The biodegradation of alkylpolyglucosides (APGs) was studied under the conditions of the OECD Screening Test with activated sludge as an inoculum. An influence of alkyl and sugar chain length on the biodegradation rate and a central scission pathway of the biodegradation were investigated. The liquid chromatography-electrospray mass spectrometry technique was used for alkylpolyglucoside analysis and for identification and semiquantitative determination of metabolites. It was found that APGs with a longer alkyl chain were biodegraded faster than those with a shorter one. However, a longer sugar chain caused slower biodegradation of APGs. The central scission pathway of biodegradation was also confirmed.

液相色谱-电喷雾质谱法研究烷基多糖的生物降解。

在OECD筛选测试条件下，以活性污泥为接种物，研究了烷基多糖苷（APG）的生物降解。研究了烷基和糖链长度对生物降解速率和生物降解中心断裂路径的影响。液相色谱-电喷雾质谱技术用于烷基多糖苷的分析以及代谢物的鉴定和半定量测定。发现具有更长烷基链的APG比具有较短烷基链的APG被更快地生物降解。但是，较长的糖链导致APG的生物降解较慢。还确定了生物降解的中心分裂途径。
