresp_en && window.metaData.authorNotes_en)){window.metaData.authorNotesCommon_en = window.metaData.authorNotes_en;}var _nlmdtdXml = $("#article_nlmdtdXml").val();var magDir = _nlmdtdXml.replace(/\/[^\/]+$/,'');window.metaData.magDir = magDir;new mag_vue({ el: '#metaVue', //dataUrl: mag_currentQikanUrl() + '/EN/article/getRichHtmlJson.do?articleId='+$("#articleId").val(), data:window.metaData, loading:true, doTextFun:function(text){ return doDataJsonText(text);
